Designed around 4 White LEDs and the TAOS TCS230 sensor IC. The four white LED’s to provide a broad spectrum light source .The TCS230 has an 8 x 8 array of photodiodes with color filters (16 Red, 16 Blue, 16 Green, 16 Clear). A light to frequency converter generates a 50% duty cycle square wave on the output pin. Frequency is directly proportional to light intensity. Output scaling 100%, 20% and 2% allows for wide dynamic range of intensities. The color selects (S2, S3), frequency scale (S0, S1) and output are TTL logic level and can be connected directly to the micro controller. Basic readings are easy using the Arduino “pulsein” command. Take a reading for each color. The reading with narrowest pulse width or highest frequency is the major color. Using advanced ratio analysis almost any color could be recognized. Multiple uses by adding lenses, color filters, different light source.
