This video demonstrates the use of GPIO pins on an ESP32-S3 development board. Specifically, it shows the utilization of GPIO 0 and GPIO 7. GPIO 0 is connected to the Boot button, while GPIO 7 features touch sensing capabilities. The screen backlight is controlled by reading the states of these two GPIO pins.
