We finished our R, G, and B strips (each with about 45 LED’s), and we hooked them up to the bench power supply. We are feeding voltage through the breadboard, then through both the Arduino V-in, and through two adjustable voltage regulators (LM317) – then through three transistors. One goes to green and blue LED strips, which each ideally require about 3-3.5 V, and one goes to the red LED strip, which requires about 2.5 V.
Here we are testing the lights. It took us a little while to figure out how to get the brightness of each color to be more calibrated – since the red ones require less voltage, we realized we’d need an extra voltage regulator.
We got white glossy plexiglass which we will sand to look matte. With about 4’x4′ we should be set, although we have much extra. We will use AMS to cut out the parts for the light fixture (a box roughly 20″x20″x4″) and a box to contain all the switches, the arduino, the wiring, and the breadboards (roughly 35.5″x4″x4.625). I made the templates using Illustrator.
269 Canal street is a decent place to get parts. We got a power adapter that goes up to 5 Amps, so we should have enough with that to get the desired voltage and amperage for the LED’s.
