In this project, we will create a straightforward alarm clock using the timers of the ATmega32 microcontroller. The ATmega32A microcontroller features a 16-bit timer, which will be utilized for tracking seconds and constructing a digital clock. Hardware components include the ATmega32 microcontroller, an 11.0592MHz crystal, two 22pF capacitors, a 5V power supply, AVR-ISP PROGRAMMER, a
1. Introduction 1.1 Problem Extreme cold temperatures, such as those experienced during the winter in Illinois, pose a significant threat of causing pipes to freeze and subsequently burst. Just this past winter break, our apartment complex sent out an email notifying residents on our floor that several units had unfortunately suffered burst pipes due to

During this week’s lecture, we delved into a relatively less-explored subject: USB, a widely-used protocol enabling computers to interact with peripheral devices equipped with microcontrollers. Developing a USB device empowers any computer to establish communication without the need for the specialized software and hardware that have been our focus thus far. For the next two

A Servo Motor is a type of DC Motor that incorporates error sensing negative feedback to precisely regulate the angular position of its shaft. Unlike standard DC Motors, servo motors do not rotate continuously but instead perform controlled angular rotations, such as 0-90° or 0-180°. While Stepper Motors can also achieve accurate angular rotations, Servo
