regulated power for potentiometer
Apologies if this question has already been discussed in detail in another thread. A quick search returned no helpful results. What is(are) the recommended way(s) to power a potentiometer so that the signal is less affected by battery voltage change? Would it be helpful (and legal) to tap into the power going to the radio? Or perhaps do A/D on both the signal and the power to the pot, and use the ratio? |
