Note: This sensor will EOL soon, please consider the new version Grove - I2C color sensor V2.
The video shows how to recognize different colors with the sensor and then to drive the lamp lighting in blue, green, yellow, orange and red accordingly.
This module is based on the color sensor TCS3414CS with digital output I2C. Based on the 8*2 array of filtered photodiodes and 16-bits analog-to-digital converters, you can gain the color chromaticity of ambient light or the color of objects. Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have blue filters and 4 have no filter(clear). With the synchronization input pin, external pulsed light source can provides precise synchronous conversion control.
Grove compatible interface
16-Bit digital output with I 2C at 400 kHz
SYNC Input Synchronizes Integration Cycle to Modulated Light Sources
Operating temperature range -40°C to 85°C
Programmable interrupt function with User-Defined Upper and lower threshold settings

Can you tell me what is maximum detection distance? Is it just 2-3 cm, or more, like 15-20cm ?
What does the INT pin on the right of the Grove connector does?
How can i connect more then one color sensor on a base shield? I tried with different addreses but it doesnt seem to work?
Is it posible to power the vcc with 5v but have the i2c run over 3v?
What is the black ring for? Is it simply there for light shielding and spacing or is it meant for screwing in lenses or cuvets?
The wiki suggests that the built-in white LED can be deactivated for use with an external light source. However, I cannot determine how this can be done. Can you explain how to do this?
We are thinking in using the I2C color sensor to detect different line colors painted in a floor, as the robot moves around. The sensor must be at 2 or 3 centimeters from the floor. Can you tell us if the sensor is suitable for this applic
