For all intents and purposes my LED light controller and LED strips, mounted in the channel are completed and done in my bedroom. I’ve learned a lot about electronics and programming the Arduino microcontroller, and gotten a lot better at soldering electronics.

While not my final project, and I’m hesitant to declare it fully done and forever on changing, it works, is semi-permanently mounted to the wall, and I don’t envision much in the way of changes for now. I do need to tweak the code to avoid remote button bounce (reading the signal multiple times due to my finger lingering on the buttons for too long) but for now I’m happy with the way it works.

Probably my biggest disappointment with the final product is the disappointing brightness of the LEDs. They are supposed to be able to put out 15-20 lumen per LED at 12 volts with a 100% duty cycle. They don’t do nearly that much light, I ended up building a third strip to bring the 1/4 watt LED count up to 480, or three double 1 meter strings. At full brightness, that means they will use upwards of 120 watts in total, and should be upwards 7,200 lumen output but I doubt I’m actually getting even 1,600 lumen which is what a standard 100 watt bulb puts out. That said, rarely do I ever drive all channels at 100%, and indeed that’s not recommended for a long life with the LEDs. The power supply has some voltage drop, which further reduces the wattage put out and I’m not sure if the transistors are operating at full saturation, as I might have too big of a resistor protecting the Arduino. I was a bit confused about that point based on the spec sheet for the transistors I purchased.

I decided to leave the wires bundled with wire ties draped along the walk rather than use plastic romex to hide the wire. I figured that the colored wires were pretty and I have no reason to hide them. Although I do have to say they do look a bit sloppier then I would like just hanging down with cable ties. It kind of reminds me of a wiring job by a farmer or in a Bodega. But they are low voltage and are properly connected per standard with soldered connections and heat shrink, so any messiness is just visual.

I’m glad this project is done so I can move forward with other ones.
