Hello!
I guess everything has been said about the functionality, and the care you have to take about
possibly high voltages, currents, etc...
Now from my point of view, assuming everything you have drawn is right, you should consider
not to write your circuit in a single block. It makes small circuits look unnecessarily complicated.
Some hints:
- Don'r draw the ground line, there are symbols for ground, that you can place everywhere you want.
The cad software (I would recommend Kicad with is free and powerful), will know that all the grounds
symbols are a single symbol and are connected.
- Same remark for your power line (+5V).
- Divide your circuits into blocks. And you should start drawing this way as soon as possible otherwise
you will just keep producing work that nobody else can use. Can you imagine the schematic of your PC
written this way?
Example of good practice:
- Write the analog preconditioning part, that will transform the input into an ADC input signal.
Or 2 because apparently you have 2 ADCs used.
- Write the CPU block, with labels ADC0 and ADC1 that are not connected to the analog part,
but simply labeled. And if your cad sofware has ADC0 at two places (even 2 different sheets), it
will know that they are connected. Exactly as it does it for ground and +5V as explained above.
