Arduino Blink All Pins
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.

// Pin 13 has an LED connected on most Arduino boards.
// Pin 11 has the LED on Teensy 2.0
// Pin 6 has the LED on Teensy++ 2.0
// Pin 13 has the LED on Teensy 3.0
// give it a name:
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
for (int led = 0; led < 20; led++)
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
for (int led = 0; led < 20; led++){
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
}
delay(1000); // wait for a second
for (int led = 0; led < 20; led++){
digitalWrite(led, LOW);
}
delay(1000); // wait for a second
