(Video) To design a NeoPixel to analog LED signal converter, we need to convert 3 open-drain PWM outputs to drive current-carrying N-channel MOSFETs. To do this, we need to invert the signal – but we don’t have enough space. So let’s find a triple NOT gate that has a push-pull output and can operate at 3 or 5 V logic voltage. We also want it to be small, but not too small!

Stop prototyping and soldering – start building right now! The Adafruit playground is filled with LEDs, sensors, buttons, alligator clips and more. Build projects in minutes with Circuit Playground through MakeCode’s drag-and-drop programming site, learn computer science with CS Discoveries courses on code.org, jump into CircuitPython and learn Python with hardware, TinyGO, and even use the Arduino IDE. Circuit Playground Express is the latest and greatest Circuit Playground board that supports CircuitPython, MakeCode and Arduino. It has a powerful processor, 10 NeoPixels, a mini speaker, infrared transmit and receive, two buttons, a switch, 14 alligator clip pads and a large number of sensors: capacitive touch, infrared proximity, temperature, light, motion and sound. A vast world of electronics and programming awaits you, right in the palm of your hand.
