If you're experiencing issues with the NRF24L01 module only transmitting when the ground pin is disconnected from the Arduino Uno, there might be a few things to check and troubleshoot:
Wiring: Ensure that all your connections between the Arduino Uno and the NRF24L01 module are correct. Double-check the wiring against the pinout diagrams for both the Arduino Uno and the NRF24L01 module. Make sure there are no loose connections or short circuits.
lobotomy dashPower Supply: Make sure that both the Arduino Uno and the NRF24L01 module are being adequately powered. The NRF24L01 module may require more power when transmitting, so ensure that your power supply can provide enough current. It's recommended to use a separate power supply for the NRF24L01 module if possible.
