Hello there,
I'm about to develop my first circuit for a project at my university and I think I could need some help. Thanks in advance!
I've got 4 sensors, a microcontroller is to read the outputs. I designed circuits to adjust the voltages to the A/D input of the controller. I protoyped the circuit without the microcontroller and it works just fine.
1) Are there any more capacitors needed to keep interference out? I can't seem to find any information on a) where they're needed in DC circuits, b) how big they should be, c) what type they should be?
2) The PIC and the circuit will not be on the same board, hence the provisory connector. Am I right that the load resistances should be as near to the pic as possible? I figured that it's better to have bigger currents over the wires than small ones.
Is there anything else to improve?
Thanks in advance!
