Step-by-Step Instructions

In this section, I provide step-by-step instructions to use the sensor.
On the Arduino side, I'm using:

The Avago ADJD-S371-Q999 is a 4-channel, red, green, bleu and clear, 10-bit colour sensor with built-in white LED.
On the fischertechnik side, I'm using
  • a Robo TX controller (here or there)
  • one switch
  • three lamps

The Robo TX controller is I²C capable but, as at today, this feature is under development. So connecting the Avago sensor directly can't work!
I use the following colours:
  •  red  cable for 5V
  •  black  cable for ground
  •  blue  cable for I2C SCL
  •  green  cable for I2C SDA
  •  white  cable for D0
  •  yellow  cable for D1

Step-by-Step Arduino Cabling

I provide the step-by-step cabling:
  • empty board
  • power and I2C connections between Arduino and logic level connector
 
  • power connections between colour sensor and logic level convertor and 5V for the built-in LED
  • I2C connections between colour sensor and logic level convertor 
  • digital connections between Arduino and opto-isolator
  • cables from opto-isolator to the fischertechnik TX controller

Connecting Arduino to fischertechnik TX Controller 

The outputs from Arduino use the same colours as previously and are connected to the inputs of the fischertechnik TX controller:
  •  red  cable from opto-isolator power to fischertechnik +9V
  •  black  cable from opto-isolator ground to fischertechnik ground
  •  white  cable for from opto-isolator EXT1 to fischertechnik i1 input
  •  yellow  cable for from opto-isolator EXT2 to fischertechnik i2 input  

fischertechnik Cabling

The fischertechnik controller is connected to the following standard devices:
  • an emergency switch on i8, 
  • a blue lamp on m1, 
  • a red lamp on m2 and 
  • a white lamp on m3.

The Final Touch

Some fischertechnik blocks on the board!
Unfortunately, the cable spaghettis are still there!
