Digital speedometer and odometer circuit. US3477022A - Electronic speedometer and odometer control circuit - Google Patents

MikroC code would be preferred. C lector 70 of transistor T-S is connected through biasing resistor 72 to regulated power line 26 and to the anode of diode 74 and through a resistance 76 to the base 78 of transistor T4. Digital-Speedometer Softwares Used- References. Thus, transistors T-3, T-4 and T-S comprise a monostable multivibrator which provides a constant output pulse width over an input frequency range cycles per second. The circuit of the digital microcontroller based speedometer-cum-odometer is shown in Fig. We use Cookies to give you best experience on our website.

 

Digital Speedometer and Odometer Circuit using PIC Microcontroller Measuring the speed/rpm of a Vehicle or a motor has always been a.While verifying the working using a simulation software, the Hall sensor is replaced with a Logic state device.

 

Thus, the reading on the meter M-l indicates the momentary speed of the vehicle and acts as a speedometer. As for the odometer section, capacitor 80 is charged.Reply asap plz.

 

Feb 24, - In this project you will be able to calculate the speed and distances covered by any rotating object and display them on a 16x2 LCD screen.This meter or readout provides an indication of the momentary speed of the vehicle.

 

forum? This is a circuit for a microcontroller-based digital speedometer cum odometer for a motorbike that can display the speed and the distance.Truly Innovative Tech.

 

Digital-Speedometer This project includes a simulation model for the above idea. In a practical situation a hall sensor can be used to calculate the speed.The demo uses an's D-flash to read and write the odometer values.

 

Read it from here. This is a further development of that circuit. This circuit indicates both speed and distance. A speedometer or a speed meter.Distance: The odometer is updated every metres.

Condenser 50 recharges and the positive pulse across the resistor 52 turns transistor T-3 on.

 

We then use the help of timers and Interrupts on our PIC Microcontroller to calculate the time taken for one complete rotation of the wheel.

 

I am sure it would also work for a bike be it plastic or metal.

 

This can vary with the brand or model.

Once you build your project it should look something like this in the picture below.

The microcontroller takes care of the tasks of revolutions counting, speed calculation, conversion and display of results.

 

This circuit indicates both speed and distance.

 

I will be able to help only if I know what error you are facing.

If the mechanical drive shaft can be eliminated and an electrical conductiveconnection substituted, many difiiculties are overcome.

 

Even if your motorbike has a mechanical speedometer, what will you do when it gets damaged?

 

Before we actually start building the circuit, let us understand how we will be using a Hall sensor and a magnet to calculate the speed of a wheel.

 

First, you need to replace the mechanical worn gear and then the cable.
