“Flying Saucer” Step 1. Wire the Arduino

- - - -

Materials Required 1x Arduino 1x Breadboard 1x Photocell 1x 10k Ω Resistor 8x 100 Ω Resistors 8x LEDs (red) 20x Connectors/Wires *Don’t have a breadboard? You can always use solder to make the connections which eliminates the breadboard.

*Want to be stand-alone? Add an onboard 9V battery or 3 AAA batteries to your setup and eliminate the USB cord.

“Flying Saucer” Step 3. Construct the UFO

- - - -

Materials Used - 4 Clips - 2 Plates - 1 Dixie cup - Paints - Scotch Tape

- - - -

Feel free to get creative on this step. Once you’ve created a UFO case that suits your fancy, insert the

Arduino components, tape them down (as desired), and clip the two plates together to conceal the components.

BE SURE TO KEEP THE PHOTOCELL ON EXTERIOR!
