The AVR microcontroller is an advanced RISC (Reduced Instruction Set Computer) 8-bit microcontroller developed by Atmel in 1997. Known for its high-speed performance and efficiency, it is widely used in various applications such as computer peripherals, industrial real-time control systems, instrumentation, communication devices, and household appliances. This article explores industrial electronic design solutions based on the AVR microcontroller, including projects like robots, smart cars, and more.
One application discussed is a fire-fighting robot designed using the AVR microcontroller. Based on competition rules, this robot uses the ATmega32 as the central controller and small DC motors for movement. It is cost-effective, easy to build, and can be adapted for other competitions with minor modifications. This makes it a great project for students and engineers interested in robotics and automation.
Another project involves an energy-saving elevator system controlled by an AVR microcontroller. By integrating group control and distribution algorithms, the system optimizes energy usage. If no one calls the elevator for three minutes, it automatically turns off lights, fans, and reduces display brightness, significantly lowering standby power consumption. Additionally, the system monitors elevator status in real-time, predicting and alerting potential faults to enhance safety and reliability.
A high-precision position control system for linear switched reluctance motors is also covered. Unlike traditional linear actuators that require gear or screw mechanisms, these motors directly provide linear motion, reducing costs and improving energy efficiency. With high precision and strong adaptability, they are ideal for high-accuracy machining and power transmission systems.
In agricultural applications, an AVR-based lighting and COâ‚‚ control system for watermelon greenhouses was developed. Using the ATmega16 microcontroller, the system integrates light and COâ‚‚ sensors to automatically regulate greenhouse conditions, ensuring optimal growing environments and improving crop yield and quality.
An intelligent teaching unmanned vehicle control system is also described. Built around the Atmega128 microcontroller and wireless communication modules, the system allows for precise control of the vehicle from a PC interface. This makes it a valuable tool for educational purposes, enabling hands-on learning in autonomous vehicle technology.
The paper also discusses a general-purpose AVR microcontroller-based control system. By creating a menu tree structure, developers can easily manage multi-channel input/output systems. This approach simplifies program development, maintenance, and future expansion, making it suitable for a wide range of industrial applications.
Lastly, an electric scooter controller based on the AVR microcontroller is presented. The design retains the mechanical structure of traditional wheelchairs while adding shock-absorbing components for better comfort and stability. This makes the scooter user-friendly, portable, and ideal for personal mobility solutions.
