1) Android Controlled Metal Detector Robot

Built using the 8051 microcontroller and the 555 timer IC for metal detection
The robot is designed using DC motors and the direction of DC motors will be controlled by the commands received from the android application.
The status of the robot is sent back to the Android app. This project also uses interfacing of HC-05 Bluetooth module with the 8051 microcontroller.
The metal detector consist of oscillator produces the alternating current passes throw the coil and producing alternating magnetic field.

2) Obstacle avoider robot using arduino

A simple obstacle avoider built with arduino and interfacing the L293d motor driver and an ultrasonic sensor

Built in collaboration with Akul Rattan, ECE : https://akulcv.imfast.io/
