ATtinyX5

The ATtiny25, ATtiny45 and ATtiny85 (and ATtiny13a) are the smallest AVR chips and they are all pin compatible. It is an easy and inexpensive way to get started. I created a basic breakout board and some projects to demonstrate how to program these small, but powerful chips.

Breakout Board

board

Breakout board for ATtiny25, ATtiny45 and ATtiny85 (and ATtiny13a). It has a 6-pin ISP header, all the data pins are lined-up for easy usage, reset button, and JST power. You can use a bridge to put a resistor on each data pin (0-4).

LED Projects

bridge

The bridge connects the breakout board with the actual project. It puts a resistor on each data pin. All of the LED projects need a board and a bridge.

led5

Similar to the original MiniPOV - 5 LEDs connected to all the data pins. Great to learn about programming and just debugging of some code.

led20

20 LEDs Charlieplexed.

hex3

19 LEDs Charlieplexed.

TV-B-Gone

This simple shield turn the board into a full-fledged TV-B-Gone.
