Hi there
I have reviewed your requirement and i would like to ask you few questions over it as you need to use arduinio uno or arduino nano and what are the other hardware you need to use as i have done many work with arduino, as i am doing work with controllers from last 8 years from my graduation time.
I have done work with many controllers like as 8051, pic, avr , arm, arduino, rasberry pie etc... I need to discuss few points in detail on your requirement.
I can show you my previous work and my coding style in personal chat so please initiate chat for further discussion in detail over chat, please open chat box
Regards
Abhi
