Study Notes
Arduino Sketch for Controlling an Output Pin
- The code defines variables for the output pin (
pin_o
: 13), the input pin (pin_i
: 1), and the state of the input pin (State
). - The
setup()
function configures the output pin as an output and the input pin as an input. - The
loop()
function reads the state of the input pin (pin_i
) usingdigitalRead()
. -
State == 1
indicates the input pin is HIGH (pressed), andState == 0
indicates it's LOW (released). - If the input pin is HIGH, the
digitalWrite()
function sets the output pin (pin_o
) HIGH, turning the LED on. - If the input pin is LOW, the
digitalWrite()
function sets the output pin (pin_o
) LOW, turning the LED off. - This code demonstrates a basic but effective implementation of using a pushbutton to control an LED.
