I have USB charger battery pack with two output ports (Fremo C510). One is marked as 5 volts 1 amp, and the other as 5 volts 2 amps.
I'm building a toy robot and would like to run the UNO off of one of those ports, and the motors off of the other.
Can I safely do that? I have two main concerns:
- Can I safely power the arduino with that current?
- If I power both the motors and the arduino from that source (two usb ports connected to the same battery), will I still have to worry about spikes from switching the motors on and off? I don't know how those ports are wired to the actual battery inside.
