Holiday's are really fun when we decorate our place with lights and stars. LEDs are mostly used for this purpose. I have made a DIY video series for a decorative, fun LED Ferris Wheel. Try one for this Christmas!


Required Materials [with links to buy]:

  1. Metal Mechanix 5
  2. Jackly Screw Driver set
  3. DC Motor
  4. Jumper wires
  5. LED
  6. Drill Chuck
  7. Wire connector
  8. Arduino Uno/ Mega
  9. 9V Battery, battery connector  and USB Cable (for Arduino)
  10. Scissors, double-sided tape and insulation tape


This will also be my submission for Cool LED Display


Code [Arduino]:

int ledOuter = 12;
int ledOuter1 = 8;
int ledInner = 13;

void setup() {
  // put your setup code here, to run once:
  pinMode(ledOuter, OUTPUT);
  pinMode(ledOuter1, OUTPUT);
  pinMode(ledInner, OUTPUT);
  pinMode(A1, OUTPUT);

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(ledOuter, HIGH);
  digitalWrite(ledInner, HIGH);
  digitalWrite(ledOuter1, LOW);
  analogWrite(A1, 255);
  digitalWrite(ledOuter, LOW);
  digitalWrite(ledInner, LOW);
  digitalWrite(ledOuter1, HIGH);
  analogWrite(A1, 100);
