After the LEDs and resistors are in, connect 3 MOSFETs to the Pi and each to its own LED + resistor pair.įor those of you who have never worked with MOSFETs before, a MOSFET is a transistor that allows you to reduce the current put out by the Pi. We are using 3 different LEDs because on the LED strip, each color is handled separately (with a 4th wire for power). To get started, line up 3 different colored LEDs and connect each to a resistor. Also, a basic understanding of python would be helpful. I would highly recommend their physical computing-with python tutorial. Also, if you messed up, you would only ruin a 15 cent LED instead of an $18 LED strip.įor those of you who have never worked with a Raspberry Pi before, has a lot of great resources. Though we will be using a LED strip in the final project, it's easier to start with some individual LEDs to test. The Barrel Connector is for powering the LED strip (power cable on the LED strip connects to a barrel connector). The 4 pin connectors (in my case, two of the two pin connectors) connect the breadboard to the LED wires. The T-Cobbler connects to the 40 pin on the Raspberry Pi and connects and labels the 40 pins on the Breadboard. If you aren’t planning on making more projects, all of these individual parts can be bought separately ( see "Bill of Materials" at the end of this article). If you are a DIY enthusiast, you can grab a cheap breadboard kit with most of these materials for under $20. A T-Cobbler would make prototyping easier, but you could get individual wires that would work too. You then need a breadboard and some basic materials like jumper wires, individual LEDs, MOSFETS, and resistors (I would suggest ~100 ohms to prevent your LEDs from combusting spontaneously).

This way you have more USB ports, a full-sized HDMI port, built in Bluetooth and Wifi, and you don’t have to solder pins in the prototype phase. For the prototyping phase, it would be easiest to grab a Raspberry Pi 3 for testing. This way you can get the project to work in an unconstrained environment before worrying about the size and cost of the final project. There are two stages of this project, the prototyping phase and the final solution phase.

How to Build your own Web Controlled LED Strip With the size requirements for the project, in came the Raspberry Pi Zero. The options were endless! We wanted to be able to customize patterns, colors, and change the lights to fit the mood of the room (or the movie!). It would need to be a compact, unobtrusive, and easily controllable. In order to accomplish this, we needed to attach a multicolored LED light strand underneath the stair. It would be so cool if this theater room had such a light that was also interactive! In traditional theaters, there are usually small lights attached under the stairs to give people enough light to walk down the aisle, but not too much to distract from the movie. There is a half stair that leads into the theater room that presented such an opportunity. So when one of our staff was working on a theater room for his house, we were more than ready to lend a hand with a fun IoT project! We have worked on everything from a temperature sensor for the office, to a boost controller for a Subaru WRX. As an IoT (Internet of Things) shop, we love working with new technology and creating fun useful side projects.
