Portable Ventilator

Very sorry for the delay to all people who are in need. Since under lockdown codition, I was only able to design the 3D, PCB and write the Arduino code (warning: code not tested). But could not test the same as I currently do not have NMEA17 motor nor the 3D printer. So this ventilator is portable ball valve mask type and with just few modification can be used to operate two of them in case of emergency. This is the only thing (knowledge) what I can currently give/contribute to the world and people from all countries who have been worst affected like Spain, France, Italy, Germany & other countries including the people from my own country India because of COVID-19.
