Overview:

In this experiment, we use the analog port A0 of SUNFOUNDER MEGA2560 to read the resistance of photoresistor after processing by the master control chip built-in ADC module, and display it on the serial monitor.

Components:

SUNFOUNDER MEGA2560 * 1

Photoresistor * 1

Resistor (10K Ohm) * 1

USB Cable * 1

Jumper wires

Steps:

First, connect the circuit

Second, program (Please refer to example code in CD we provide)

Third, compile the program

Fourth, burn the program into SUNFOUNDER MEGA2560 board
