Top 8051, AVR and ARM Microcontroller Based Projects for Electronics Professionals

Microcontroller, as the name suggests, is a small controller. It is like a single-chip computer, which is embedded into other systems to work as a processing and controlling unit. A Microcontroller communicates with other devices like sensors, switches, keypads, etc. Most of the microcontroller-based projects use 8051 microcontroller, and the microcontroller programming is done by using Keil compiler. For low-cost and low-powered embedded-systems-based applications, these microcontroller-based projects are the best choice.Top 8051 AVR and ARM Microcontroller Based Projects for Electronics Professionals

Microcontrollers are classified into five types based on the instruction bits, memory architecture, architecture of the instruction set, and memory devices: 8051 microcontroller, AVR microcontroller, ARM microcontroller, PIC microcontroller and RENESAS microcontroller. The following are some of the microcontroller-based projects on 8051, AVR, and ARM for electronic professionals.

AVR Microcontroller Based Project

AVR microcontrollers are RISC based controllers, manufactured by Atmel group. They consist of built-in features like timers, analog to digital converters, etc. Different AVR microcontrollers are ATMega8, ATMega32, and ATMega328. ATMega8 is a 28-pin microcontroller with an 8KB of programmable memory and 1536 bytes of data memory. ATMega32 is a 40-pin microcontroller with 32-programmable input or output lines. ATMega328 is a 28-pin microcontroller with a program memory of 32KB and data memory of 3KB.

ATmega Based Garage Door Opening

This electronics kit based project is designed to unlock a garage door by using Android application with a unique password. Opening and closing of garage door involves a human labor, but in this project, automatic mechanism is done by using Android application. An Android application-based mobile is connected to the system through a Bluetooth device, which is attached to the microcontroller and programmed with the unique password for opening and closing of the garage door by its owner.

Remote operation is performed by using any Smartphone, tablet, etc., with an Android OS upon graphical user interface based touch screen operation. A Bluetooth modem is attached to the receiver end of the microcontroller. If the sent data matches with the password stored in the microcontroller, then it performs the mechanical operations to open and close the door through the relay operated motor. This system uses a lamp in place of a motor for visualization purpose. If the password is correct, then the lamp will glow, and if the password entered is wrong, the system generates a buzzer alarm.

In this project, an ATmega microcontroller is used as a main controller and is programmed by Arduino programming language. This microcontroller allows the Bluetooth modem to interface with it. Some more projects related to AVR microcontroller are given below

ARM Microcontroller Based Projects

ARM microcontrollers are based on advance RISC-based processors. These are 32-bit microcontrollers and can be operated in two modes: thumb mode and normal mode. The ARM microcontroller families include ARM7, ARM9 and Cortex.

ARM Cortex (STM 32) Based Motor Speed Control

This project uses an ARM-cortex processor to control the motor speed. The speed of the DC motor is directly proportional to the voltage applied across the terminals. If the voltage applied across the terminals varies, then the speed of the DC motor also varies. This concept is implemented in the ARM-cortex microcontroller using PWM technique.

Push buttons are used in this project to vary the speed of the motor – either to decrease or increase the speed. The switch pressing depends on the pulse-width modulation technique to vary the voltage to the motor. A motor driver is used in this system for driving the DC motor and to control it in either direction.

When a switch is pressed, the microcontroller receives the signal – and, based on the programming, it sends the PWM signals to the motor driver which further drives the motor in desired speed.Top 8051 AVR and ARM Microcontroller Based Projects for Electronics Professionals schematich

ARM Cortex (STM 32) Based Solar Street Light

This project is designed to control the auto-intensity of LED based street lights using the solar power from photo voltaic panels. Solar panels are used for charging the batteries which converts sunlight into electricity. A charge controller circuit is used to control the charging process of the battery, and it also protects the battery from over-voltage and under-voltage conditions.
