Nrf24l01 arduino doesnt work

But you failed to post the new sketches (and new connections?). :wink:

You did run the connection test sketch from Robin2's tutorial to make sure you can communicate?

If not, it's time to. (You will have to adapt it to match your hardware connections).

A small capacitor (1 to 10 uF) directly on the module power pins
sometimes helps the modules work in case of a marginal power supply.
