I´m trying to characterize my dye sensitized solar cell with Arduino.
I have found this article: Homepage | Accelerated Materials Laboratory for Sustainability. They use the Arduino Mega, my question is: Can I use the Arduino UNO instead of the Mega?
Another point, how can I adapt the circuit to be able to measure micro-Amper?
I compiled their Arduino code for a Nano (essentially same as UNO) and got this result:
Sketch uses 6,020 bytes (19%) of program storage space. Maximum is 30,720 bytes.
Global variables use 389 bytes (18%) of dynamic memory, leaving 1,659 bytes for local variables. Maximum is 2,048 bytes.
So the code will fit in the Nano. Unless it needs more pins than a Nano, it should work.
