How to use Arduino?
1. Arduino Script
* * Zalan's first Program */ int ledPin = 13; void setup() { //initialize pins as outputs pinMode(ledPin, OUTPUT); } void loop() { digitalWrite(ledPin, HIGH); delay(1000); digitalWrite(ledPin, LOW); delay(1000); }
2. Arduino Script
int LED = 12; int BUTTON = 4; void setup() { pinMode(LED,OUTPUT); pinMode(BUTTON,INPUT); } void loop() { if(digitalRead(BUTTON) == HIGH) { digitalWrite(LED,HIGH); }else { digitalWrite(LED,LOW); } }
3. Arduino Script
