Description: Two push-buttons with 10k Resistors are used to turn an LED ON/OFF with an Arduino Nano.
Notes: When the left push-button (buttonPin1) is pressed down, the LED turns ON and in the Serial Monitor the value changes from 0 to 1. And when the right push-button (buttonPin2) is pressed, the LED turns OFF and in the Serial Monitor the value changes from 1 to 0.
Supplies:
1 – Arduino Nano
2 – Push-Buttons
2 – 10k Ohm Resistors
1 – LED
1 – 220 Ohm Resistor
Arduino Code:
int buttonPin1 = 4;
int buttonPin2 = 5;
int ledPin = 8;
int ledStatus = 0;
int buttonStatus1 = 0;
int buttonStatus2 = 0;
void setup() {
Serial.begin(9600);
pinMode(ledPin, OUTPUT);
pinMode(buttonPin1, INPUT);
pinMode(buttonPin2, INPUT);
}
void loop() {
buttonStatus1 = digitalRead(buttonPin1);
buttonStatus2 = digitalRead(buttonPin2);
ledStatus = digitalRead(ledPin);
Serial.println(ledStatus);
if (buttonStatus1 == HIGH && buttonStatus2 == LOW) {
digitalWrite(ledPin, HIGH);
}
if (buttonStatus1 == LOW && buttonStatus2 == HIGH) {
digitalWrite (ledPin, LOW);
}
}
