The program uses the analogRead() function to read the analog input value, and the input value range is between 0 to 1024. Then use the analogWrite() function to change the LED light duty cycle, and the duty cycle range is 0 to 255. Remap the range by using the map() function. | The program uses the analogRead() function to read the analog input value, and the input value range is between 0 to 1024.
