Tell us about yourself!
so i got the hardware working. Can u be awesome and write some code for me. :P. I got a DPDT relay. (It switches the power between 2 sources when u supply 3.3 volt). The relay should be swiched for 2 min and then be switched back. Can u help me with this? It should be automaticly switched at a certain time of the day. Like 12am. Thanks in advance.
Ive got a few questions. Can this be done the same way with a 5v pump and a 5v relay? I got a 5V DPDT relay laying around. Can i use that?
