7-segment displays comprise 8 LED elements – 7 linear segments that form numerals, plus a circular dot. Numbers 0-9 and some letters (A, C, D, E, F, H, L, O, P, U) are represented using combinations of the 7 lines. The dot creates decimals. Each element connects to a dedicated pin, allowing individual control. Pins […]

Introduction A microcontroller typically serves as the central “intelligence” of a mechatronic system, functioning as a miniature self-contained computer. It can be programmed to interact with both the system’s hardware components and the user. Even the most basic microcontroller can execute elementary mathematical operations, manage digital outputs, and monitor digital inputs. With the continuous evolution

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
