I recently dug up my old RC transmitter and receiver and thought “How can i control my arduino with this?” so i powered on my scope to see what was going on at the receiver. Sure enough, it was sending out the standard PWM signal that servos use. Now I just needed something to control. What’s easy

This example shows how to use the tone() command to generate different pitches depending on which sensor is pressed. Circuit Connect one terminal of your speaker to digital pin 8 through a 100 ohm resistor, and its other terminal to ground. Power your three FSRs (or any other analog sensor) with 5V in parallel. Connect each

I made the original Instructible that this is based on over a year ago (You can see it here to see some of the theory around how this works:http://www.instructables.com/id/How-to-access-5-buttons-through-1-Arduino-input ). To make a long story short, I moved to a different country a few weeks after that and have not played with any electronics since.

This instructable shows you how to build a Web-enabled tri-color LED based on an Arduino and the WIZnet Ethernet shield, controllable from any Web browser . Check the live demo at http://try.yaler.net/~arduino/led Because the LED is exposed through a simple RESTful web service running on the Arduino color changes can also be triggered by Pachube

First of all, I’m from Switzerland so please excuse my english mistakes. Here is one of my first little project I did with my Arduino Uno. It’s is just a little light seeker. The servo turns towards the light. Step 1: The wiring Here is the exact wiring I used. The only difference is that

This project emulates a trumpet by playing notes using the three buttons (valves). This is easy to make and fun to play with, though it can only play one octave and no sharps/flats. Step 1: Code Load this into your Arduino: int speaker = 9; // Hook up speaker to digital pin 9 int sw1

My First ever Robot. It tracks objects using Infra-red sensors, and has basic AI that follows and avoid objects. I will describe the how I made this robot, and upload some videos. Version 1 (16 Dec 2011): —————–The components used ———————- I actually planned this robot before making it. I didn’t use all the parts

Breadboards are very handy, but sometimes I just want to connect one IC or some LEDs and resistors to the controller. My simple solution was to canibalize a cheap Breadboard to get two expandable PrototypingShields with some additional features. What I used: Breadboard (~3$) 2 Pieces of Veroboard (<1$) 28 PinHeader (<1$) 28 femaleConnectors (<1$)

The goal of this instructable is to make a no solder arduino breadboard shield like this one: Step 1: You will need Parts list: Super glue*Mini breadboard size 4.5×3.5 cmArduino pin headers** * Hot glue wont cut it** Normal female pin headers can also work Optional, but recommended: ArduinoSmall clampsSand paper Step 2: Sanding

Welcome to my first Instructable! This is for something I’ve coined the “Tweety” or, Tweety-Button. The concept is simple, you’re on your computer and the inspiration to Tweet is welling up inside. Chrome is being slow today, and you want to get those 140 characters out, fast! No fear, just click on the Tweety button
