Examines the longevity and relevancy of the 8051 microcontroller for designing embedded systems in present applications. Includes extensive appendices for reference work. Encourages a hands-on, […]

Timer are widely used in industrial and domestic application for automating tasks. Microcontrollers can be used to design versatile and accurate timers with ease. Here I present a simple timer that can be used to turn on/off a load after user specified time. The Timer uses a standard 16×2 lcd module for user interface (UI). […]

Offering comprehensive, cutting-edge coverage, THE ATMEL AVR MICROCONTROLLER: MEGA AND XMEGA IN ASSEMBLY AND C delivers a systematic introduction to the popular Atmel 8-bit AVR microcontroller with an emphasis on the MEGA and XMEGA subfamilies. It begins with a concise and complete introduction to the assembly language programming before progressing to a review of C […]

This device can be used to remotely control the speed of an AC fan and to switch it on or off. The remote control is a cheap NEC Format remote, usually supplied with small DVD players. Three buttons are used to command the circuit. The UP key increase the fan’s speed while the DOWN key […]

How you can make a simple RPM Meter using AVR ATmega8. The RPM meter we will be making is a contact less type, i.e. it measures the RPM of a rotating object without actually making any contact with it. An IR reflectance sensor will be used to sense the speed. You have to attach a […]

Today, networking capability in one form or another- in particular internet accessibility- is becoming mandatory in many embedded applications, including home appliances, security, automotive design, and industrial control. Sophisticated networking and communications capabilities that were previously the sole domani of mainframes, PC’s and workstations are now moving into the realm of smaller embedded microprocessors and […]

This book is about the Arduino microcontroller and the Arduino concept. The visionary Arduino team of Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis launched a new innovation in microcontroller hardware in 2005, the concept of open source hardware. Their approach was to openly share details of microcontroller-based hardware design platforms to […]

Here is a project for beginners using Atmel AVR ATmega8. The project uses some techniques that are very useful for designers to learn and utilize. Alphanumeric LCD Module Interfacing. 4×4 Keypad interfacing. PWM Control of LED (Used to dim the back-light of LCD, like in some Nokia Phones) Basic Circuit design for AVR MCUs Connecting […]

The AVR RISC Microcontroller Handbook is a comprehensive guide to designing with Atmel’s new controller family, which is designed to offer high speed and low power consumption at a lower cost. The main text is divided into three sections: hardware, which covers all internal peripherals; software, which covers programming and the instruction set; Contents Some […]
