Did I ever say movies are a great source of inspiration for my projects? I think I already said... and this is one more. This PCB is inspired by the movie Back To The Future, of which I am a huge fan. A long time ago I thought about making a flux capacitor... I saw several videos and projects of people creating some perfect replicas... but I decided to start with a simple board.

This was also the first board designed by me... and as a beginner, I used Fritzing to develop it. As I didn't have much experience at the time, the board has its little flaws.

ATTENTION: if you are going to make this board, protect the USB connector of the Arduino Uno board with insulating tape or other insulating material, to prevent shield connectors from touching the USB and causing a short.

To assemble each PCB, I only needed the following components:

• 3X 220 ohm resistor;
• 9X 3mm LEDs;
• male pin header;
• 2X push button.

I made a simple code to test the shield, that is available to download here: https://bit.ly/2lPRHeM

I still have to code the two push buttons. The idea is to increase/decrease the "flux" (the speed of the blinks) while pressing the push buttons.

Great Scott!
