Dear all,
previously i used interface board to communicate all pins of arduino. Here i am attaching two image actual/ mc . actual represent interface board that takes all pins from arduino boards and get connected to arduino pins. Now, i am replacing interface / arduino board with my board where i am using all schematic involved on UNO board.
I need help to review the schematic MC image. Let me know what are additional parameter , values of passive/active parameter to be changed to work successfully.
Here i have doubt in power isolation. here i have not used isolation between main power and USB. can you let me how can do that. if any circuit please share image of it.
all my sensor requires 12 v inputs and output are 0~5v analog.
i used 5 v regulator for LCD /keypad since when i tried with only arduino board i found power is not efficient to drive LCD.
