LED Chaser

Here is a nice simple LED light chaser from the Hacked Gadgets Forum. There is a full schematic provided, I am not sure if the author will be providing the chip code however.

��4 functions triggered by the length of time control button is pressed.
1. Tap once to change patterns.
2. Press and hold for 0.5 seconds until 2 Leds start flashing then release. Unit will power off.
3. Press and hold for 1.0 seconds until 3 Leds start flashing then release. Unit will toggle between Continuous and Cycle mode. Continuous mode is the default and repeats the present pattern in a loop. Cycle mode automatically runs all the programmed patterns. Each pattern repeats 3 times before changing.
4. Press and hold for 1.5 seconds until 4 Leds start flashing then release. Unit will toggle between Bright and Dim mode. Bright mode is the default. Dim mode supplies less power to the Leds to lower their brightness level.��
