bicycle speed indicator circuit explained


Posted on Feb 6, 2014

The article presents a circuit that can be used for indicating the riding speed of a bicycle. The circuit of a bicycle speedometer explained here uses ordinary components like transistors and LEDs and yet succeeds in displaying a distinct 10 step, accurately calibrated linear reading, corresponding to the instantaneous speed of the bicycle wheels. The source is basically derived from a dynamo that generates electricity levels directly proportional to the speed of the bicycles rotating wheel, this varying potential is translated by the circuit into the corresponding reading through the illuminated LEDs..
