So I have the voltage regulator connected to the NRF module and the voltage regulator is connected to the 5 V output pin (VCC) on the pro mini. I have wired everything the exact same, pin-wise, and have a 9V battery connected to the pro mini V_in and then a 5 V power supply powering the potentiometer (also note I have a button powered by the same 5 V power supply). Everything shares a common ground through my breadboard. Could it be the voltage in to the Pot and button is not sufficient maybe?
