Let's turn it up a notch and upgrade project #1 by adding more control!
Things you’ll need:
-LED
-10K resistor
-pushbutton
-Arduino UNO
-Breadboard
-Cables
Code:
const int LED =13;
const int BUTTON=7;
int val=0;
void setup() {
pinMode(LED, OUTPUT);
pinMode(BUTTON,INPUT);
}
void loop(){
val=digitalRead(BUTTON);
if(val==HIGH){
digitalWrite(LED,HIGH);
}
else {
digitalWrite(LED, LOW);
}
}
