Particle Code Reference

This appendix will give you a basic understanding of different functions within the

Particle code, their correct syntax, return values, and a basic example of how to use that
function within your code.

Setup

This is a block of code that is executed only once your Photon board has booted up.

Example

void setup() {

//code is executed here only once
pinMode(D0, OUTPUT);
}

Loop

This is part of the code where it is executed repeatedly after the initial setup function.

Example

void loop () {

digitalWrite(led, HIGH);
delay(1000):
digitalWrite(led, LOW);

delay(1000);
}

This continuously turns a light-emitting diode (LED) on and off every 1 second.
