Arduino bluetooth hc-06 car

You can go on with guessings for days, weeks, months. Please do yourself and us a favor to
speeding up solving your problem.
I have encountered so many misunderstandings that I insist on everyone to post all relevant basic information that is nescessary to proceed fast

If you want to proceed slow post only short postings always waiting for an answer where the "answer" is just aksing back for another detail you left out trying to be fast. You should post information about:

  • exact type of microcontroller you are using
  • typenumbers and links todatasheets of all parts that are connected
  • no Fritzing picture !!
  • instead a handrawn schematic how things are wired together

best thing is to take 15 minutes of your time to read this guide

do yourself a favor and really read it!

best regards Stefan
