A shareable EDWartens certificate

Finish every module and pass the final assessment, and you can buy a certificate for ₹700. It carries a unique verification code on a public page anyone can check, so it stands up when a recruiter looks it up.

  • Add it to your LinkedIn profile in one click
  • Link it from a CV or portfolio, the URL is permanent
  • Publicly verifiable by code, not a PDF anyone can edit
  • Issued by EDWartens India, the training centre itself

The course itself stays free whether or not you ever buy one.

Stuck? Ask a practising engineer

A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.

  • Questions answered in the context of the module you are on
  • The same engineers who teach the AEP programme
  • Career tools, CV help and public job listings included
  • Your progress and notes stay in your account for good

Common questions

Is Node-RED a PLC replacement?

No. It moves data, builds dashboards and integrates systems; the PLC keeps control. The course is explicit about that boundary.

Do I need hardware?

No. Node-RED on your PC with simulated devices covers every module; a Raspberry Pi and a USB-RS485 adapter make the Modbus modules real.

Do I need to code?

A little JavaScript in function nodes, taught as you go.

Is the course really free?

Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.

What certificate do I get, and is it a vendor qualification?

An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not a vendor credential and is never described as one.
