The ESP32's analog input pin converts the voltage (between 0v and 3.3V) into integer values (between 0 and 4095), called ADC value or analog value. $0.24-$0.26 / piece. If you use too high a value for the potentiometer the amplifier input impedance will load it excessively and distort the volume curve. The one used in this mini-project is labelled "B50K", meaning 50KOhm linear. This tutorial will show you how to set up an arduinoUNO to produce a tone through standard earphones, with volume control via potentiometer, with visual volume display via LCD, with pause/play button. Amplifier sees ~= 11.5 ohms Power amp = 6/11.5 x 30 =~ 15 Watt. The volume is too loud, as they tend to be, so I am installing a Potentiometer to use to control the volume going to the two speakers. The load impedance of a passive volume control has to be much higher than the driver and max the impedance of the load impedance of the input.
