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 […]

OBDII Code Reader

November 09, 2010 By: admin Category: Automotive, AVR, Microcontroller, Project No Comments →

The ODBII Code Reader is AT90CAN128-based automotive tools that can read the ODBII protocol data and tell you which car system malfunctioned; it can also clear the code, which turns off the Check Engine Light. But most importantly, the ODBII Code Reader can tell you when the computer has rechecked the systems and reset their […]

Vehicle Blind Spot Detection System

October 25, 2010 By: admin Category: Automotive, AVR, Detector, Monitoring, Project, Sensor No Comments →

The In vehicle blind spot detection system (IVBSDS) helps driver to monitor the blind spots of the vehicle while driving in the high-speed lane. The ATmega169-based system use of the high intensity Infrared ray (TSOP 1738) to detect presence of any approaching vehicle. To avoid any false detection, infrared diodes transmit 36 KHz pulse. Thus […]

Fiat Car ECU Monitor

October 21, 2010 By: admin Category: Automotive, AVR, Monitoring, Project No Comments →

This ATmega32-based project allows the owner of a Coupé Fiat – produced between 1993 and 2000 – to interrogate the engine control unit while the vehicle is in use. In essence, it reproduces most of the functionality of a commercial ECU code reader but is integrated into the vehicle. It can also be used in […]
