• Here you need to use the library called lcd1602.py, please check if it has been uploaded to ESP32, for a detailed
tutorial refer to 1.4 Upload the Libraries (Important).

3.32 5.14 IR Remote Control
An infrared receiver is a component that receives infrared signals and can independently detect and output signals
compatible with TTL level. It is similar in size to a regular plastic-packaged transistor and is commonly used in
various applications such as infrared remote control and infrared transmission.
In this project, we will use an infrared receiver to detect signals from a remote control. When a button on the remote
control is pressed and the infrared receiver receives the corresponding signal, it can decode the signal to determine
which button was pressed. By decoding the received signal, we can identify the specific key or command associated
with it.
