/*
Attempt to make a circuit design.
Idea is - push button and led lights
If button is lit, then turn led off.
/
Button is attached to the 5V and a 220 Ohm resistor to ground
Top of button is attached to pin 2 (input)
Led anode is attached to output pin 8
Led cathode is attached to 220 Ohm resistor to ground 
*/

  // Set constants and variables
const int buttonPin = 2;
const int ledPin = 8;

int buttonState = 0;

void setup() {
   // intialize pins and ensure LED is off
pinMode(buttonPin, INPUT);
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, LOW);
}

void loop() {
  // Read state of button
  if (buttonState == HIGH) {
    digitalWrite(ledPin, LOW);
} else {
    digitalWrite(ledPin, HIGH);
