SunFounder ESP32 Starter Kit
This project builds upon the 2.5 Number Display project by adding a button to control the digit displayed on the seven-
segment display.
The button is directly connected to IO13 without an external pull-up or pull-down resistor because IO13 has an internal
pull-up resistor of 47K, eliminating the need for an additional external resistor.
