- I am using multiple DC-DC converters to obtain 12V and 5V. Shall I use non-isolated or isolated converter for Arduino's? From what I have read so far, isolated are used when you have inductive loads and you need isolation in between your motor and the signals which are used to control the motor.
- Also, Shall I use an opto isolator in between the Arduino and the DC motor,as my Arduino is going to control the DC motor like this:
- Also do the use of isloated DC-DC converter eliminate the need of opto-isolators , precisely because the ground terminal is separated?
PS: I know my questions previously were vague and I understand the requirements of this forum. I have tried to take care of it this time and I will appreciate if someone can help me with the confusion here. Thanks
