Hello, all
I am a complete newbie, so please bear with me!
I am trying to make an automatic control system for a 12 vdc linear actuator. The actuator is used to close and open a sliding door on a chicken coop. The actuator has an integral stop switch so that when it reaches the end of its limit for travel it automatically shuts off. So - in the morning an AC timer will supply current to a 12vdc adapter, which will send current to the extended actuator, which will contract and open the door. When the actuator is completely contracted it will turn off in response to its integral stop switch. At dusk, the timer will turn again and - if I have put a device in place that will reverse the polarity of the DC current - the actuator will extend and close the door. It will repeat the process every 24 hour.
The problem is the device that will reverse the polarity of the DC current automatically. How do I create it?
THANKS!!!
