If you have ever wanted to control high voltages/currents with an Arduino, setup up a complicated light timer, or even have Siri turn on a Lamp. Then this is an instructable for you! In this instructable in a few simple steps we will build a self-powered smart relay (Arduino style) power box. This box will allow […]

Introduction Disclaimer: I am not an expert in any of this. There is lots of information online regarding such designs. Although this setup worked for me, do not trust any of my calculations. Please work all this out for yourself and consult many other sources, or it may spontaneously burst into flames. The contraption is

Building upon our last tutorial, which taught you how to build a muscle sensor, we’ve decided to give you a project that really showcases the power of our muscle (EMG) sensors. Advancer Technologies’ “USB Biofeedback Game Controller” harnesses the power of electromyography to allow players to directly control video games with their muscles. At the core

To connect up a CT sensor to an Arduino, the output signal from the CT sensor needs to be conditioned so that it meets the input requirements of the Arduino analog inputs: a positive voltage between 0V and the ADC reference voltage. Note: This page give the example of an Arduino board working at 5 V and

A desktop motorized musical disco ball. Great for holiday parties, impromptu dance-offs, and Tuesday afternoons. Bling, Music, Arduino, and glitter covered styrofoam; this Instructable has got what you need to get your boogie on. Fires need help go get going, so do parties. I recently moved from Hartford where my boys @HPSU(http://hartfordpartystarters.org/) would get it started

John has been working to recover components from old power supplies and available trash electronics, in order to build controllers to power stepper motors and other mechanisms for the FabLab. Intro The Arduino microcontroller board is able to supply a current of 40mA from its output connections. These digital outputs are fixed at 5V “ON”

Overview In the first serial lab, you sent data from one sensor to a personal computer. In this lab, you’ll send data from multiple sensors to a program on a personal computer. You’ll use the data from the sensors to create a pointing-and-selecting device (i.e. a mouse). (:toc Table of Contents:) Connect the sensors Connect

About 2 years ago I picked up a ADJD-S371 color sensor from Sparkfun to work with my arduino. I spent a few days getting it to work, but finally got it going pretty well. I still get a few emails here and there asking for help with it. So I figured I would start bildr’s

It’s a telepresence robot I built for our office, consisting of an iPad mounted on a lightweight chassis powered by an RC car. To operate it, you open up a video chat session with the iPad, then control the robot from your browser using the web interface. PETBOT can see, move, talk, and, like any
