Major corrections and additions made 9/9/2014 For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There’s a couple of commercial products that can do this, but not with the flexibility I wanted. I designed a Arduino micro-controller based solution that is very

This electronic instrument allows you to sequence and loop audio and MIDI data. Most of the time I use it to sequence drum samples so I can play around with different beats and rhythms. The really great thing about this instrument is that it is very portable, it fits in your hands easily, runs off

The Freetronics LeoStick is a handy break-out board for the ATmega32U4 microcontroller. The board has a convenient USB stick format, and is based on the pinout and connections of the Arduino Leonardo reference design for compatibility with the Arduino IDE. Before you plug in your LeoStick for the first time please read this section of the

In our previous two tutorials (see here and here), we created a Simon-type game using the Arduino, a hardware platform for simple, and not so simple, electronics projects. We placed three buttons and three LEDs on to something called a breadboard, and wrote a small program that would send a random sequence to the LEDs,

In part 1 of our Arduino tutorial seres we covered the basics of how the Arduino works, and we’re going to use that knowledge in a hands-on project and see how this open-source hardware programming environment works when we’re actually trying to get something done with it. After this, you’ll have more than enough information

Arduino is cool. It’s cool because it’s a tiny device – about three inches by two inches – that comes with a USB port and a programmable chip. It’s cool because you can program it using a very simple programming language known as Wiring. But most of all, it’s cool because the entire reference design

This instructable will show you how to make an RC launch system for your Estes rocket, which can be operated with a TV remote. What it does is it allows you to press the center button on your TV remote, and it’ll automatically launch your rocket. In this way it is basically a wireless version

A quick introduction to the Arduino Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling

INTRODUCTION This manual will show you how to use each of the components in the kit, and give you software Sketch examples for each one. Then you can combine some components to make examples of Automatic Systems such as a lighting controller. You’re probably here because you’re interested in MAKING things with Arduino. The

This tutorial will show you how to make a thermal cycler from scratch for about $85. In short, PCR (polymerase chain reaction) amplifies bits of DNA, creating millions of copies of a target sequence. You can use it to test a DNA sample for a specific gene, for instance, to check for genetic modification in
