NodeMCU Based Color Finder using TCS3200 Sensor

Updated: Nov 27, 2021

In this tutorial we will make a color Finder using a color sensor TCS3200, LCD display and NodeMCU8266 12E dev board. TCS3200 consisting of 64 diode in the combination which are embedded in a single small chip. the working depends on the main fact which is, every 16 diodes are coated with a different color. RED, BLUE, Green, and transparent. when the light refracts from these color patterns every four different colors coated photodiodes will receive the different light frequency. which helps the sensor to differentiate between the color.
