Do you want to adjust the brightness of a RGB LED from your smartfone?
I speak to you today of a communication protocol called OSC (Open Sound Control, in fact it was born as an application in the musical field to allow communication between computers and audio synthesizers, through an ethernet network.
What you need for this project:
- Ethernet shield;
- RGB LED and relative resistance;
- a smartphone (I used my iPhone);
- the TouchOSC App or equivalent application for your smartphone;
- the TouchOSC Editor application to build the interface on the iPhone side;
