Any suggestions to connect trig and echo of ultrasonic to microcontroller via dc

Hi, @Eleckits
What is the solution, to close the thread and make it useful and informative.

Tom.. :smiley: :+1: :coffee: :australia:

What makes you think that the discussion is closed? :face_with_raised_eyebrow:

@ Eleckits,

Please share your solution here, I would be very interested to learn how this can be done.

You might investigate current loop and hart protocol (to send digital data over current loop).

Hi,

Looks good, BUT how did you fix the problem?
This forum is to help people and to post the solutions to help other people.

Thanks.. Tom... :smiley: :+1: :coffee: :australia:

thanks guys for asking, by the way some company ask me to do production of the solution so if they do not do contract with me I will post all details here later :slight_smile:

Hi,
Arduino is Open Source, so how about some Open Source in return.

That would be very generous of you. When do you expect them to make a desicion ?
If they do contract you, maybe you can provide a link to this company so we can see the final product ?
