![]() ![]() Controlling an individual pixel is very easy. ![]() ![]() Np on the GPIO you’ve defined earlier and with the number of LEDs you’ve also defined: np = neopixel.NeoPixel(machine.Pin(p), n) Controlling individual pixelsĪfter initializing the neopixel object, you can start controlling the LEDs. Save the GPIO number that will control the strip on the p variable: p = 5 Set the number of pixels in your strip to the n variable: n = 48 Neopixel and machine modules: import machine, neopixel Create a neopixel object Np = neopixel.NeoPixel(machine.Pin(p), n) For example, the next script controls 4 individual pixels: # Complete project details at There’s a built-in MicroPython module called neopixel to control WS2812B addressable LEDs. You need to apply 5V to the VCC pin, GND to GND and connect a GPIO to the Din (data) pin. To wire the RGB LED strip to the ESP32 or ESP8266 is very simple. The following figure shows how our setup looks like after soldering the LEDs. Each PCB has IN and OUT pins that make wiring very simple: You can solder several LED rings and sticks and they will behave as one piece. ![]()
