tinyDriver is a breakout board for the Atmel ATtiny84 chip, which comes integrated with a motor driver chip and an RGB LED. The idea was to create a convenient platform that can be used to understand microcontrollers in depth, by studying the datasheet and making use of the various features of the chip such as timers, PWM, interrupts, ADC, and digital I/O. The free and cross-platform avr-gcc and avrdude toolchain combined with cheap USB based AVR programmers makes it very easy to develop projects for this board. You can use tinyDriver as a convenient platform to learn about tinyAVRs and prototype your projects.
