Topic: Find outer diameter using arduino  (Read 307 times) previous topic - next topic


Hello all,

I am working  on infusion pump project on arduino mega. In that i want to measure outer diameter of syringe. I have read somewhere i can find it by using Potentiometers but dont know how?

Can anyone help me to provide mechanism idea of it.

Thanks in advance.


Please post a diagram of the sort of measuring system you have in mind.

How accurate does the measurement need to be?

What about using an electronic vernier caliper - you can get some that can interface to an Arduino.

Two or three hours spent thinking and reading documentation solves most programming problems.
