Hi.,
Am working on ULN 2003 and relay switching a simple device (buzzer).
When i tried to connect one of the collector pin (1C) of the ULN to the relay, the voltage becomes constant.
Without connecting to the relay the voltage varies but when connecting voltage becomes constant as said.
What's the bug here?
How could I fix it?
