Arduino Programming Language

Arduino uses a simplified version of C/C++. Every Arduino program (called a sketch) has two main functions:

void setup() {
    // Runs ONCE when Arduino starts
    // Configure pins, initialize settings
}

void loop() {
    // Runs FOREVER (repeating)
    // Your main code goes here
}
