This is an audio spectrum VU meter using the LoL Shield for Arduino . The LoL Shield is a 14 x 9 LED matrix which fits onto the Arduino as a shield and is controlled through an efficient method known as Charlieplexing . It was designed by Jimmie P. Rodgers . This project uses a […]

I am a Physicist and the nicest part of working in this field is that I get to build my own instruments. With this way of thinking, I decided to build a homebrew Arduino Oscilloscope. This instructable was written with the purpose of teaching a bit about microcontrollers and data acquisition. This is an extreme

This is a relatively inexpensive and easy to build project that will help you test out all of your Arduino projects and prototypes. Since it has a plug-in power source, it eliminates frequent battery use and leaves the breadboard free of voltage regulators and capacitors providing more room for projects. However, if you need battery

Hey guys, I’m back with another instructable. This is about RC speed controllers. What this will do is allow you to test out your speed controller in the Arduino world using Serial, then you write the values down and can use them for your projects. Submitted by Newton Labs for the Instructables Sponsorship Program Step
Controlling speed controllers with Arduino Continue Reading
Thanks to Will Greiman’s Fat16 library for the Arduino, I finally got a useful version of this datalogger working! Here’s the schematic: And here’s the code. The code is highly configurable: it can save raw A/D values or converted values, it allows software-defined gain, it can collect for a set time or until user input,
