Abstract:

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 micro controller, an LCD display and some commonly available components. It is a better alternative to the mechanical speedometer and even a beginner with minimal skill level can assemble it. The features of the digital speedometer-cum-odometer are:1. Digital readout 2. Speed displayed in km/hour 3. Distance traveled displayed in kilometers 4. Readings saved in non-volatile memory (EEPROM) 5. Reliability due to use of the micro controller 6. No mechanical wear and tear 7. Home-brewed speed transducer/sensor 8. Self reset to zero after completion of 99,999.9 km 9. Easy to build and fix onto the bike Calculations: You first need to know the radius of the bike’s front wheel. The calculations here are based on Hero Honda’s Splendor model. The radius of the front wheel is 30 cm. (This can vary with the brand or model.) Circumference of the wheel= 2πr (where ‘r’ is in cm) = 2×3.14×30 = 188.4 cm or 1.884 meters Speed. Let’s assume that in 1 second the wheel completes one revolution. In other words, in one second, the bike has covered 1.88 meters. Therefore the speed in km/hour: N×1.88×3600/1000 = N×6.784 or N×6.8 where ‘N’ is the number of revolutions per second. ‘6.8’ is a constant and only ‘N’ varies; for example, if ‘N’ is 5, the speed equals 5×6.8= 34 km/hour. Distance. The odometer is updated every 100 meters. To cover 100 meters, the wheel is required to make approximately 53 revolutions (100/1.88). The micro controller takes care of the tasks of revolutions counting, speed calculation, conversion and display of results.

Hi friends
First of all, we thank you because you may have used our website below.
We are happy to tell you that Techsodes Corporation has created the microcontroller open source code editor named as MikroStudio IDE first time in India. This software is a power full tool for code development of microcontrollers like 8031, 8032, 8051, 8052, Mcs51, AVR, PIC, STM8, Z80, EZ80, Z180, padauk, rabbit and gameBoy etc. It is absolutely free and is also better than other programmable software or IDE (Integrated Development Environment) because they can programmed only few microcontrollers. MikroStudio IDE has been support 3000+ microcontroller without installation other cores or plugin. MikroStudio IDE used sdcc, avr-gcc and gputils compilers. MikroStudio IDE has also provides you an open source hardware and software community where you can discuss your problems with us and that problem will be solved by the community.
