Engineering ToolBox. 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. One kind of switch you use every day is a light switch. A light switch is a simple device with two positions, on and off. When on, two wires are connected inside, which allows current to flow. When off, the two wires are disconnected. 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. Find 5 things around the house that have switches. Switch capability Fig 5.2 Valid inputs. ENGINEERING.com | The Engineer's Ultimate Resource Tool. BeagleBoard.org - default.

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? The Relay Bread Board and building a LED Flasher Building the LED Flasher Astable Multivibrator using two transistors.

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. This book is not new – the truth is that it has changed little since it’s first release in 1983. Despite this, twenty-five years later, there is really nothing else like it. This book is suitable for beginners of any age yet it comprehensively describes the technical theory and practical use of electronic devices like resistors, capacitors, inductors, diodes, transistors, FETs (including the now-rare JFET), and LEDs, as well as circuits like amplifiers, oscillators, and logic gates.

There is even a graphical introduction to device physics (semiconductor materials, doping, electrons and holes) and semiconductor fabrication! This is kind of stuff they teach third-year students in university ECE classes, written in a way that is understandable to a child in third grade! The entire book is formatted like an engineering notebook with handwritten notes on every page. . The Hobby Electronics from Japan - Menu. Online Circuit Simulator with SPICE.
