i'm starting to play with a arduino pro mini (clone from china) i bought some time ago.
Since it has digital pins, pwm control. analogue in and so on, i thought i would have found tons of sketches to turn this into a "sensor" for raspberry on i2c (something like a mcp23017 + a 8 ways adc and so on)
But my googling miserably failed so i'm wondering if i lost something (About feasibility of this task)
something like that a sketch managing i2c slave and all of this would never fit in arduino's memory.
On the other hand, this could be a stupid idea for a reason i'm missing
