Very new to Arduino. What resources would be good to look at for guidance on how to program an Opta Wifi to close two normally open relays every 60 seconds for a defined duration and remain accurate via NTP?
This is for an older 24v triggered flip clock which needs a bi-polar signal. Ideally, I would also be able to write into the code a way to keep record of the time which the clock is currently displaying. Thereby also allowing for an option to have "pause" and 'play" buttons which would stop the relays from closing while "paused" then bringing the clock back to accuracy when "play" is triggered.
Any suggestions are welcome. Appreciate communities like this.
Cool, but why a complex/expensive and poorly supported (forum) processor for this seemingly small project.
I would forget about the mechanical part, and first write code to display the local time (with DST) on a serial monitor. That would be a few lines of code for an ESP32, but I know nothing of the processor you're trying to use. After that I would think of adding the buttons.
DST for the flip clock can be done automatically, which was achieved in this project.
