I have been asked to build a "communication-verifyer" using Arduino.
The unit should be able to record/save/send a communication between units.
I imagine, that the unit should be able to:
1) see if any communication on 433mhz is going on
2) if anything happens on 433mhz record it
with the recorded signal it should be possible to:
1) send it back to the first unit, to verify the quality, and see if the reciecer works propper.
2) send it to another unit, to see if this unit works.
My problem is, that i do not know anything about Arduino and 433mhz communication
Anyone that can help me?
Hi Erik Gotfredsen ,
maybe this is helpful as intro:

Using Arduino Nano boards, for example, is an inexpensive and fast way to get a microcontroller ATmega328P running. However, the Arduino IDE (Integrated Development Environment) is a failed attempt, IMHO. I would use AVR Studio and XLoader (both free), instead.
The transmitter and receiver seem to provide asynchronuous interfaces, so on the microcontroller, you can choose anything from USART, SPI (with clock unused), or an interrupt input (for the receiver).
A prerequisite for success with this project is that you are familiar with the C language, electronics, and CPUs or microcontroller in general. Otherwise, I guess you had to learn too much different things simultaneously.
You can understand it easily from a video tutorial.
