Sorry for sounding like a complete newbie (but I am). I’ve just discovered arduino through google. Can I use it as a constant current source?
Basically what I want it to do: supply an (dc) output of x miliamps. It would be directed/connected to a sheet of a semiconductor.
And the other side of the sheet would be measured and recorded(also by arduino)for the voltage drop.
Now the second part (V) is not so critical, I can just use and external multimeter, but can I use arduino the way I want for the current source. If so, I’ve read it can only output as much as 20-40 miliAmps. If I wanted to go higher, say 500 miliamp and higher, can Arduino do that? If not, are there any similar alternatives?
