001d_Buttons
Project Overview:
Create a project that can make the Arduino turn on an LED with the push of a button. For this assignment I will be using a tactile push button and a pull down resistor.
Code:
int btn2 = 2;
int led = 9;
void setup() {
pinMode(led, OUTPUT);
pinMode (btn2, INPUT);
}
void loop() {
if(digitalRead(btn2) == HIGH){
digitalWrite (led, HIGH);
}
else{
digitalWrite (led, LOW);
}
}

What I learned / Problems:
What I leaned:
- I learned how to wire a pull down resistor with a push button.
- I also learned to get input from a push button.
Problems:
- None
