# PiicoDev VEML6040 minimal example code

# This program reads light data from the PiicoDev VEML6040 Colour Sensor

# Displays Raw Data, and classifies colours as fruits

from PiicoDev_VEML6040 import PiicoDev_VEML6040

from PiicoDev_Unified import sleep_ms # cross-platform compatible sleep function

# Associate a hue value with a fruit name

fruitList = {

"apple":0,

"carrot":60,

"lime":120

}

colourSensor = PiicoDev_VEML6040() # initialise the sensor

while True:

### Example 1: Print Raw RGB Data

data = colourSensor.readRGB() # Read the sensor (Colour space: Red Green Blue)

red = data['red'] # extract the RGB information from data

grn = data['green']

blu = data['blue']

print(str(blu) + " Blue " + str(grn) + " Green " + str(red) + " Red") # Print the data. Printing as BGR so the Thonny plot-colours match nicely :)

### Example 2: Classify the colour being shown - eg. a fruit sorting machine

# data = colourSensor.readHSV() # Read the sensor (Colour space: Hue Saturation Value)

# hue = data['hue'] # extract the Hue information from data

#

# label = colourSensor.classifyHue() # Read the sensor again, this time classify the colour

# print(str(label) + " Hue: " + str(hue)) # Show the label and the corresponding hue
