A prototype of the system has been successfully fabricated. An alternative way of viewing the recorded attendance is by using HyperTerminal software.

The system can be connected to the computer through RS232 or Universal Serial Bus (USB) port and store the attendance in a database. Its ability to uniquely identify each person based on their RFID tag type of ID card make the process of taking attendance easier, faster and secure as compared to conventional method. It also can be used to take attendance for workers in working places. This system can be used to take attendance for a student in school, college, and university. More details about this project are available at: ultrasonic radar model. Air traffic control uses radars to track aircraft on the ground, in the air and to guide planes for smooth landings. Radar systems have a number of defense as well as civil applications.

The receiver receives and processes the reflected signal to provide such information like the presence of a target, distance, position (moving or stationary) or speed, which is displayed on a display unit. Ultrasonic Radar Mode Using Microcontroller ATmega128Ī radar system consists of a transmitter, transmitting a beam towards a target, which is reflected by the target as an echo signal. This value is further processed into information by an electronic display.ĭetails about the project are available at: digital soil moisture meter. These probes act as sensor elements that register moisture and change it into an electric value. This project monitors soil moisture content in irrigation farms by measuring the resistance to the flow of electric current between two metallic probes. As crop production requires water at different stages and in different amounts, it is important to measure soil moisture from time to time. AVR Projects: Digital Soil Moisture MeterĪ soil moisture meter is used for indicating the water content of a given soil sample. Let’s take a look at few interesting AVR projects.

These special features help students, hobbyists and engineers make innovative AVR projects.
#Lm35 codevision atmega16 series
These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. ATmega series are one of the types of AVR microcontrollers with features like 4–256 KB program memory, 28–100-pin package, extended instruction set, and extensive peripheral set. AVR is a family of microcontrollers developed by Atmel beginning in 1996.
