[Lab] ws2812b LEDs

[Janick Bergeron]

The LEDs should be connected in series so the Arduino will only have to drive one input regardless of the length of the strip. Adafruit recommends putting a 1kOhm resistor in series to limit the current.

For the power input, you should use a separate 5V supply, with a common ground with the Arduino. Again, AdaFruit recommends putting a 1mF capacitor across the power supply output to protect the strip.

Check the amperage of the arduino you are using and review what the max amperage for each ws2812b is when they’re full power (aka white) that will tell you how many you will be able to run at once.

I should be okay to run few of those LEDs off
Arduino's 5V out right? (The arduino is plugged into
