This sample demonstrates reading RGB light.

To run the sample:

  1. 2.
    Copy the sample code to a folder on the Raspberry Pi.
  2. 3.
    Open terminal, and then go to the folder you copied the sample.
  3. 4.
    Run the sample with the following command:
python3 RGB_Light.py

Sample Code

RGB_Light.py
o#!/usr/bin/env python3
#This sample demonstrates reading RGB light.
#Install IoT HAT 3 library with "pip3 install turta-iothat3"
from time import sleep
from turta_iothat3 import Turta_Light
#Initialize
light = Turta_Light.LightSensor()
try:
while True:
#Read clear & RGB light values
crgb = light.read_crgb_light()
#Print the readings
print("Clear...........: " + str(crgb[0]))
print("Red.............: " + str(crgb[1]))
print("Green...........: " + str(crgb[2]))
print("Blue............: " + str(crgb[3]))
#Wait
print("-----")
sleep(0.5)
#Exit on CTRL+C
except KeyboardInterrupt:
print('Bye.')

Result

When you run the sample, it prints clear and RGB light measurements. The example output should be like this:
Clear...........: 0
Red.............: 0
Green...........: 0
Blue............: 0
