Here are some pictures of my coop door opener. Its coming along… slowly. So far I have built the winch assemboly, the motor driver and the light sensor. I have some code done, but I’ve been having issues with using the Arduino Time Library without syncing time. Here are some pictures of the build.
I’m really happy with the BBB freeduino I’m using for this project. But I think next time I’ll just make a custom ‘Roboduino’ pcb.
Here is a schematic if you’re interested.
This is the motor driver wiring.
The light sensor uses a photocell and a 330 Ohm resistor.
Here is the actual winch that will pull the cable that lifts the door. Its built from a cd-rom drive, legos, and plywood.
