Hi,
I am new to the forum and have done some research but cannot seem to find the correct answers.
I honestly am just trying to get into building my own bluetooth speakers so my knowledge is very limited, hence my questions on here.
I have the done the following but I am not getting the system to work:
I am trying to get a potentiometer to turn the Bluetooth module and amp on as well as control the volume.
I have 3 wires coming out of the Bluetooth module
Positive audio
Negative audio
Ground
The are connected to the potentiometer's top row of pins in the order from left to right.
Ground
Negative
Positive
The 2nd row of pins on the potentiometer are connected to the amp as follows, also left to right.
First pin blank ?
Amp in negative
Amp in positive
Power to the USB Bluetooth module is 5v supply so I presume the potentiometer will not control the power to that.
After the amp the speakers are connected as well as power in from the same 5v supply. I then have vcc and ground from the amp connected to a step down converter as well as power and then into a dc /dc isolating converter which feeds the usb bluetooth module.
Can anyone guide me on what is wrong with this? I got the component specifications and design from the diy perks YouTube channel.
Please see attached drawing
Thanks in advance
