The transmitter module is based on NE555 infrared transmitter module. 38KHz carrier circuit board produced by the NE555, no
MCU’s PWM pins to reduce the corresponding code, reducing the burden on the MCU. SIG module pin is high, the module will
send an infrared signal of 38KHz, SIG pin is low, the module will stop sending infrared signals. The infrared receiver
module based on integrated infrared receiver head.The infrared receiver module and transmitter module can complete the
infrared remote control with the codec program.It can receive the modulated infrared signal of 38KHz that is sent by the IR
transmitter module and demodulate it into logic level, ie, when it gets the modulated infrared signal, it outputs one
negative pulse and returns to normalcy (High level). The infrared receiver module and transmitter module can complete the
infrared remote control with the codec program.
