Read 433MHz raw sent from a PIC12

I am trying to make a simple Hello world kind of application using a cheap non-branded transmitter and receiver. No encryption, I just would like to see the "Hello world" received.

The sender is a PIC12F1822 set to 1200 kbps. I tested that and I can see that it is transmitting in Putty.

I would like to read those characters on an Arduino UNO but not quite sure how to get started. There is nothing else for the Arduino to do just read the RF module and blink a led when "Hello world" is received.

I see that there are some nice libraries (not yet sure if any would fit). Or, if possible, it would be rather great to pull the data from the RF receiver if Arduino has a way to do it.

It would be great to see some example code or link to a project doing this, if anyone knows how to do it.

Thank you :slight_smile:

That is a horendously fast data speed! Are you sure of your numbers?

Alright, 1200 bps then :slight_smile:

Any idea for the question, other than that?

That is very confusing! Are you using a receiver to receive the RF transmitted data and showing that on a PC, or are you just looking at the serial output of the transmitter and showing that on your PC?

If that is from a serial output of a device you think is also transmitting how confident are you that what you are seeing is one-for-one what is being sent by RF?

Actually time for a block diagram showing what you have and how you have connected it to give the output you see on your PC/

Question:
How to write Arduino code when

PIC12 -- RF Transmitter ~~~~ [air] ~~~~ RF Transceiver -- Arduino
Sends "Hello world"                     Receives "Hello world"

Any code that can read serial data can replace your "Putty" on your project if "COM1" is on the USB of your PC. You already know the proper Baud rate.
