SunFounder ESP32 Starter Kit
When you press a button on the remote control, the infrared receiver detects the signal, and you can use an infrared
library to decode it. This decoding process allows you to obtain the key value associated with the button press.

Note:
• Open the 5.14_ir_receiver.py file located in the esp32-starter-kit-main\micropython\codes path,
or copy and paste the code into Thonny. Then, click “Run Current Script” or press F5 to execute it.
• Make sure to select the “MicroPython (ESP32).COMxx” interpreter in the bottom right corner.
• Here, you need to utilize the libraries found in the ir_rx folder. Please ensure they have been uploaded to the
ESP32. For a comprehensive tutorial, refer to 1.4 Upload the Libraries (Important).
