NeoPixels intro

“

- [Instructor] So far, to get up and running the circuit Python we focused on the onboard LED. In this video we're going to explore one of the more visible and fun features of the circuit playground express. The 10 NeoPixels that circle the board. The onboard LED is a simple device connected to a microcontroller pin. You can turn it on and off. NeoPixels on the other hand consists of red, green and blue LEDs with an integrated circuit. You can set the color and brightness of the NeoPixels and multiple NeoPixels can be controlled using a single micro-controller pin. Just like with the onboard LED. There are modules we can use to help program NeoPixels. A generic setup would import the board and NeoPixel modules then set a variable you can use to access the 10 NeoPixels. This setup will work with any circuit Python board that supports NeoPixels but the circuit playground express has a…
