Help, i'm new to this

Hello World!!

Now I'm completely new to programming electronics but advanced level on hardware.

I've got two units. Arduino Pro, and Pro Mini.

What I'm trying to do is use the "mini" as a TX and the Pro as an RX.

I have 433 MHz transmitter and receiver modules so send from one unit to the other.

At this stage I just want to send 2 digital signals from one to the other, but in the future also analog.

So in a nutshell. push button 1 or 2 on mini unit, sends on 434 MHz to Pro unit, output 1 or 2 will switch relay 1 or two.

Now all I've learned in programming is localised to 1 unit (defining pins, output high/low etc. ) but that, so far, is the extent of it.

Thanks in advance! :slight_smile:

The radios send data, not digital signals.

Thanks for the quick replies.

I've looked through a couple of examples but am having trouble understanding how you send and received this data.

is it possible to get some help with the coding?

so once I've type the pins to be inputs and set the baud rate, do I allocate that signal to a 'bit' which then on the receiving side refer that bit to a output pin?

(remember no coding knowledge here :wink: )

Thank you LarryD, That PDF is Perfect :slight_smile:

The examples in Serial Input Basics may be useful - especially the 3rd example.

If you design the system for receiving data it should be easy to make the "sender" comply with that system.
