  Automatic Disinfectant Spraying Machine Abstract — Viruses such as COVID-19 are transferable through touch and contact. There are WHO guidelines to clean or sanitize places regularly to reduce the risk of infection. Dispensing of sanitizer from the bottle and storage would require manual intervention. In this paper we propose a novel design of touch-less disinfectant spraying machine to reduce the risk due to contact. The system consists of live streaming and controlling it from an end user. The controller processes the sensor data & actuates the pump and solenoid valve. The sanitizer liquid dispenses through the mist nozzle and sanitizes the whole place accordingly. Keywords— Disinfectant, Sanitization, COVID-19, Automatic machine Introduction Hygiene is an important aspect to remain healthy. There are various aspects of hygiene. A clean place is one of  them.  COVID-19 began to spread from the year 2019 and the pandemic has been ongoing for several months. As the ...

Smart Glasses

Image
  An idea inspired from google glasses we tried making one using Arduino Nano and other such components, the device is capable of connecting to  the smart phone via Bluetooth using Bluetooth module  and display incoming calls, notifications and time  for the same. The  device  was then mounted on a simple glass converting into  a glass which can connect to your smart phone and thereby to the glasses, the programing was done in c and executed using Arduino ide. The application installed in the phone are given below.  Component: Arduino Nano OLED Display .96 inch Bluetooth Module: HC-05 Power Supply Connecting Wires Vibrator Motor   Circuit Diagram: Working:                                                                         ...
