Here introduces a remote controller that consists of transmitting and receiving parts.Transmitting circuit is with LC2190 as the core, K1-K6 are coding switchs, C2 is a pulse interval timing capacitance. Modulated coding signal is outputted by IC1 ① pin, then be amplified by BG1, and be emitted by load infrared LED. The principle is shown figure 1.Receiving circuit is shown in figure 2. Encoding signal transmitted by remote controller is sent to LC2200 by IC2 CX20106, then LC2200 outputs control various ways load, A-F are related K1-K6 control output ends.
