Microcontroller-Based Speedometer-Cum-Odometer

Normally, digital speedometers are found only in luxury cars and high-end motorbikes. Even if your motorbike has a mechanical speedometer, what will you do when it gets damaged? First, you need to replace the mechanical worm gear and then the cable.

Anyway, we describe here how to build a digital speedometer-cum-odometer for your motorbike. The circuit uses a microcontroller, an LCD display and some commonly available components. It is a better
