Led Sign

The two of us have no experience in Arduino, design, and engineering in general. We wanted to find a simple project that would teach us the basics, but still be fun. Our teacher, Ms. Berbawy, had an example of a previous student who created an LED sign, but it had to be plugged into the wall. We were inspired by this project, but wanted to make the LEDs battery powere.

Step 1: Step 1: Upload Code to Arduino Sketch

We followed the book Arduino Project Handbook by Mark Geddes to create our project. We downloaded and uploaded the PoLoLuLedStrip to the Arduino Sketch. We then adjusted the code to our project. We used 32 LEDs and pin 12.

Step 2: Step 2: Use 9V Batteries to Power

The packing on the LED lights packaging explicitly state to only use a 5V battery, but when we used that the lights were very dim. We used a 9V battery instead, and because the Arduino regulates it to 5V, it was fine.

Step 3: Step 3: Design Box for Laser Cutting

We used Illustrator to design our logo. The cutting lines are red, rasterizing is black, and carving is blue.

Step 4: Step 4: Attach LEDs to Arduino

We first soldered wires to the LED strip. Then we put the wires in their proper spot in the Arduino.

Step 5: Step 5: Assemble Everything

Make sure all the wires are in the right spot and the battery is plugged in. Glue the acrylic logo to the box. We also created a curtain to put on the back of the box to help further illuminate the lights.
