maybe someone could help me
I have a 32V high power led which I want to power by a 12V battery. If I am correct, i could use a boost converter, but my problem is that I want to control the brightness with an arduino. So I need to control the boost converter in order to control the voltage and also I could measure the current and adjust the voltage if the led consumes to much current and runs hot. But I can't find any boost converter that is controllable via Arduino. Most boost converter are only adjustable with a potentiometer...
Does anyone has a idea how to solve this problem?
