I'm new here and I needed your help.
I started a project that involves controlling an aquarium.
I have a mega arduino and an RTC to control the aquarium but wanted to add a button to be able to connect the led together with the RTC
Can anyone help?
RTC (Real Time Clock), connect with LED?
Could you please elaborate what it is your are trying to do (control), what you have provided is not enough information.
What ‘exactly’ are you trying to do?
Show us a good schematic of your circuit.
Show us a good image of your wiring.
Give links to components. Posting images:
