Re: Change size of root partition

Thanks for the replies.

I gave up with gparted. So I did sudo apt-get autoclean and it removed enough space so I don't have to change size of my root partition. Thanks !

Re: SN754410 not working

Great ! Thanks to asandford, I realized the bridge was not correctly connected to the breadboard (I didn't want to force it, but it really has to "clip" in it)

Thank you everyone !

Should I take a 4xAA batteries pack (for 6V) or a 9V battery, to power the motors?

Re: Controlling DC motor Using H-bridge

Yes, I mean these.

But the battery pack is for an arduino. Do you think it is possible to denude the cables of the battery pack so I can connect it directly on my breadboard?

Powering with USB hub

Hello,

I want to add a powered USB hub for my Pi, and power it with the hub. I was thinking of this hub.
Do I have to add a USB > Micro USB cable to power it?
