I knew there were devices that could trigger a camera to fire during a lightning strike, but their circuits were more complicated than I wanted to make. I’m a software guy not a hardware guy so I decided to use an Arduino and that allowed me to write a little code that made the circuit much simpler. Before I

This instructable assumes very little with respect to prior knowledge. If there are any areas you feel could be improved or clarified, please feel free to message or comment and I will update. Here are all the details you need to produce a simple wall avoiding robot. Along the way you will have the chance

Hey! Some time ago while going through the pages here in Instructables, something catch my attention, a printer made of a CD reader, and i was amazed. I thought: “This is incredible, I have to make one!” I know that these kind of projects don’t always receive a “I made it”, because of its degree

BMO from Comedy Central’s Adventure Time is adorable, if only someone would make one that can walk! Atleast we can make one with a personality. Here is a build using easy to get parts including Arduino Pro Mini, Nokia 3310 LCD screen, audio playback, accelerometers, and distance sensors. The parts added up to around $70.00

This Instructable will show you how to make a Portable Digital Optical Tachometer using an Arduino Uno. This project is inspired from This instructable and is an enhanced version of it with an LCD display and a modified code. Instead of a slotted sensor , it has a reflection based sensor. So : 1. You

RC cars can be WiFi Cars…? RC cars are cool, but cheap RC cars have limited range and can only be controlled with the particular controller that was included with the car. I purchased a RC jeep, complete with 4 wheel drive, flexible suspension, and off-road tires for about 30 bucks. Not long after playing

This instructable shows how to modify an inexpensive RC car so it can be controlled by an on-board microcontroller. You can program the controller to make the car do any number of driving patterns and stunts. Once you have the car being controlled from the on-board controller, you can add sensors for light and sound

This will explain how we re-purposed a hand drill to re-spool solder using a roboduino (arduino compatible), two servos, and a DIY encoder. While one could use TRIACs to play with the AC power going into the drill, just using a servo to control the throttle is simple and avoids the pesky high voltage. Hand drills

When I first got into the Arduino I went looking for audio projects. One of the first things I built was TobaTobias’ Auduino granular synth. I was so impressed I built a permanent unit in a heavy duty enclosure and incorporated it into my occasional sets and demos.. This simple project makes really impressive sounds-
