Hi,
I'm hoping someone can help me connect a logarithmic potentiometer to a circuit. I just need it to adjust the volume of the spoken output. The current will be very small, so I'm thinking of getting a 0.5W potentiometer. Once I order it though, how do I connect it to the circuit?
If anyone can help, I'd be really grateful.
Thanks
One end of the resistor element connects to the signal source, one end to ground or signal common.
Set the sliding contact to the middle position and measure the resistance to each end. The end with the higher resistance reading is the one that goes to the signal source.
The sliding contact is the variable volume output signal.
Selecting the best pot resistance value depends on the rest of the circuit.
