Thank you

DIY Arduino
For a robot I have designed a custom arduino sketch to make a custom low profile PCB. Can you review it and tell me if there is something wrong. I want good analog input accuracy as I have some analog inputs. Please tell me if there is anything I have to improve or add or edit. arduinoDIY.png Thank ...
