Description
The module is designed to measure the intensity of RGB light, separately for red, green and blue. For example, when the measurement is performed for the blue colors, a suitable filter blocks red and green. It is powered with the voltage of 3.3 V, and communicates through an I2C interface. Read measurement data may be, for example, for pattern matching or to help a mobile robot in the decision making.
The sensor operates with a voltage of 3.3 V, to connect it to the module operating at 5 Volts, it is necessary to applya voltage converter,for example, a module from the SparkFunorMSX.

The product is compatible with Arduino The manufacturer offers auser manualandlibraryfor users ofArduino. |
Connection
The module has five holes for goldpin connectors- 2.54 mm pitch (not included in package, sold separately). All pins are appropriately signed on the board. For facilitating the connectivity, the manufacturer has installed the resistors pulling up the line of the I2C bus (10 kΩ). Items can be disconnected by cutting the connection between the pads of the jumper SDA 3.3 V SCL.
| Pin | Description |
