Switching the direction of DC current flow to a load

Question

I am a beginner (Software field) trying to do some basics in electronics.

I have got a load and a power source like this

My requirement is just to switch direction of dc current to the load in a controlled way.

I mean just switch the positive and negative to the load dynamically based on situation.

For example for few seconds current flows from left to right and for next second I need to switch it.

So in my code I am deciding how long and when to switch. I am using arduino.

And in my scenario its not actually just micro seconds sometimes, not even seconds a direction stays there.

How to achieve that?

@DKNguyen HBridge sounds awesome.. Thanks a lot for that.. I found a module. But that specific one only handles .8A which doesnt work in my case. So needs to find some modules more powerful Thanks a lot.. — Sandeep Thomas, Nov 25 '21 at 08:56

It's not clear from your question how fast you need to switch or how often but if the requirements are fairly slow then you could use a DPDT (Double Pole, Double Throw) relay.

I need to switch from one polarity to another in milliseconds or less.. But in one polarity it may stay sometimes little long (upto 4-5 seconds) and sometimes only few micro seconds – Sandeep Thomas Nov 25 '21 at 08:58
