Preset Pot


The preset potentiometer module supplies an analogue signal which, for simple applications, can also be interpreted as a digital signal.   It is very useful for setting variable values in a programme. When the preset control is rotated anti-clockwise, it outputs a high signal.  When the preset control is rotated clockwise, it outputs a low signal.  At intermediate positions, the module outputs a voltage roughly proportional to the amount of rotation.  Used digitally, the point at which the output signal changes between high and low is approximately at half rotation.
