Been freelancing in mechatronics and embedded here in Syria. Most of what I build goes on GitHub with wiring diagrams, firmware, and code included. All of it is MIT licensed.

A few of the projects:

PyServoArm-6DOF. A 6DOF robot arm. Python GUI built with CustomTkinter talks to an Arduino over serial and drives 6 servos. The ESP32-CAM streams 640x480 video over Wi-Fi so you can watch what the arm is doing while you control it. Has mDNS auto-discovery, per-joint calibration, speed control. Arduino, Python, and ESP32-CAM firmware are all in the repo.

arduino-matlab-ultrasonic-radar. A 360 degree ultrasonic radar. Arduino mounts an HC-SR04 on a servo, spins it around, streams the distance readings over serial. A MATLAB GUI parses the packets, filters out noise, and draws a live polar plot. There's calibration for dead zones and beam spread too.

MATLAB-4DOF-RobotArm. A 4-axis arm you drive from a MATLAB keyboard GUI. Arrow keys and WASD move the joints, the GUI sends serial commands to the Arduino.

Revolving-Pyramid-Hotel. My BSc graduation project. IoT hotel automation built on a rotating pyramid model. Raspberry Pi does face recognition with OpenCV and runs a Telegram bot. Arduino handles the stepper rotation, PID solar tracking, RFID, and the flame and gas sensors. The two controllers talk over serial using JSON commands.

If you spot anything broken or have ideas, open an issue or send a PR. If you've made something similar I'd like to see it.
