LED Hanukkah Menorah

Step 5 Source Code

Update: board files and code are available here https://github.com/szczys/LED-menorah

I have written the source code so that it performs in this manner:

• Plug in the power and the device starts up, lighting the Shamash (candle in the middle).
• Each button push lights an additional candle from right to left, allowing for the prayer to be said before the next candle is lit.
• After about 1 hour the lights will "burn out" when the device goes into power down mode. In this state very little power is consumed and the device will wait until the next night of Hanukkah.
• One button push will wake the device up from sleep and light the Shamash.

This source code is written in C for the avr-gcc comiler. I have also included a HEX file that can be burnt directly to a tiny13 without the need to be compiled.

The ATtiny13 uses the factory fuse settings:
hfuse: 0xFF
lfuse: 0x6A
