This course offers a thorough introduction to embedded systems and their applications, starting with fundamental concepts and progressively moving to advanced topics. Beginning with an overview of embedded systems architecture, design principles, and real-time operating systems, you will gain a solid foundation before delving into microcontrollers and their significance. The course then transitions to practical applications with the Arduino board, covering everything from basic LED programming to complex sensor interfacing and data communication. Throughout the course, you will explore various interfacing techniques, including LED, buzzer, switch, serial port, and LCD. You will also learn to handle analog inputs, use sensors like LDR, ultrasonic, and temperature sensors, and understand advanced concepts like PWM and I2C communication. Each section is designed to build your practical skills, culminating in exciting projects such as a USB 3D air mouse and digital voltmeter. By the end of the course, you will have a comprehensive understanding of how to integrate hardware and software for innovative embedded system solutions. With hands-on projects and detailed explanations, you will develop the expertise to tackle real-world challenges and create sophisticated electronic devices.
