Needing help with programming

If you want someone to write a program for you please ask in the Gigs and Collaborations section of the Forum and be prepared to pay.

If you want to learn to program yourself the examples that come with the Arduino IDE are a good place to start. There are also many online tutorials. Also see the Useful Links Thread.

Whether you want help here or in Gigs and Collaborations you can't just refer to the things at the ends of your diagram as "devices". You need to tell us exactly what they are and provide links to their datasheets with full specifications.

A good description of the overall purpose of the project will also be essential.


Hi, Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.,148850.0.html .

OPs diagram. |500x375 Can you post the data/specs on the "devices" please?

Thanks.. Tom.. :)


  • How far apart are the UNOs?
  • What is the data rate of the devices?
  • How do you expect to have the two UNOs communicate?
  • Can you post links to data/specs for the devices?

Thanks… Tom… :slight_smile:

125kHz is low frequency. Is this an ID tag reader or a vehicle ground loop type of device ?

Hi, Why do you need the two UNOs? What does the system communicate with?

We need you to tell the full story of your application, so we can give you some precise answers.

Thanks.. Tom.. :)

It seems the OP has decided to take his ball home.

How rude.
