Working with AVR microcontroller Communication Port Project

Leave a Comment / Other Projects /

Back in the old days the COM port or known as RS-232 (EIA-232 standard) is one of the essential communications protocol and hardware use in many computer system installation start from small UNIX machine to the mainframe. The RS-232 protocol is used by terminal such as wyse60 or DEC vt100 which connected through direct cable

UART Communication Between Two ATmega8 Microcontrollers

Leave a Comment / AVR ATmega Programmers /

In this tutorial we are going to establish a serial communication between two ATMEGA8 microcontrollers. The communication established here is UART (Universal Asynchronous Receiver Transmitter) type. By this serial communication data can be shared between two microcontrollers, which is required in various embedded systems. Components Required Hardware: ATMEGA8 (2 pieces), power supply (5v), AVR-ISP PROGRAMMER, 100uF capacitor

Acoustic Data Modem Using Atmega644

Leave a Comment / Interfacing(USB - RS232 - I2c -ISP) Projects, Other Projects /

Introduction For our final design project, we designed and built a prototype acoustic modem to serve as a physical transport layer for digital communications. It converts between a digital communications scheme (RS-232) and an acoustically coupled communications scheme of our own design. Our project consists of a pair of such modems to operate as transmit/receive

Ultrasonic Haptic Vision System using Atmega644

Leave a Comment / Sensor - Transducer - Detector Projects /

Introduction The ultrasonic haptic vision system enables a person to navigate hallways and around large objects without sight, through the use of an ultrasonic rangefinder that haptically interfaces with the user via tiny vibrating motors mounted on the users head.  The idea behind this project was to construct a sixth sensory system that interacts with

ODB-II Automotive data interface using Atmega644

Leave a Comment / Interfacing(USB - RS232 - I2c -ISP) Projects /

Our goal for this project was to build an OBD-II compliant device that would communicate with any OBD-II enabled car and read back real time data as well as perform basic performance testing and diagnostics. If you’ve ever had to take your car into the shop because of the dreaded “Check Engine” light, you can
