I am very much interested in projects from my school life. When I was in class XII I participated in National Experimental Screening Test conducted by IIT Kanpur by HC Verma and I got selected as state level participator.
I secured 7th rank in Higher Secondary Examination.
I also had done some projects based on IOT and Analog Electronics.

1. I prepared one circuit which can control the signal transmission based on optical irradiance of proper wavelength.
2. I have made a project with Arduino Ultrasonic Sensor which measures distance by transmitting and receiving Ultrasonic sound . And programmed it that when the distance is below 50cm it will transmit it a digital signal to a bazar (Sound Speaker) like a warning label . It will also show me the graph of distance VS time . By which I can easily understand whether any particle is passing from the sensor.
3. I have made a project with Piezo Electric Sensor. When a pressure will be created on it the ions will move and create current but the current will be AC so I have rectified the AC signal to DC using bridge rectifier circuit . But the pressure will not be equal so the created AC signal will neither be Pulse signal nor any sin or cos wave signal . so the DC output will be disturbing . By connecting a capacitor with resistance (with time-constant less than the frequency of the signal) the output DC Signal becomes constant almost . Now this can be used as a current source as the current will be same .The voltage can be gained by decreasing the capacitance of the capacitor (as voltage proportional to 1/c ) and the current can be gained by connecting the AC signal with a Transistor in common emitter configuration.
4. Recently I build a Deep Neural Network Model on binary classification to train a set of data and optimized the cost using Gradient Decent method to approach the minima and to get better accuracy in test dataset.
   I am very much interested in Machine Learning , Deep Learning and AI.
