Universal Embedded Systems Learning Kit

All-in-one embedded learning platform supporting AVR, PIC, Arduino, and ARM — packed with modules and interfaces on a 4-wheel robot chassis for hands-on microcontroller programming education

Project Overview

Designed a universal embedded systems learning kit to simplify and accelerate the learning of embedded programming. The kit is compatible with four microcontroller families — AVR, PIC, Arduino, and ARM — and includes a rich set of onboard modules and interfaces so learners can immediately practice peripherals without any additional hardware. The entire kit is mounted on a 4-wheel robot chassis, allowing students to also run motion and robotics experiments in addition to standard embedded programming exercises.

Universal embedded learning kit mounted on a 4-wheel robot chassis — featuring Arduino Mega, DIP MCU socket (PIC/AVR), 20×4 LCD, 7-segment display, ultrasonic sensor on servo, 4×4 keypad, relay, motor drivers, RS232, and a central breadboard area for custom experiments.
