Tutorial – Fading a RGB LED on BeagleBone Black. In this tutorial, you will learn how to control the color of an RGB LED using a BeagleBone Black (BBB). Because the BBB runs Linux, there are many ways in which it can be programmed. In this tutorial we show how to control the power output of a GPIO pin and hence control the color of an RGB LED using Python. The tutorial uses a technique called PWM (Pulse WIdth Modulation) to vary the brightness of each color channel between 0 and 100.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
