Embedded Pool is an intensive project aimed at learning embedded programming using a development board created by 42Chips featuring an ATmega328P microcontroller. This project, which spans over two weeks, involves studying official documentation of the microcontroller and various peripherals, understanding the schematics of the board, and mastering several communication protocols.
Each day, we focused on a new aspect of the development board, culminating in weekend rush projects that required quick thinking and teamwork. This README provides a detailed overview of the project, what was learned each day, and the overall objectives achieved.
Through the Embedded Pool project, I enhanced my skills in the following areas:
- C Language Proficiency: Improved understanding and practical application.
- AVR Microcontroller Development: Building and flashing code for the ATmega328P.
- Microcontroller Functionality: Insight into how microcontrollers operate and communicate using protocols like UART, I²C, and SPI.
- Teamwork: Significant improvement in collaboration and teamwork.
- Bitwise Operators: Real application and understanding of bitwise operations.

Day 09: 7-Segment Display
- Objective: Use an I2C 16-Bit I/O Expander (PCA9555) to display the value of the potentiometer.
- Skills Learned: Interfacing with I/O expanders, driving a 7-segment display.
Rush 01: Final Boss
- Objective: Combine all learned skills into a single program that can switch modes with a button press (e.g., display temperature, read ADC, light up all RGB LEDs, etc.).
- Skills Learned: Integration of various modules, complex program design, mode switching.
