This project is based on the Grove - I2C Color Sensor, with enhancement using the Grove - Variable Color LED instead of the former white Led. In more there are improvements at the Arduino sketch and a nice Processing sketch for visualizing the results.
STEPS TO FOLLOW:
- * Hacking the Variable Color LED<
- You'll have to remove the LED, and add copper wires in order to align the top of the led with the top of the colour sensor:
- * mechanical assembly
- Join the two PCB together and use glue to maintain the LED in place.
- I used a glass of 4mm thickness on the top of this sensor.
- * wiring it all together
- * Loading the Arduino sketch
- * Install and launch the Processing sketch
- * Calibration
- Place a white paper sheet on top of the glass of your sensor.<
- Then adjust the RVB LED's potentiometers in order to obtain values near 300 for Red, Green, and Blue, and 550 for the Clr (see picture below):
- * Play with it
