Beginners Guide Beginners Guide to Electronics by Martin T. Pickering Last updated on November 23, 2008 This book gives simplified explanations of how some electronic components work in a circuit. I first became interested in electronics when I was age 10 (as long ago as 1961). ©2008 Martin T. What's the Difference between A.C. and D.C.? How does a Resistor Work? All the colours for 5% tolerance resistors: How do Diodes Work? How do Transistors Work? Abbreviations Although we use the Greek symbol Omega W to represent “Ohms” it is frequently written as “R”. How does a Capacitor Work? What does a capacitor look like? How do Inductors Work?

Maker Education Initiative | Every Child a Maker Engineering ToolBox Bubble Machine These are the tools and materials that I used for my bubble machine. Yours will differ greatly depending on what you have available. This is a great project to do with scraps, and odds and ends all hacked together. To make it easier for others to reproduce this, I've done away with my normal format of exactly what to use and instead broken it down into the five main components the machine's made from. Trough: To hold the bubble solution. Bubble Ring: A ring of holes that will spin slowly through the trough picking up the bubble solution. Motion: A slowly moving motor to spin the bubble ring. Blower: Something with a bit of puff. Power: A power source or two for the blower and spinner. You'll also need nuts, bolts, hot glue or superglue to hold everything together. The files I used for laser cutting are included in this step.
Arduino Tutorial - Lesson 5 We've done a lot so far, blinking lights, printing messages...all of that stuff is output: signals coming from the Arduino. The next step is to start playing with input, with the Arduino responding to outside events. In this lesson we will begin with the most basic kind of input, a push-button switch! You're probably familiar with switches, there's tons of them in your house. On the left, the switch is open and no current flows. (thanks wikipedia!) In this photo, you can see the internals of a light switch. Light switches are great but we need something smaller. These little switches are a 1/4" on each side, cost about 25 cents, and can plug directly into a breadboard. Normally, the two wires are disconnected (normally open) but when you press the little button on top, they are mechanically connected. To get the buttons to sit better in the protoshield, you may want to straighten out the legs (just squish them with a pair of pliers) so that they look like the button on the left. Fig 5.2
BeagleBoard.org - default Hobby Engineering Home Page Blog Archive » The greatest electronics book ever written? Getting Started in Electronics , by Forrest M. Mims, III. is a spectacular introduction to the world of electronics. The entire book is formatted like an engineering notebook with handwritten notes on every page. My father gave me this book when I was six or seven years old along with a 25 watt soldering iron from Radio Shack. Forrest Mims himself is an interesting individual and has led a prolific career as a writer and amateur scientist. The book even includes a handy guide to help you learn How to Solder! Thankfully, it turns out that this fantastic book is still in print . In my opinion, this is probably the greatest introductory book about electronics ever written. Happy 25th, Getting Started in Electronics! Like this: Like Loading... Tags: books, Books and Resources, Electronics, Forrest Mims, Radio Shack
