Serial Monitor Output - Giving odd combination of number values and question marks/blank squares...

Hey there,

After I got my program working and actually spitting out some sort of values, tied into the values are a combination of question marks, empty squares, apostrophes, and a few random letters. Here’s a snippet of what it is giving me:

0: 895 1: 901

0: 895 1: 901

0: 895 1: 901

0: 895 1: 901⸮

0: 895 1: 901⸮

0: 895 1:ʂ⸮⸮

⸮0: 895 1: 901

0: 89M⸮1: 901

0: 8NM⸮1: 901

0: 895⸮1: 901

0: 895 1: 901

0: 895 1: 901

0: 895 1: 901

0: 895 1: 901

0’⸮ʪ1: 90L⸮

0: 895 1’ʂ⸮

0: 895 1: 901

0:⸮ʪ⸮1: 901

The data should be 0: 895 1: 901 /n

and continue on until I change the value on the potentiometer. The values DO in fact change when I want them to, but there is just this mess of stuff sprinkled in between… Not too sure what’s going on here?

Thanks for your help,

Cody

Hi Cody.

What baud rate are you running? You might try slowing that down a bit and see if the issue clears up.
