Can someone confirm my plan is correct before I burn my house down?
- pi +5v to relay module VCC
- pi gnd to relay module gnd (is 3v3 enough?)
- pi gpio1 to relay module In1
pi gpio2 to relay module In2
12V+ battery pack to relay module middle connector for the rele (com?)
- simple wire from NO connector in the rele to the solenoid
- simple wire from solenoid to 12V- in battery pack.
And same approach for 12V led stripes and other 12V stuff.
This would be the schematic, please confirm I didn't omit something when drawing it.
Is that Ok ???
