hello, i need little help
i put some part on a circuit board
(arduino, receiver, magnetic switch…)
http://www.bilder-upload.eu/show.php?file=630997-1436849955.jpg
the L293 isnt connected, i want first test
the switches.
i change the psu to this one
http://www.amazon.de/Netzteil-Iomega-CDRW55292EXT-CD-RW-Extere/dp/B00K7EKK7W
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?
