hello, i need little help
i put some part on a circuit board
(arduino, receiver, magnetic switch…)
the L293 isnt connected, i want first test
i change the psu to this one
it has 5V and 12V at the same time
the systems runs
- receiver and send data works
- magnetic switches works als, i can see if one of the both
are opened or closed
but i ve now the problem, after some hours the system crashed
not pimatic / homeduino crash, the PI crashed.
what could be the reason?
