This Instructable will show you how to build your own Web Connected Robot (using an Arduino micro-controller and Asus eee pc). Why would you want a Web Connected Robot? To play with of course. Drive your robot from across the room or across the country, using nothing more than Skype and a web browser (nothing […]

This instructable will help you to build an Arduino Binary Clock. The orignial idea for this instructable was designed by Daniel Andrade. My instructable uses surface mount components, but can easily be adapted to through-hole components if you wish. You can follow my other Instructable for Building Your Own Arduino to get started. I would

In this Instructable, I will step through controlling the temperature of most kitchen appliances. As an example, I will use an old Westbend Poppery popcorn maker (aka. coffee roaster), but these same techniques will be applicable to most hot plates, coffee makers, and waffle irons. This instructable puts you at risk of electrocuting or burning

This Instructable will show you how to modify an Altoids tin for a wireless 2×16 character display. Using an Altoids tin was inspired by the need to have a small yet protective enclosure for a pair of Xbee modules recently bought from Sparkfun. I purchased the Xbee Pro modules with external antenna for the extended range

This instructable will show you how to read the number on a binary pushwheel or thumbwheel switch using LED’s or an AVR microcontroller (I’m using an ATmega328p but this can be adapted for any AVR or probably another microcontroller of your choice). Multiple thumbwheel switches can be strung together to make an electronic combination lock,

RFID is the craze, found everywhere – from inventory systems to badge ID systems. If you’ve ever been to a department store and walked through those metal-detector-looking things at the entrace/exit points, then you’ve seen RFID. There are several places to find good information on setting up RFID, and this instructable focuses on installing the

The other day I was wanting to check on one of my AVR‘s but I was upstairs and god knows it was too much of a hassle to go downstairs to where the microcontroller was. But, there were two idle computers sitting upstairs next to my lazy butt, so I had a half-day from work

With a single LED you can indicate the state of something: on or off. That might be a little boring. With an array of LEDs you can display characters or even some simple blocky graphics. That might add a little pizzaz to a small microcontroller project. You could use individual LEDs wired into a grid

Inspired by various LED Throwies, blinking LEDs and similar instructables I wanted to do my version of an LED controlled by a microcontroller. The idea is to make the LED blinking sequence reprogrammable. This reprogramming can be done with light and shadow, e.g. you could use your flashlight. This is my first instructable, any comments

This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and
