Circuit Diagram


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 == LOW) {
// turn LED on:
digitalWrite(ledPin, HIGH);
Serial.println(“switch has been triggered”);
} else {
// turn LED off:
digitalWrite(ledPin, LOW);
//Serial.println(“switch has been off”);

My Thinking

It was a very interesting experience making a wand that can simulate the special effect in the Harry Potter Movies, I just need to wave the wand, the LED will light up, which is very similar to the “Lumos” spell in the movies. If i can make it the next time, i will make a 3D printing LED diffusor so that the light will diffuse wider so the effect will be more beautiful.

And if it is possible, i will try to use 3d printed mold to cast a resin wand, which is able to hide everything perfectly.
