AVR Mask1 is a led mask built around 74hc595 shift register and 8×8 led matrix.
The “Dylan Dog” comics decoupage, in conjunction with his stands, make it good looking.
t has 4 8×8 led matrix, 2 for the mouth, and 2 for eyes.
When the user get closer to the mask, the IR sensor placed on the back activate the mask.
If activated, it randomly runs eye and mouth patterns.
Patterns can be programmed in code, the patterns are just array of bytes, 1 stands for led on, 0 for led off.
We need 8 bytes to make 1 pattern for 1 led matrix (8×8).
If the user speak a small mic detects his voice, and execute the mouth speaking pattern.
Voice and proximity trigging could be setup using even an external variable resistor.
I’ve built this mask some years ago, but i’ve submitted it this year, at the “InverArt 2013” art fair, and kids goes crazy for it 🙂
This project is developed on Eclipse, built with avr-gcc on Atmega8 @ 8MHz.
