// modify the esp32 simulation with a potentiometer
// and an LED attached to the GPIO16 (with a 470-ohm resistor),
// the LED lights up following the rotation of the potentiometer (starting from OFF to full 100%)
// using ADC and PWM reading techniques for LEDs
//
// share your link in the field in eLok according to the task given
// Enjoy your work.
