Connecting the Sensor to the JackBord


The sensor uses the I2C bus on the JackBord, which is located on port D. The diagram below shows the connections between the color sensor and the JackBord.



Once you have connected the sensor to the JackBord log into your dashboard and open the command line. Once there we need to type the following commands

1. To turn on the I2C System, type:

i2con

2. To find the color sensor, type:

f2c

This will find the sensor and display a result like the one below.

> f2c
< Finding I2C Devices....
< TCS34725 RGB Color Sensor at address [41]
< Found 1 devices

If the sensor is not found check your connections.

3. To get some readings, type:

gt
