Starter Project EL Wire

For my starting project, I did an electroluminescent wire, also called an EL wire. An EL wire is a long thin wire that glows when an alternating current passes through it. For my project I created a connection from the transistor, the power source, to the actual wire itself. I soldered the wires together and tightened the whole connection with a heat shrink. It was a good but difficult experience, this being the first time I’ve ever soldered. It was also difficult to shrink the heat shrink, especially since I was doing it wrong at first. In the end, I finished my project without any critical errors the first time.

  1. To be more specific, pins 4 and 7 of the DPDT have been fed through a hole that was drilled and connected to the two terminals on the left of the board. This will allow one motor to the switched. The same process has been repeated for the other DPDT except they have been attached to terminal 3 and 4. This will switch the second motor’s direction. The 5th pin of the SPDT relay (furthest in picture) has been fed through another drilled hole and soldered to terminal 5. This will control the servo. The 6th terminal has been connected to the positive terminal (green curved wire). Next on both DPDTs pins 3 and 8 have been fed through a big hole drilled out and stuck together with heat shrink and connected to the positive terminal to supply power. Pin 5 on the two SPDTs (for the motors) and pin 4 for the servo SPDT have been connected to the negative terminal through another drilled hole. This will complete the motor circuit. The final connections made were from the motor/servo circuits, to the arduino microcontroller. By reference of an image of the uno, pins 2-6 were soldered to the resistors to join the arduino to the motors. Pin 7 was connected to what will be the white wire of the servo (or the left pin).The red pi of servo (centre) was connected to the 5V pin of the arduino and the black wire (right pin) was connected to the ground of the arduino. Finally, the other ground of the arduino was connected to the negative terminal. (to make reference to the relay pin numbers go to the picture below the bottom of circuit image.
