This project is from Extreme Electronics that describes an AVR-based (Atmega8) remotely controlled fan regulator. The control commands are received through a DVD player remote control. With three buttons on the remote control, you can turn the fan On and Off and also conotrol the speed. You can also purchase the PCB for this project […]

“V-USB is a software-only implementation of a low-speed USB device for Atmel’s AVR® microcontrollers, making it possible to build USB hardware with almost any AVR® microcontroller, not requiring any additional chip.” For further details on V-USB and licensing, visit http://www.obdev.at/products/vusb/index.html This is a data logger project that reads an analog signal, converts into digital number,

The AVR ATXmega chip is a newer offering in Atmel’s AVR line. The Xmega is billed as a hybrid 8/16-bit MCU, which means you can use your normal development environment to program Xmegas (as compared to AVR32 and Atmel’s ARM line). Because the Xmega uses a different programming interface, it does require a programmer that

This instructable shows, how to do your own development board for Atmega16 or Atmega32 processors.The Internet is full of home made development boards, but I think that, there is room left for another one. This board have been very useful on my projects and I actually designed and made it to serve one of my

Use an attiny13a, two LEDs and a greeting card speaker to create a blinking Marioman that plays the Super Mario Brothers theme song. This can be an easy low-cost project for anyone who is looking for a fun way to break into AVR programming! The notes of the songs are generated by a square wave

There have been several Instructables dealing with outputs from the ATtiny2313 and similar AVR devices. For example, http://www.instructables.com/id/Ghetto-Programming%3a-Getting-started-with-AVR-micro/, http://www.instructables.com/id/Drive-a-Stepper-Motor-with-an-AVR-Microprocessor/. Working on the latest one from The Real Elliot, which showed how to control stepper motors, I found that it would be really helpful to be able to run alternate sections of code in the same

Halloween Robot controlled by an old wingman joystick. I don’t reccommend this for beginners with electronics only because some things like joysticks and power adapters are not all the same and must be modified. Additionally I provide programming code which will only be useful for particular stepper motors without modification. **This is still unfinished, but

The Joule Thief is such an easy and simple device, but what it does is amazing. It can use a battery that is not usable in any other electronic device and give it life again. It can even take a battery that won’t even power a basic LED by itself when it is brand new

When I was first working with AVR microcontrollers, I relied a lot on tutorials I found on the web, but nearly all of them raised the question of how to attach a programmer to the microcontroller when you aren’t using a development board. Most of the time, I would see people shoving pieces of wire into the

Have you played with Arduino’s and now have a taste for microcontrollers? Have you tried to go beyond Arduino but got stopped by the dense datasheets? This is the instructable for you! I was working on an instructable for the epilog contest which would wirelessly link two smoke alarms. I wrote all the code and
