Today, we hooked up the spectral sensor to Arduino Uno through i2c connection and recorded the outputted spectral colour values for 3 different types of textiles (cotton, polyester, wool), while controlling the distance of the textile from the sensor, the lighting (natural), and recorded 3 trials for each.
The colour of the material has an effect on the spectral output, therefore we ensured to compare only like colours.
The next steps would be to create the setup in order to begin calibration.
