Infrared Receiving Module
The infrared remote controller shall be used in combination with the infrared receiving module. It is responsible for receiving the information transmitted by the infrared remote controller and decoding it into 16 codes
Tip
During the test, pay attention to the position of the infrared remote controller and the infrared receiving head to ensure that the infrared receiving head can well receive the signal transmitted by the remote controller. From the test results, it can be seen that each key has its own hexadecimal code. If you hold down a key for a long time, ffffff will be displayed in the serial monitor window
