Lately I have been playing around with a neopixel ring. I have been trying to make a clock for my bedroom using Neopixels and a ESP8266 microcontroller.
The ESP8266 comes with a wi fi module so I can use my dad’s temperature sensors to display the outside temperature.
A neopixel is a set of three LEDs with its own “driver” built in, as such they need a microcontroller such as an esp8266, arduino or other.
There is a 330 ohm resistor between the esp8266 and the input data pin and a 1000μF 16v capacitor between the power pins.
Will post updates as I seem to have broken the code!
