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);}
}
