At present, the quantity of TV, VCD, VCR etc infrared remote control emitters is increasing. This design of the circuit aims at their performance, making the remote control emitter to exert another purpose: emit infrared signal, control lighting lamp and the control distance is >8 meters.Circuit principle: This infrared control switch circuit is shown in figure 1, which mainly consists of infrared receiving end and IC4069. When the infrared receiving end is static, the circuit outputs high level. When the circuit receives infrared pulse signal that is sent by remote control emitter, tail edge outputs low level (pulse signal).
