A collection of Arduino-based projects developed during my internship, including voice-controlled home automation systems and an ultrasonic distance meter with Proteus simulations.

This bot is controlled by an Android app which sends commands via Bluetooth. Servo motors control a three-axis robotic arm to perform pick-and-place operations. The project simulates a basic robotic ...
