Arduino Motorcycle Control Panel

February 18, 2013 By: admin Category: Arduino, Measurement No Comments →

This motorcycle control panel is built based on Arduino. It works as motorcycle speedometer, tachometer and gear indicator. It read pulses from bike’s tachometer circuit and reed switch senses wheel rotation. At each wheel pass it calculates wheel speed in RPM and then divides that into the most recent engine RPM. The ratio is unique […]

This project allows you to monitor your bike riding speed and display it on LCD 16×2 mounted on handlebars. The project is built based on Arduino. It uses a magnetic switch/reed switch to measure the speed of one of the bike’s wheels. This simple speedometer should work with any kind of bike/wheel, just simply enter […]

Datsun Digital Speedometer

November 26, 2010 By: admin Category: Automotive, Digital, Project, Sensor No Comments →

This digital speedometer project was built to replace unreliable analog speedometer of 1971 Datsun 1200. The circuit uses digital IC like 555 timer, 4017 CMOS decade counter, 74C14 hex schmitt trigger inverter, 4553 CMOS 3-digit BCD counter and IC6 4511 seven-segment decoder/driver. This car speedometer project is equipped with two strong magnets to the tailshaft […]
