I have an DS3231 and I want to turn on an Arduino every day. Alarm on the DS is pretty simple and works. But the SQW Output goes to LOW when Alarm is active.
I want to build a switch which turns on everything when the Alarm starts and uses as less as power as possible when turned of. My Project is drawing 2A Power, so this should also be considered.
Should I use an Relay, Transistor, P-Mosfet, Opto.... and which one and with which scematic... Sorry i am a bit lost in this Transistor and Co kind of stuff
Thanks in advance.
