Potentiometers can be used as voltage dividers. To use the potentiometer as a voltage divider, all the three pins are connected. One of the outer pins is connected to the GND, the other to Vcc and the middle pin is the voltage output. When the potentiometer is used as a voltage divider...
To control the brightness of the backlight we can use the third pin (contrast) of 16×2 LCD by rotating the potentiometer knob in a clockwise or anticlockwise direction. The first pin of LCD is ground and the second pin is the VCC (5V). Now, the connection of potentiometer with LCD is...

electronic control to vary its resistance, based on the variation of this resistance the voltage across it and current through it is controlled with respect to Ohms Law. The most obvious use of the potentiometer which most of us have spotted is volume control in radios and other audio ...

1.2How to Connect a Pot using Two Leads 1.3What is the function of a Potentiometer 1.4What's a Preset How Potentiometers Work Potentiometers, or pots as these are called in short form are passive electronic devices which are basically just variable resistors, or resistors whose values can be...
3. How to Sweep Correctly This may be one of the best skills you can master if you’re going to own and use a metal detector. You’ll often see the terms sweeping and swinging used interchangeably. This is the action of moving the searchcoil side to side while you cover ground to de...
Use your phones application “frequency sound generator” (pick whichever you like best) as the source. Then connect the high frequency driver to an amplifier and the amplifier to your phone. Now use the application to sweep through the frequencies and try to hear different levels of loudness....
