Speedometer Cum Odometer

Digital speedometers are typically found in luxury vehicles and high-performance motorcycles. However, in the event of a malfunction in a mechanical speedometer, an alternative solution is necessary. This digital speedometer displays speed and distance in kilometers for both motorcycles and cars, while also providing data storage capabilities. The primary goal is to offer an economical solution for users.

The digital speedometer circuit can be designed using a microcontroller, which serves as the central processing unit for measuring speed and distance. The system can incorporate a hall effect sensor or an optical sensor to detect wheel rotation. The sensor generates pulses as the wheel turns, which the microcontroller counts to calculate the vehicle's speed.

The microcontroller is programmed to convert these pulse counts into speed readings, typically displayed in kilometers per hour (km/h). Additionally, the microcontroller can accumulate the total distance traveled by counting the pulses over time, allowing the speedometer to display both current speed and total distance traveled.

To enhance functionality, the circuit can include an LCD or LED display to present the speed and distance information visually. The display can be multiplexed to show different data such as average speed, maximum speed, or trip distance when buttons are pressed.

Power supply considerations are crucial; a voltage regulator can be used to ensure the microcontroller and sensors operate within their specified voltage ranges. A rechargeable battery or a connection to the vehicle's electrical system can provide the necessary power.

Furthermore, the design can incorporate user-friendly features such as a reset button for trip distance, backlighting for visibility in low-light conditions, and possibly Bluetooth connectivity to allow data logging and real-time monitoring via a smartphone application.

Overall, this digital speedometer circuit design provides a reliable and cost-effective solution for monitoring vehicle speed and distance, making it an excellent alternative for motorcycles and cars with malfunctioning mechanical speedometers.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, It is a digital Speedometer which shows the speed and Kilometers in motorbikes or cars and also save it. the main objective is that it is economical to use 🔗 External reference
