It's very satisfying to find purpose for unused components, and I was very happy with how it looked when I plugged it in.

The LED strip I had was actually so old that I couldn't use its sticky side and had to tape it in place, but this was fine because I could just keep the tape out of sight. While a 3d printed sign is cool, if you're following along and that's not your thing, there are plenty of other options for the same general setup using something like foam boards.Īdding the LED strip is just a matter of inserting it into the sign where it isn't directly in view. Thankfully, I had already printed it, which was more than a little convenient since my printer is all kinds of out of commission due to a tragic blob incident. The sign I used is a 3d printed sign I had designed. I waited until I was confident the project was fully complete before putting on the finishing touches, but it's a lot more fun to rock a custom light-up sign than it is a plain ol' LED strip so I went ahead and put the two together. The schematics are included in this project. This also requires a separate 12v power supply. In short, it uses Logic Level N-channel MOSFETs and 10k resistors to put together a simple breadboard setup that can safely connect the LED strip with the Arduino. It's an ideal setup, because it can put LED strips to use that aren't specifically made for Arduino, which is what I happened to have available. I referenced an article by 'makeuseof' for setting up the LED strip. With that, the capacitive touch aspect is functional, so it's time to make things bright and colorful! The TX pin is used to transfer information, and the RX pin receives it, so the setup is to use a jumper cable to connect the TX pin of the PSoC 4100s to the RX pin of the Arduino device.

Since we've setup the serial messages, we'll know exactly what to look for on the Arduino side. This was setup to send the values for Red, Green, and Blue (RGB) coloration from the color gamut, the color index we setup, and the brightness index.

I added the TX pin for UART in the pin tab, and added the code for sending the serial messages via UART. This can be very conveniently utilized by multiplying the index value by 51 to get values 0-255, where 0 obviously turns off the sign.įor the other aspects of the project that we'll get to momentarily, I utilized an Arduino setup to control the LEDs directly and listen for Twitch messages, so the ideal setup to integrate the PSoC device was to forward the input of the device to Arduino via serial messages. As such, I used the other button to maintain a brightness index, which goes 0-5. Similarly, I do still want to control the brightness, as well as be able to turn the LEDs on and off. This works by maintaining a color index, such that when the button is pressed, it increments the index until it has gone through each color then goes back to 1. As such, I setup one of the buttons to rotate through a selection of colors. The color pallet is fantastic, but it can be tricky to get a specific color, particularly because I'm a big dude and my finger press takes up half the pallet. Instead of just utilizing the base functionality, though, I altered how the buttons work to give myself a little bit more control.

It also comes with an example Color Gamut project, which serves as an excellent starting point for what we're trying to accomplish. The device comes with a very nice color selector and two buttons, which is absolutely perfect for what I'm looking to make here.

I started with getting the PSoC side of things up and running and utilized the PSoC Creator 4.4 software to get things up and running. I'm a big fan of giving myself cool ways to interact with gadgets, and giving fun interaction capabilities on Twitch is just fun, so the rest of the idea built itself out. This expands on something I've wanted to make for awhile, which is the basic sign that indicates that the stream is live in person because it's not only fun, it is a useful way to give loved ones a heads up that there's a stream running to prevent embarrassing moments. Combine that with gaming, 3d printing, and fancy electronics you're supposed to poke and prod and we've got too many boxes checked for me to not get excited about the project.

Unlike a moth, though, I am willing to spend a bunch of time and effort to make a project that is all about big shiny lights. I'm not too proud to admit that, like a moth, I am fond of shiny things.

This is a light up, multicolored sign that activates when the user goes live on Twitch, can be controlled by Twitch chat via commands, and can be controlled in person with capacitive touch by utilizing the PSoC 4 Series Pioneer Kit (I'll be referring to the device I used as the PSoC 4100s for short).
