Thank You guys upfront you have help me along the way on this project. This is a great forum with very knowledgeable members
I have two relays that I need to trigger on and off at various times during the day. The clock os working and I am reading thur the serial port. Both relays are working on and off. I am using an esp32 as a micro controller and the Arduino IDE as the language. I am having trouble getting the triggers in the code I am really lost on this. Please help me set these triggers up. Thank You for the help
