<\/a><\/p>\nThe Raspberry Pi and similar devices are different. They are called single-board computers. They are literally $35-50 computers, smaller than a deck of cards. They can also be used by hobbyists to build things. While there is some overlap, they usually are appropriate for different applications. That\u2019s all I am going to explain.<\/p>\n
One thing these devices have in common is that they work with computer programs, and I have always been interested in computer programming. I have done a little of it over the years, having written a program to calculate child support, created pretty complex macros for Excel spreadsheets and other kinds of fairly simple programs. I will never make it as a Programmer, but programming for me is like crossword puzzles for a lot of people.<\/p>\n The new \u201ctoy\u201d I got was an Arduino Starter Kit. It comes with the microcontroller on a circuit board and all sorts of parts to do things like measuring temperature and light, light blinking, making sounds, and a bunch of other things. The kit came with a book of instructions for designing the circuits and writing the programs that control them. Unfortunately, I will have to learn a new programming language in order work this stuff, but that\u2019s part of the point of the kit. While I am spending more time at home helping Janie out, she is indulging yet another geeky whim of mine by encouraging me to get the kit.<\/p>\n I heard a guy on a podcast say recently that it is better to learn this stuff with a project in mind or a problem to solve. In general, I would agree, but I\u2019m still at the stage where I don\u2019t know what I don\u2019t know. So, going through the exercises in this kit will give me an idea about what projects I might want to do. After I get deeper into the Arduino, I\u2019ll move on to the Raspberry Pi, and see what it can do. (When I told Leslie that I was interested in the Raspberry Pi, she asked in all seriousness \u201cYou\u2019re going to make a raspberry pie?\u201d Sorry, Leslie, that will come later.) My interest in these devices was rekindled after getting involved in ham radio, because I learned that there were several applications that could be used in that hobby. As I learn about their capabilities, I can decide what problems I want to solve it radio or one of my other hobbies.<\/p>\n Having explained this to a couple of people recently, I realized that what is very familiar to me may be totally foreign to some of my circle. So, if you\u2019ve never heard of them, I will describe what an Arduino … Continue reading <\/a><\/p>\n+1<\/span><\/a><\/div>0<\/span><\/a><\/div> <\/div>
