iPad control of my high power led drivers

This is an incremental project. Meaning I will have very small proof-of-concept projects that will prove the steps to a complete project. This first mini-project is a simple, no need for an elegant UI, driver for my high power LED driver. The led driver’s brightness can be controlled by a 0-10volt signal or a 100K digital potentiometer. To complete the project you will have to identify the hardware that you are going to control. Either a 0-10volt device or a 100K digital potentiometer. And then control it from a “slider” displayed on the iPad screen.
