Basic usage

//Initializes the gator:particle so we can use it
gatorParticle.begin()

Use ||Initialize gator:particle sensor|| to start the gator:particle up so we can read from it.

//Reads a value from the Red or Infrared LED
gatorParticle.color(LEDToRead.Red)

Use ||Red value|| to get the value from the red channel. Grabbing the infrared channel is as easy as using the dropdown to call ||Infrared value||

//Reads the heartbeat of a finger pressed to the sensor in BPM or as a running average of 4 BPM readings.
gatorParticle.heartbeat(heartbeatType.BPM)

Use ||heartbeat in BPM|| to get the heartbeat of finger on the sensor in BPM. Grabbing the average BPM is as easy as using the dropdown to call ||heartbeat in AVG||

Example: Red Detector

//Read red value and write it to the micro:bit screen as a bar graph.
gatorParticle.begin()
basic.forever(function () {
    led.plotBarGraph(
    gatorParticle.color(LEDToRead.red),
    65000
    )
})
