LED CONTROL VIA BUTTON

Thanks to Dario for the soft switch. It works perfectly fine. I like how squishy of the switch. The circuit is pretty simple. I use “INPUT_PULLUP” for the switch. It’s a quick tip for all buttons 😀

LED CONTROL VIA BUTTON CODE

/*
Button

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 = 8; // the number of the pushbutton pin
const int ledPin = 7; // the number of the LED pin

// variables will change:
int buttonState = 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);
}

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

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

MARCH OF LEDs

It is tricky to make each of them light up when I press my switch. I have to make the specific states for them to light up in order. It’s pretty fun and cute with 3 LEDs with Red, Yellow and Green.

MARCH OF LEDs CODE

/*
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.

MIDTERM IDEA

I want to make one big squishy doll that can emit some lights through its eyes by dragging the tail. It could be really cute! The technique I use is going to be wool felting.
