I want to power a water pump with usb port but their voltages dont match. What should i do?
A friend of mine showed me a project in a magazine he thought it was really awesome and unusual but i knew i could make it. Although the mag didnt tell how it works i made a design in my mind. i need to power a water pump via usb. I can easily access a 12 volt pump and 5 volt usb but the usb voltage isnt sufficient. Can i find a lower voltage pump or increase the voltage of the usb, please help?
