Spinning Tardis with blinking LED (Powered by littleBits) using Arduino

Step 1: Gather all needed parts.

LittleBits:

· (2) Wires

· (2) Power supplies

· (2) 9v Batteries and Connectors

· (1) littleBits Arduino Board

· (1) LED

· (1) DC Motor with the Motormate

Equipment:

· Scissors

· Tape

· Glue

· Tardis template

· Construction Paper

· Dome (to diffuse the light at the top) – designed and 3D printed specifically for this project (file attached). You can also use a clear push pin if you’re not able to print the dome.

· Box Cutter

Step 2: Print the Tardis template

We recommend that you enlarge the template before printing; this will give more room for the component for fit together in the box. Glue the printed template to the construction paper. Use the box cutter to cut lines in the template where white lines occur over the black tabs; these are notches where the labeled tabs will enter. After the notches have been cut, cut out the outline of the template pieces.

Step 3: Connect the littleBits

Connect the littleBits parts as seen in the image. The motor and the LED should each have separate power supplies.

Step 4: Program the Arduino board

Spinning Tardis with blinking LED (Powered by littleBits) using Arduino circuit

Program the Arduino board using the blink sketch. Code below

for reference:

int led = 1; // Define the pin the LED is plugged into

void setup() // Initialize setup

{

pinMode(led, OUTPUT); // Define the LED as an output source

}

void loop() // Loops through the sketch

{

digitalWrite(led, LOW); // Turn off the LED

delay(1000); // Delay for 1 seconds

digitalWrite(led, HIGH); // Turn on the LED
