The IR diode's flash rate is determined by the value of C1, a 220-μF capacitor that sets the rate of oscillation at 1 Hz per second. Reducing C1 will increase the frequency of the circuit, while larger values will decrease the frequency. Because the circuit only sends out single, nar-row pulses of invisible light, the IR receiver only responds with a click for every output pulse.
