I'm trying to make a simple IR circuit that energizes a coil when the detector "sees" the beam (refer to attached schematic). The problem is when the everything is active, I have almost no current at the coil. Why am I losing so much current? I suspect it's because the base of the NPN transistor...
I'm working on a project for school, it's basically a IR controlled fan with 9V DC. Basically you press any button on a tv remote and the IR sensor ( TSOP 1838) picks up the signal and outputs it to the fan and the fan spins. Problem with this is I have to continuously keep a button pressed on...
