ATTiny85 PIR LED controller
A simple LED strip controller using a cheap PIR module and an ATTiny 85, when motion is detected the LED's fade on gracefully, the LED's will stay on while the PIR detects motion, if theres been no motion for 30 seconds the LED's fade down to off.
Input is 12V however theres no reason this couldn't run a 5V LED strip as the board has a voltage regulator on board to step down to 3.3V for the ATTiny.
