Even though there is lots of example code for NeoPixels for AVR, Propeller and PIC chips, it’s a bit of challenge getting these LEDs to work with the Netduino. With the default firmware of the Netduino (any variation, Plus or no), it is not possible to send data to NeoPixels.
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.
