[Steve] created an AVR programmer using an old USB keyboard. We feature a bunch of AVR programmers, but this one is made from parts that many people will have lying around. There are two components: ...

The project utilizes an open source Atmel AVR microcontroller while incorporating a state of the art USB programmer. The firmware of the USB programmer can work for almost any AVR microcontroller on ...

The USB in-circuit programmer for Atmel AVR controllers is termed as USBasp which consists of an ATmega48 or ATmega8 along with a couple of passive components. In the design, no special USB controller ...

If you want to program an AVR chip as inexpensively as possible, then [Ian’s] solution might just be for you. He built an AVR programmer using only four components. This design is based on the ...

Not just for nerds, anyone with an interest in electronics, computers, or engineering can build a circuit to blink an LED or read a temperature sensor. The NerdKit will walk you through building the ...

The AT90USB82 and AT90USB162 AVR microcontrollers from Atmel Corp. incorporate a number of performance features, including a full-speed (12-Mbit/s) USB controller. The AVR family of microcontrollers ...
