Let us talk about how can we power Audrina?
So this is our Audrina bought, and actually we have two methods to do that.
First one is by blocking your USB cable in the USB port here.
And connecting it to your PC and you would need this stage right here if you want to program your Arduino.
So in order to download your sketch to Audrina, you need to plug in this USB cable.
Your Dwina would be powered.
And also there is a new A.R.T. protocol are running on this USB so that you can program this sport.
Now, let's say that you don't want the power to the USB, but you want a power grid where the power
supply.
Well, you can get the power supply in the range between to between nine and 12 or even seven and 12
would work.
And you would connect it to an electrical socket and then you would have your ordering a about up.
But it's not really recommended that you connect these two together because it might create some issues
in your power and it might burn up your.
Oh, no.
So it's not really recommended to do that.
If you want to download your sketch, you just unplug your power supply here and just plug it from USB.
It will be powered up.
And your thumbnail sketch, if you want to take your Arduino and connected someone somewhere else away
from your PC and still be able to run all the stuff on their Adreno, you could just plug in your power
supply.
Now, let's say that you want a prototype and you have a bunch of sensors that need both apply and let's
say that you don't have a power supply.
How can you power your sensors?
Because sensors usually have three pins.
Two of them are for power and one of them is for signal.
So two of them would be four, five votes and the ground and the other one would be for your signal
in order to get a signal so you could use your breadboard right here in order to distribute power to
a component.
So if you take your five volt and connect it to the plus your agenda to the minus, then you can take
it from these points and connect your sensors.
You could power up your sensors with power using these so you don't have to actually take a power supply
connected right here by your sensors and then do a common ground in between.
But all you can do is just take the five volts here and the GENNDY and distribute it to a breadboard
and then your sensors will be powered up.
