How to Wire a Potentiometer as a Variable Resistor
A variable resistor allows for a portion of a circuit to have its resistance altered by the turn of a knob, useful for applications such as dimmer switches and temperature controls on heaters. Originally known as a rheostat, the variable re... Read More »

Which resistor or potentiometer to use?
Never heard of these before! It is probably driven by a solenoid. Reducing the supply voltage by some means will only slow down the frequency of vibration but it will still make the noise you wish to remove. If you slow it too much it will ... Read More »
