In this instructable i will be showing how anyone can turn something with lights into a programmable arduino flashing lights or "Moving Lights"
Step 1: Gather Your Sign and Simple Resources!
First, find the sign you would like to be able to easily program.
For this Instructable i used a arrow sign that just turns on and off.
You will need your standard Arduino Uno and helps to be attached to a breadboard and a
power source of you own, this can be a wall plugin or some batteries.
you will also need male wire jumpers. i needed 7 for this project.
Step 2: Remove, Cut, Untangle
Next, remove the back of whatever sign you have and find the wires
next, cut each wire so all the lights just have two cut leads coming from the lights.
it helps to single these wires out by untangling them.
Step 3: Attach Jumper Wires
so make plugging into the Arduino and breadboard simpler, we will solder the ends together and attach electrical tape to prevent wires from touching on the conductive point.
Step 4: Attach Arduino and Battery
Using sticking two sided Velcro, attach the Arduino and power source to the backside of the sign!
Step 5: Connect the Pins
Next, attached all your negative leads to the ground in the breadboard, and attach a pin to the ground of the Arduino and the breadboard so all the lights are grounded.
Next, give each light a digital female end and and attach the male pin to it.
(I put mine in order from left to right, so i put the far right light pin 2, and the one next to it 3 and so on...)
Step 6: Arduino Program
This program is super simple, its basically a loop, mine has a switch to turn on and off, otherwise if you have a loop you can just disconnect the power source :-)
Step 7: Enjoy and Place Somewhere Appropriate :-)
The program i wrote makes the lights create a arrow sign :-) you can program for them to do anything you want!! Good luck and enjoy!!!
