So I'm working on a guitar pedal project that uses bluetooth. The hm-10, (bluetooth module), is constantly receiving data every 30 milli and then the arduino uses that info to control MCP41100 digipots. The only issue I'm having is that when the bluetooth is turned on you can hear either that data transfer or the stepping of the potentiometer, I'm not sure which. The guitar signal is clean until the bluetooth get connected and the potentiometer starts working. I'm looking for a way to quiet it down if anyone could help.
