Remote controlled audio/video switching is not a new concept, but modern microcontrollers allow designers to incorporate functionality that was quite difficult in the past. Specifically, it is now possible using microcontrollers equipped with EEPROM and SRAM to capture IR signals and store their timing data for use as reference profiles that allow the device to respond to any compatible remote control transmitter the user may wish to utilize."The concept is fairly simple. A signal is detected, captured to SRAM, trimmed as needed, and finally stored to an EEPROM location that ...

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 the system will not detect any external light source and any other heat source.During detection process, two high intensity pulsed infrared beams are projected at the both left and right sides of the vehicle. The ...

The project shows you how to build digital clock based on microcontroller ATtiny2313. The time is displayed in the format "hh: mm: ss" on the alphanumeric display LCD of size 16 x 2 with driver HD44780. The 16 bit internal counters interrupts of MCU is used to generate time (1 interupt = 1 second). The clock has accuracy of +1 second / 48 hours.User can adjust the digital clock using 3 button : SW1 for setting hours, SW2 for setting minutes, SW3 to go mode of setting time and allows ...

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 other Fiat/Alfa/Lancia group vehicles using the same ECU hardware. To deal with the engine types most commonly used, the project must communicate with two different ECU types with non-compatible communications protocols. It should be noted ...
