Read the introduction. Connect your Arduino and test tube color sensor.
Microcontroller plugged in and test tube color sensor attached.
The test tube color sensor has a white LED on one side and a color sensor on the other. You can use the measurements from the color sensor to test for a color change as part of a chemical reaction.
In the next section we'll be using the test tube color sensor. Attach the LED to digital pin 2 and the color sensor to an I2C pin on your grove shield.
Read the text. Click the red, green, or blue blocks to see a plot of their values.
In this section you can see the readings for the red, green, and blue channels of the color sensor. The maximum value for each channel is 65535.
