Arduino Pro
  • There are no digital input pins 11,12,13 and 17 available on the controller board.
  • Digital pin 2 is SDA and Digital pin 3 is SCL which supports I2C communication.
  • Digital pin 16 is MOSI,15 is MISO and 14 is SCLK (or SCK) supports SPI communication.
  • The AREF input does not exist on the board.
  • The Analog pins(A0,A1,A2,A3) can also be configured as digital pins(D18,D19,D20,D21).
  • The Tilt sign(~) represents the PWM pin.

How to program Pro Micro?

Hardware and Software Required

  • Arduino Pro Micro(5v model used here)
  • Arduino IDE 1.0.6V

Program for Arduino Pro Micro

Like other Arduino,the Pro micro has no on board led.So we need to connect a led externally to the Pro micro board.Before uploading code to the board,select the board under tools menu as Arduino Micro.

void setup() 
{
  pinMode(2, OUTPUT);// initialize digital pin 2 as an output.
}
void loop()// the loop function runs over and over again forever 
{
digitalWrite(2, HIGH);   // turn the LED on (HIGH is the voltage level)
delay(1000);              // wait for a second
digitalWrite(2, LOW);    // turn the LED off by making the voltage LOW
delay(1000);              // wait for a second
}
