There are libraries for MicroPython that make it easy to control WS2812 LEDs. The `neopixel` library is designed specifically for this purpose and will allow you to dynamically control the color and brightness of the LEDs. You can implement a function to change the brightness of the LED over time, creating that heartbeat effect. Using a loop and the `time.sleep()` function, you can gradually increase and decrease the brightness, simulating a pulsing effect.
