This week, in preparation for ASEE, I created an Instructable on controlling an LED Strip with LabVIEW. For this project, I used LabVIEW, the chipKIT WF32, the WS2812 LED Strip, and LabVIEW MakerHub LINX.
After installing the software, the setup is very simple. A 5V external power supply is used so the WF32 can supply 5V to the LED strip. The “digital in” port on the LED strip was connected to a digital channel on the WF32. This digital channel controlled which LEDs were lit up and how they lit up. The code under the hood created different waves with different amplitudes, frequencies, and offsets for red, green, and blue. These waves were then packaged together to create a color that is then sent to the LED strip.
Here is the Instructable for this project. Feel free to post a comment if you have any questions!
