arduino 0-5v input
Maybe – and it came to me because my friend asked me to he – wants to sell LEDs in the interior of his car and take out the old bulbs and he wanted blue. So I figured why not allow them to have every single color. So we got some of these red green blue LEDs. They have all three colors in them and we made this circuit that allows you to control the mixture of color, so you can get any color in the color spectrum, so here I’m gon na fart on the top. Here we have the red circuit or the red LED circuit, and we used two resistors here, because we were too lazy to find one that was the same size as these two I think they’re, like I don’t know, and then here we’re using these be JT’s. Here are switches, they’re, pretty small, I know, but that was just for a prototype will probably make them bigger later and they’re npn for sure, then we have these current, limiting resistor Zahn the BJT s just because we like to be safe and awesome, and this capacitor Is where the power is drawn? Well, it’s in parallel to where the power is drawn and it kind of serves as a low pass filter to limit the current or two to equalize any ripple going through the circuit. This potential owner has used to control the color of the LED, which is something I’m, not quite sure, I’ve, seen in any of the videos online, so that’s.
What I think might make this a little special it’s, not very hard, I’m sure a lot of people could do it. In fact, they probably have and then here’s a microcontroller that we using it’s an Arduino 28 pin hunk of Awesomeness. Ok, so here we go. We’Ll put this on to diffuse the light I’m gon na put two of these in here, which is probably not kosher, but I mean it’ll work so that we’ll just serve as a light diffuser, so you don’t all go blind. So here we have white. We kind of added white is a clause in our code, because white is pretty hard to obtain in the color spectrum and so give away. And then you start turning it and you get blue and it starts to slowly turn to green and then yellow through orange and to read and then through purple and that to blue, and you can go back through that and get back to what. If you turn this a little too much, obviously you’ve seen it there’s like a little blue flash when you hit the end of the wiper, I don’t know what the deal is with that will work on it, but no actually I think I’m.
