BACKGROUND: I am developing a circuit that uses an infrared LED emitter/detector pair to synchronize a strobe effect with an LED. It's for strobing an animation toy (a phenakistoscope- the toy is a cardboard disc with slots cut in the outer edge, creating control of the IR on/off as it spins.)
I'm also using an NPN (2N2222) as a switch, have resistors, and am using a 9v on the "detector & LED" side. The "emitter" is on a separate circuit.
QUESTION: I'm trying to incorporate a larger array of LEDs to create a brighter light for a larger disc. The circuit I have works okay if the on/off is slow (disc spins slowly), but the LEDs barely light up when the disc spins faster.
Could someone please look at my circuit and offer suggestions / insight, please?
thanks-
