Story

Hello everyone !

My name is Adhrit Choudhary, I am 10 years old. I am a student of MECHATRON ROBOTICS, New Delhi. I have completed a fully fledged Arduino and Electronics course in just 2 months. I have always been fascinated towards Coding and Automation. I want to become a Pokemon Trainer, Hehe, I want to make my own Pokeball to catch pokemons. I know it sounds childish but i'm 10. I want to use Arduino programming to create a replica of Pokeball.I would also love to contribute towards the INDIAN DEFENCE SERVICES.

This project will help people withdraw cash from any ATM without actually making a physical contact with the switches. An ultrasonic sensor is used to provide input to the ATM Machine. For ex- If your input pin if 4578, then you will put your hand at 40cm, 50cm, 70cm, and 80cm for a moment of time. Depending on the distance, any person can input his pin. The buttons on the machine will be pressed by the Servo Motors attached.

This project can also be used to turn ON and OFF any switch at home or offices.

Looking forward for more innovative ideas at Arduino Project Hub.

Thanks Everyone !

Stay Safe and Happy !
