	Infrared Counting Circuit 1 Digit PUBLIC A functioning counting circuit. While the space between the IR LED and the IR Phototransistor is unblocked the number stays. When blocked, it increments by one. by lucasmoten | updated May 20, 2012 311   7414   7447   7490   count   infrared   led
	Light Sensitive Counter Circuit PUBLIC A possibly complete light sensitive counting circuit with 3 digits making use of 311, 7414, 7490, and 7447 ICs and 7-segment displays. by lucasmoten | updated May 15, 2012 311   7-segment-display   7414   7447   7490   de-bounce   digital   led   phototransitor   schmitt-trigger
