38kHz IR Transmitter Module

This module sends 38 kHz infrared signals via a 940 nm IR LED. It can be used to control devices with an infrared remote control, such as TVs, air conditioners or LED strips, from an Arduino or ESP32. The matching codes can be read beforehand with the IR receiver. For Arduino, the IRremote library is available.
