Mostly populated
10/24/2016 at 13:32 • 0 commentsI've mostly populated the board and it works!
- Ended up replacing the power supply diode with a wire since I was having trouble with it. Will just be careful.
- Ended up leaving the reset button circuit unpopulated. Will just use the power switch.
- Haven't populated the transistor for the focus button switch. Will do that so the program can wake the camera before firing the shutter release.
I just need to design a case.

Tested on breadboard
08/30/2016 at 12:20 • 0 commentsI've wired everything up with my Atmega328P on a breadboard, including:
- 9V power supply through regulator
- connection to LED panel
- shutter release trigger to 3.5mm jack
- rotary encoder
The encoder doesn't seem to work reliably, but I'm pretty sure it's a software problem. It's configured with INPUT_PULLUP in the code, and is connected to ground in the encoder itself, so it's probably not a voltage problem.
One thing missing so far is an interface to analog input. I may just wire that directly later. Just want to keep it simple for now.
I've put in an order to DirtyPCBs, but I named the files wrong in the ZIP. We'll see if that causes a problem.
