Here is another project with High Power RGB LED Shield and Arduino.
This is rather simple way of communicated with the computer and can be useful for initial testing and color matching.
What you need
- Arduino (any version)
- High Power RGB LED shield
- RGB LED
- HPRGB Library : powering High Power RGB LED Shield
Rapplogic made nice color picker application with Processing. You don’t need to modify any code in here. If you have trouble running the application, make sure to put path and changing com port in ledcolorpicker.cmd (windows) or ledcolorpicker.sh (mac osx and linux)
Circuit & Setup
No special circuit here. Just setup Arduino + HP RGB Shield + LED, then connect to a computer.
The couple of lines of arduino code has been modified to make it work with HP RGB Shield.
It is essentially just changing “analogWrite” to “goToRGB”. For version 1 shield users, change shield library include to “#include <HPRGB.h>”.
Demonstration of setup and code
- Will be added soon.
