hello

i am working with arduino and raspi with comport spiiting out values from pots attached to the arduino board and i keep getting the endless warnings of 

error: unpack type mismatch

error: unpack type mismatch

error: unpack type mismatch​

is there a way to remedy this? i looked around and i heard some people talking about "atof" which i assume is ascii to float.

But i cannot find it anywhere. I thought it was in zexy but maybe i have the wrong name or perhaps i am off the mark entirely

can someone help me out?
