Hello Arduino Fans,
I would like to build a cathodic protection (prevents steel from rusting) model using either the Arduino Uno or Mega 2650. Does anyone have a sketch or instructions?
We could make a team and start this project. i also have some sketch
Welcome. Post what you have and give a better description. Read the forum guide (at the top of every section). Use code tags when you post code. Read other posts to increment your status and privileges
Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project 
See About the Installation & Troubleshooting category.
FYI, your topic title refers to a Due but your text refers to Uno/Mega.
Don’t you just impress a voltage and that’s it ?
no it is fully project
Please explain the project in full and how cathodic protection fits into the project. At the moment I cannot imagine how this would work.
What would DUE contribute to principle of cathodic protection?
we would like to make impressed current to protect any structure(tanks, pipes and extra).
the controller will test to facilitate all requirements of system like on potential and off potential measurements and also to control the modes of operation like constants current ,constant potential and constant voltage and extra.
we would like to do full system.
Ok, that's a reasonable top level description of your project.
In your first post you asked for a sketch or instructions. If such a thing exists then ask your favourite search engine to find it for you. If not then no one is likely to give it to you. You can either develop it yourself, when you get stuck ask for help with your specific problem. If you don't want to do it yourself then there might be someone who will do it for a fee. If you want that then please ask me or one of the other moderators to move this topic to the paid work section of the forum.
Thank you
I think you need to lookup up constant current constant voltage sources and measurement of different metal junction potentials , then go from there .
