Zack shared with us his simple ATTiny85 Arc Reactor project:
Something I was making for Halloween. It has a potentiometer that you turn to switch the mode of the LEDs from flicker, pules, or solid. I used an arduino to program the ATTiny85. Ones I finished it I ended up giving it to a friend so I am not 100% sure on the capacitors. Anything close to 450uF should be fine and depending on the power supply you may not need them at all.
- 2 resisters (10 Ohms hook to LEDs and 470 Ohms hooked to potentiometer)
- 10k Ohm Potentiometer
- LM7805C 5 volt regulator
- 2 small Capacitors (I think I used 450uF)
- ATTiny85 and 8-Pin IC socket
- PC Board terminal
- 8 white LEDs
- Round ProtoBoard
