MakeCode Package for the SEN-Color (TCS3200 Color Sensor).

This library provides a Microsoft Makecode package for the Joy-IT SEN-Color TCS3200 color sensor. See https://joy-it.net/products/SEN-Color for more details.

Connection

By default the color sensors is connected as follows:

SEN-Color	Micro:bit
VCC	3V
GND	GND
OE	NC (Not connected)
LED	GND (on the color sensor)
GND	LED (on the color sensor)
S0	P15
S1	P1
S2	P8
S3	P12
OUT	P2

But the pin assignment of S0, S1, S2, S3 and OUT can be changed to any digital pins by using:

// Set pin assignment
SENColor.setPins(DigitalPin.P15, DigitalPin.P1, DigitalPin.P8, DigitalPin.P12, DigitalPin.P2)

Calibration

The sensor needs to be calibrated before each use. This is done by using the calibration function and holding the sensor in front of a white surface (e.g. a white sheet of paper). In the following example the calibration function is mapped to the “A”-button of the Micro:bit. This way the calibration function is always accessible.

Run
// Calibrate sensor when pressing the A button on the Micro:bit
input.onButtonPressed(Button.A, function () {
    SENColor.calibrate()
})

Measuring colors

The color component of each color can be measured. The function expects the component that you want to measure (red, green or blue) and returns the value as a numeric value.

Run
// Retreive all 3 color components and print them to the console
serial.writeLine("R: " + SENColor.getColor(color.red))
serial.writeLine("G: " + SENColor.getColor(color.green))
serial.writeLine("B: " + SENColor.getColor(color.blue))
