Arduino Tutorial Lesson 4. Ah, Arduino, I remember when you were just crawling around and blinking LEDs. Now youre ready to learn how to speak In this lesson well learn how to use the Serial Library to communicate from the Arduino board back to the computer over the USB port. Then well learn how to manipulate numbers and data. For this lesson we wont be using the shield, so simply remove it keeping the mood light LEDs on it youd like. Adaptations of works which have achieved classic status. SerialtoEthernet Device Servers 3 www.

Casey Noland, a high school kid with no direction in life, decides to pursue the serial killing profession. Only problem. he cant bring himself to kill anybody. Download the latest drivers for your Gadget Serial v2. Computer uptodate. The shield doesnt contain any programs or data, it is just our way of connecing up the LEDs and resistors. Well use the shield again but for now, we can examine the RX and TX LEDs on the main Arduino board which will help you with debugging Libraries are great places, and not yet illegal in the United States If you ever need to learn how to do something, like say fix a motorcycle, you can go to your local library and take out a book. Sure you could buy the book but the library is nice because as a resource you can get the book whenever you need it, keeping your house uncluttered. Software Libraries are very similar. We already studied what a procedure is, in lesson 3 a procedure is a list of things to do. A library is a big collection of procedures, where all the procedures are relatedIf you, say, want to control a motor, you may want to find a Motor Control Library a collection of procedures that have already been written for you that you can use without having to do the dirty work of learning the nuances of motors.

The library we will be using is the Serial Library, which allows the Arduino to send data back to the computer Serial may sound like a tasty breakfast food, but its actually quite different. The word serial means one after the other. For example, a serial killer doesnt stop with one murder, but stabs many people one after the other. Serial data transfer is when we transfer data one bit at a time, one right after the other. Secrets Of The Master Prospectors Pdf: Software Free Download. Information is passed back forth between the computer and Arduino by, essentially, setting a pin high or low. Just like we used that technique to turn an LED on and off, we can also send data. Lookbook No. 4 features patterns and projects, too knitting, quilting, embroidery, and even a recipe for homemade cookies give readers a chance to explore their own. Thanks for the history lesson. I thought I read somewhere that an Iver Johnson was used to shoot a president. I have NO idea if the revolver. Serial key for Daemon Tools Lite 4. We have the largest serial numbers data base. Serial 4' title='Serial 4' />One side sets the pin and the other reads it. Its a little like Morse code, where you can use dits and dahs to send messages by telegram. In this case, instead of a long cable, its only a few feet. This is as good as Microsoft Visio can do, yayNow, people who are all geeked out will probably get angry at this point because Im simplifying things. Well guess what, its an Arduino tutorial, not a OSI Physical Network Architecture tutorial. The world isnt run by weapons anymore, or energy, or money. Its run by little ones and zeroes, little bits of data. Its all just electrons. Sneakers Now is a good time to review how data is measured. For example, we measure weight with ounces and pounds or grams and kilograms and distances with inches, feet, and miles or centimeters, meters and kilometers. Information has its own system of measurements A single bit is either a zero or a one. You can group bits together into 8 bits which is 1 byte. Kilobyte sometimes written KB. KB 1. 04. 85. 76 bytes is one Megabyte MB1. MB is 1 Gigabyte GBAn interesting thing to note is while 1. That is, a 1. 0 Kilobyte file on your computer is 1. If your hard disk is 2. Gigabytes, how many bytes is that Use a calculator with lots of digits Highlight the text below for the answer. GB 1. 02. 4 2. MB2. MB 1. KB2. 09. 71. KB 1. Hard drive makers are quite sneaky, youll notice that they define GB as being 1. MB, and 1 MB 1. KB, etc. Given this fact, how many bytes can you really store in your 2.

KBHow much less storage do you get thanks to the marketing guy who came up with this trickHighlight the text below for the answer. About 4. 6 less than youd expect Weve actually used the Serial communications capability already quite a bit. Arduino When you CompileVerify what youre really doing is turning the sketch into binary data ones and zeros. When you Upload it to the Arduino, the bits are shoved out one at a time through the USB cable to the Arduino where they are stored in the main chip. Next time you upload a sketch, look carefully at the two LEDs near the USB connector, theyll blink when data is being transmitted. One blinks when the Arduino is receiving data RX and one blinks when the Arduino is transmitting data TX Enough chatting amongst ourselves, its time to get the Arduino talking. Our first sketch is going to be the hello world When it starts up, it will say hello worldCreate a New Sketch. Hello. World. Into the new sketch, copy and paste the following source code, then save it voidsetup. Serial. begin9. 60. Serial. printlnHello world. OK first thing to notice is that theres nothing in the loop procedureWeve gutted it. Even if we have nothing in the setup or loop procedures, the Arduino requires them to be there. That way it knows you really mean to do nothing, as opposed to forgetting to include them The first line of code in the setup procedure is this one We definately see that there is a Serial thing going on, and it looks like there is a procedure call as well. This is a library procedure call. The library is called Serial and inside the library is a procedure called begin. Serial. begin9. 60. If theres no library name, it means that the procedure is in the default collection of procedures we use. For example, delay is so common, the designers of the Arduino software didnt bother putting it into a library. So theres some mystery procedure thats called begin, well its not too tough to figure out what it might do. Its the procedure that gets the Serial stuff ready. But whats the 9. The comment says 9. If you have broadband connection, you may remember reading somewhere that it has, say 3. This is how fast the connection can read and write bits on the wire. Needless to say, your broadband connection can transfer data a lot faster than an ArduinoOK so Serial. Arduino with the transfer rate we want, in this case 9. Lets move on to the next line. Serial. printlnHello world This line also uses the Serial library, this time its calling a procedure called println which is just a shorthand for print line. Note that the 6th letter in println is the letter L not the number 1. This time the input is a quotation, the line of text we would like it to print. We use two s double quotes to indicate the beginning and end of a line of text. If the Arduino transfers data at 9. Highlight the text below for the answer. If we can transfer 9. If the Arduino transfers data at 1. Highlight the text below for the answer. This is twice as fast as before, so it will take half the time, about 12. Good, now compile the sketch and upload it to your Arduino. It looks like not much is going on here. Somewhat disappointing since we had so much fun with blinking colored lights before. The trick here is that while you can see blinking lights quite easily, seeing serial data requires a monitor, which like your display monitor will show us what data is being transfered. Lucky for us, theres a serial monitor built into the Arduino software Im not quite sure what the icon means, but regardless if you click that button you will replace the black Program Notification area with a Serial Monitor. So. click it What happens next is, sadly, quite dependent on which kind of Arduino you have Windows. Serial killer Wikipedia. A serial killer is typically a person who murders three or more people,1 usually in service of abnormal psychological gratification, with the murders taking place over more than a month and including a significant break a cooling off period between them. Different authorities apply different criteria when designating serial killers 3 while most set a threshold of three murders,1 others extend it to four or lessen it to two. The Federal Bureau of Investigation FBI, for example, defines serial killing as a series of two or more murders, committed as separate events, usually, but not always, by one offender acting alone. Although psychological gratification is the usual motive for serial killing, and most serial killings involve sexual contact with the victim, the FBI states that the motives of serial killers can include anger, thrill seeking, financial gain, and attention seeking. The murders may be attempted or completed in a similar fashion, and the victims may have something in common age group, appearance, gender, or race, for example. Serial killing is not the same as mass murdering killing numerous people in a given incident nor is it spree killing in which murders are committed in two or more locations, in a short time. However, cases of extended bouts of sequential killings over periods of weeks or months with no apparent cooling off period or return to normalcy have caused some experts to suggest a hybrid category of spree serial killer. CharacteristicseditGeneraleditSome commonly found characteristics of serial killers include the following They may exhibit varying degrees of mental illness or psychopathy, which may contribute to their homicidal behavior. For example, someone who is mentally ill may have psychotic breaks that cause them to believe they are another person or are compelled to murder by other entities. Psychopathic behavior that is consistent with traits common to some serial killers include sensation seeking, a lack of remorse or guilt, impulsivity, the need for control, and predatory behavior. Unlike people with major mental disorders such as schizophrenia, psychopaths can seem normal and often quite charming, a state of adaptation that psychiatrist. Hervey Cleckley called the mask of sanity. They were often abusedemotionally, physically or sexuallyby a family member. Serial killers may be more likely to engage in fetishism, partialism or necrophilia, which are paraphilias that involve a strong tendency to experience the object of erotic interest almost as if it were a physical representation of the symbolized body. Individuals engage in paraphilias which are organized along a continuum participating in varying levels of fantasy perhaps by focusing on body parts partialism, symbolic objects which serve as physical extensions of the body fetishism, or the anatomical physicality of the human body specifically regarding its inner parts and sexual organs one example being necrophilia. A disproportionate number exhibit one, two, or all three of the Macdonald triad of predictors of future violent behavior. They were frequently bullied or socially isolated as children or adolescents. For example, Henry Lee Lucas was ridiculed as a child and later cited the mass rejection by his peers as a cause for his hatred of everyone. Kenneth Bianchi was teased as a child because he urinated in his pants, suffered twitching, and as a teenager was ignored by his peers. Some were involved in petty crimes, such as fraud, theft, vandalism, or similar offenses. Often, they have trouble staying employed and tend to work in menial jobs. The FBI, however, states, Serial murderers often seem normal have families andor a steady job. Other sources state they often come from unstable families. Studies have suggested that serial killers generally have an average or low average IQ, although they are often described, and perceived, as possessing IQs in the above average range. A sample of 2. 02 IQs of serial killers had a median IQ of 8. There are exceptions to these criteria, however. For example, Harold Shipman was a successful professional a General Practitioner working for the NHS. He was considered a pillar of the local community he even won a professional award for a childrens asthma clinic and was interviewed by Granada Televisions World in Action. Dennis Nilsen was an ex soldier turned civil servant and trade unionist who had no previous criminal record when arrested. Neither was known to have exhibited many of the tell tale signs. Vlado Taneski, a crime reporter, was a career journalist who was caught after a series of articles he wrote gave clues that he had murdered people. Russell Williams was a successful and respected career Royal Canadian Air Force Colonel who was convicted of murdering two women, along with fetish burglaries and rapes. DevelopmenteditMany serial killers have faced similar problems in their childhood development. Hickeys Trauma Control Model explains how early childhood trauma can set the child up for deviant behavior in adulthood the childs environment either their parents or society is the dominant factor determining whether or not the childs behavior escalates into homicidal activity. Family, or lack thereof, is the most prominent part of a childs development because it is what the child can identify with on a regular basis. The serial killer is no different from any other individual who is instigated to seek approval from parents, sexual partners, or others. This need for approval is what influences children to attempt to develop social relationships with their family and peers, but if they are rejected or neglected, they are unable to do so. This results in the lowering of their self esteem and helps develop their fantasy world, in which they are in control. According to the Hickeys Trauma Control Model the development of a serial killer is based on an early trauma followed by facilitators e. Family interaction also plays an important role in a childs growth and development. The quality of their attachments to parents and other members of the family is critical to how these children relate to and value other members of society. Wilson and Seaman 1. Almost all of the serial killers in the study had experienced some sort of environmental problems during their childhood, such as a broken home caused by divorce, or a lack of discipline in the home. It was common for the serial killers to come from a family that had experienced divorce, separation, or the lack of a parent. Furthermore, nearly half of the serial killers had experienced some type of physical or sexual abuse, and even more had experienced emotional neglect. When a parent has a drug or alcohol problem, the attention in the household is on the parents rather than the child. This neglect of the child leads to the lowering of their self esteem and helps develop a fantasy world in which they are in control. Hickeys Trauma Control Model supports how the neglect from parents can facilitate deviant behavior, especially if the child sees substance abuse in action. This then leads to disposition the inability to attach, which can further lead to homicidal behavior, unless the child finds a way to develop substantial relationships and fight the label they receive.
