Midi Light Show using Arduino

For a class, my teammate and I decided to develop a MIDI based system that has a responsive light for each note played.  For example, if you plug our little setup to a keyboard, pending on which note you press, you'll get a specific color.  You'll need a list of several items, but the reward is quite nice!  Plus, there are a lot of possible improvements and developments from the original idea ...

Arduino-compatible board for the OLPC XO laptop

Dr. Scott Ananian, from the One Laptop Per Child (OLPC) project, conceived an Arduino Leonardo-compatible board especially designed for the OLPC XO laptop, with the goal to cut down its price as much as possible, to foster its adoption even in developing countries. From Scott’s blog: The board, named XOrduino, is open hardware (schematics and pcb files can be found on github), and can be directly plugged in ...

Arduino Thermostat (Mechanical)

I am currently living in a college dorm. Like most dorms it's about the size of a tissue box but less comforting. Fortunately, my room has a heater/AC with four positions: low, medium, high, and off. Unfortunately in winter an hour on the low setting makes the room a stifling 80 degrees and when turned off it drops quickly to 60 degrees. My solution uses an arduino, temperature sensor, and motor to automati ...

Simplified Electric Imp to Arduino Due Tutorial

Introduction: This is a basic tutorial to send information from the Electric Imp to the Arduino Due through UART (RX, TX) I am pretty new to both so some things I write may be incorrect. Most of the information I got from https://www.sparkfun.com/tutorials/397 If you know how to program well that tutorial may be way better then this one, but I thought this would be a more basic and easier tutorial for peopl ...

How many robots?

How many robots run on Arduino? I really don’t know. The guys from Complubot keep on sending pictures from the robots they are finding at the Robo Cup in Mexico DF. Want to see some pictures? Look at the following: The Japanese Team on Soccer B have been working with Arduino for 3 years now. The robots on the picture are only using our IDE, as they made their own PCBs to host 8 InfraRed sensors, a compass, ...

Digital multimeter shield for Arduino

This instructable describes a shield, which converts "Arduino" board in a digital multimeter (DMM). The shield can be inserted on "Arduino" UNO und Duemilanove boards. It can work in three modes: standalone - the measurement data can be seen at the character or graphical LCM connected - the measurement data can be read on the PC screen using the "Arduino" IDE "Serial monitor" combined - the data can be obse ...

Arduino Basics: Working One LED

I've been encountering lots or Arduino projects but generally most are on intermediate and advanced level and only a few basic instructions on how to start with Arduino. This project I made were actually inspired by this example on the Arduino page, but a much in depth step by step instructions. Assuming that you already have the basic idea on the parts and pin assignments of Arduino, you can now skip readi ...

LM3916 LED bargraph/ VU meter

Brief description: This kit builds on a famous LM3916 VU bargraph driver chip from TI/National semiconductor. The chip is essentially a constant current 10 segment driver fed by an array of comparators. It also provides internal reference voltage to set the rail of the precision resistor network feeding the comparator reference inputs. A signal coming in then determines how many signals are lit. Depending o ...

3D Printed Digital Camera

This is a 3D printed digital camera that you can build yourself. By making your own digital camera, it takes away some of the mystery around how such devices work, and are fabricated. Also, it allows you to fully customize the camera to your liking. You can expand the circuit to have new functionality, or design your own custom case by modifying the 123D Design build files. While this may not be a high-reso ...

Acrylic Arduino Prototyping Stand

I do a lot of projects with Arduino's and breadboards.  Often as I work on a messy workbench, the Arduino or breadboard get jostled and the wires pop out of the headers or the breadboard. To solve this problem, I decided to make a simple acrylic stand for mounting an Arduino and a breadboard that would prevent them from moving around. I used a laser cutter to cut the acrylic to size, to cut the holes f ...
