Arduino Week 3

Hi guys!

Below are the videos for my Arduino Week 3 work. This week’s stuff was tricky for me… not gonna lie. I feel that I am on the verge of a mental breakthrough with understanding how writing code works… but still trudging through the mental muck.

Digital Input

I got a little turned around with Becky’s mind games but both Digital inputs are here:

The Serial Monitor/Analog Input

Two Buttons Control one LED (on and off)

This was so tricky for me! But Tinker sphere was a great place to work it all through and I had some light adjustments when I built it out IRL, and the code isn’t too pretty but it’s working and that’s magic.

/*
  Button

 Turns on and off a light emitting diode(LED) connected to digital
 pin 13, when pressing a pushbutton attached to pin 2.


 The circuit:
 * LED attached from pin 13 to ground
 * pushbutton attached to pin 2 from +5V
 * 10K resistor attached to pin 2 from ground

 * Note: on most Arduinos there is already an LED on the board
 attached to pin 13.

// constants won't change. They're used here to
// set pin numbers:
const int buttonPin = 2;     // the number of the pushbutton pin
const int ledPin =  13;      // the number of the LED pin
const int buttonPinoff = 7;  //the number of pushbutton2 pin

// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status
int buttonState2 =0;    // variable for reading the pushbutton status

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT_PULLUP);
  pinMode(buttonPinoff, INPUT_PULLUP);
}

void loop() {
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);
  buttonState2 = digitalRead(buttonPinoff);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState == LOW) {
    // turn LED on:
    digitalWrite(ledPin, HIGH);
  }
  // check if the pushbutton2 is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState2 == LOW) {
    // turn LED on:
    digitalWrite(ledPin, LOW);}
}
