Connection for 2560 R3:
Sample Code
After wiring, let's begin the program compiling. The program is similar to the PWM.
For change detail, please refer to the Sample Code below.
//////////////////////////////////////////////////////////
int potpin=0;// initialize analog pin 0, connected with photovaristor
int ledpin=11;// initialize digital pin 11, output regulating the brightness of LED
int val=0;// initialize variable va
void setup()
{
pinMode(ledpin,OUTPUT);// set digital pin 11 as “output”
Serial.begin(9600);// set baud rate at “9600”
}
void loop()
{
val=analogRead(potpin);// read the analog value of the sensor and assign it to val
Serial.println(val);// display the value of val
analogWrite(ledpin,val/4);// turn on the LED and set up brightness
（
maximum output value 255
