This program will read from one ADC channel an analog value or voltage generated by a potential divider made by a 3.3 K resistor and a LDR. One end of 3.3K resistor is connected to 5V and other end to ...

Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...
