What is a Circuit?
What are Resistors?
conversion calculator resistor color code
Light-Emitting Diodes (LEDs)
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
int switchPin = 8; int ledPin = 13; boolean lastButton = LOW; boolean currentButton = LOW; boolean ledOn = false; void setup() { pinMode(switchPin, INPUT); pinMode(ledPin, OUTPUT); } boolean debounce(boolean last) { boolean current = digitalRead(switchPin); if (last != current) { delay(5); current = digitalRead(switchPin); } return current; } void loop() { currentButton = debounce(lastButton); if (lastButton == LOW && currentButton == HIGH) { ledOn -= !ledOn; } lastButton = currentButton; digitalWrite(ledPin, ledOn); }
