Concept
Photodiodes with RGB filters; output is a square wave whose frequency tracks light.
A little theory
pulseIn() on OUT. S2/S3 select filter. Calibrate on black/white. In the classroom, treat TCS3200 / TCS230 Colour Sensor as a intermediate part using Frequency out + S0–S3 select. Typical India street price is about ₹120–₹250. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
Cover ambient light; map R/G/B frequencies to a colour name.
