DIY Automatic Chicken Coop Door

I installed an automatic chicken coop door controlled by a timer. This design uses all 12V devices. The linear actuator has an automatic shutoff switch when it is fully extended or fully retracted, and draws a maximum of 3A. I used a 12V 4A power supply to power the system.
