Once you’re getting some values from sensors, for example using Arduino, (see my previous instructable), sometimes it’s nice to see the sensor data in a graph. Here’s how in only a few steps! I made this particular Instructables using a sonar sensor (XL Max Sonar EZ/AE) but you can do it with any data values […]

Make a game pad with an accelerometer inside! This project tutorial will show you how you can convert a console game pad into a USB keyboard mouse for playing games on your PC. The USB game pad can be used with nearly any software, such as a MAME emulator, game, simulation software, or for custom

In an earlier post I described an Arduino-controlled fan cart. The driver I used was an L293D quad half-H chip, because I had one handy and was out of simpler parts at the time. It’s always bugged me that I was just controlling speed on that cart, since it’s possible to control direction with an
This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Making a plant sing has been a trick since the Theremin was invented. Here I am going to teach you how to do this with and arduino board, a gameduino shield and a the touch shield

This is the second part of our BaW-Bot (Bells-and-Whistles Bot) build – 5 separate instructables that look into different Arduino-related technologies, combining to create a Bot with all the bells-and-whistles. Part 1: Build an Arduino on a Board Part 2: Build the motor-controller & body Part 3: Adding Sight and Touch Part 4: Blinging up

One of my colleagues, Dr. Shane Mayor, has built a very nice LIDAR system for atmospheric research. It’s located at a remote site, at the end of a dirt road, and everything about the system can be controlled remotely except the main pump laser power supply. That supply has a key-switch, which has to be
To connect a 12V relay to the Arduino you need the following things: – 1 Arduino – 1 diode for example 1N4007 – 1 NPN transistor for example 2N2222 (in the US) or BC548 (in Europe) – 1 relay for example one with coil voltage 12V and switching voltage 125VAC/10 A – 1 multimeter Step
Being a broke amateur photographer isn’t easy. Film, chemicals and paper aren’t cheap and a budget for some studio lights is non existant. So, I decided to, with the help of my trusty arduino, create my own sync controller to use with disposable camera flash circuits. By using a photoresistor the arduino can sense when the flash from your
I’m currently helping a couple of engineering students finish a senior project that didn’t get finished last year. Long story… Anyway, it’s a bicycle brake tester being built for Paul Components. The mechanical design is great, but they had trouble with the electronics. Part of those electronics involved writing numbers to a pair of Sparkfun
Driving multiple Sparkfun 7-segment displays with an Arduino Continue Reading
After a bad water damage (our cellar basically filled up whilst we were away for several days), I decided to monitor our water usage for anomalies. Enters Arduino… The idea of this project is to use an arduino to count every drop of water that goes through the water company meter. Said arduino needs to
