Hi! I'm using the connections from the arduino shiftout example, but I've got a problem sometimes when the arduino starts all outputs go high. I'm controlling 10 tip122 with a solenoid 12v based lock so this is a big problem as it could open all the locks, I can't seem to find any way to start all …

DrDiettrich:
The pulldown resistor goes to Gnd, not to the output pin.

this is my current breadboard layout
