Hello,
i think i got a problem with my Arduino Nano or Mega 2560.
The problem is i've tested 10 nrf24l01 and a pear of 433 Mhz modules.
None of these moduls had send any data or received data.
Is there a way to test if there is a problem with my arduino ?
you can do some basic tests and see if the digitalWrite and digitalRead works with a few leds and a breadboard wire
also analogRead can be tested fairly easily.
For Serial, I2C and SPI you need a second device known to work.
A DMM (digital Multimeter) can also help here

It could be faulty code of course. Have you got some known-good sample code?

I already got an LCD and soil moisture Modul working

With the 433Mhz Module i've used Virtual Wire and the standart examples.
With the NRF24l01 modules i've used the examples of Mirf and two other NRF24 librarys.
For the 433Mhz i've tested this tutorial to:
Try the APC220 430 MHz RF module. It's easy to check: serial data in/out. Just connect it to your serial output port to transmit data.
Receiver module can be connected to a PC USB port, and you can see the transmitted data in a terminal emulator.
