Water pump using 1 power source

[odyez]

I just tried to power the arduino with 5V powerbank by the VIN and as well to the Relay and It works without problems, i Know i Need higher Voltage for the arduino but I guess 5V will enough to power every thing on the board

I can use any of the Ac adapter that has 1mA will good I guess to run the whole project for long period of time

Yea I know how to solder and use a protoboard.

my queation is will that 5V damage anything for long run ? motor and other components are ok but the arduino the recommended is 7.5V and I know that it can work min on about 3.6V, and anyone has notes for what i am doing ? ( will add the 100 nF non polarized cap to the motor soon )

There is no guarantee that anything will work correctly or reliably if you violate the Arduino specifications. You are operating at your own risk

It cannot.
