It it it's not a high voltage battery. Then also we can  If it is a rechargeable one , then uh people can use it for a long time , so in that way we can cut cut the cost , but w uh uh that we have to make the battery as rechargeable one. And we we have a circuit board uh in a remote controller. Can you go to the next slide , please. And how it works , how the remote controller works.
Go away.
Thank you. Uh when you press a button , when you do that , you complete a specific connection that means when you when you press a button there will be a s a small circuit underneath the button , and it will send some signals through the wires ,
and then uh the chip will send start connection and knows that which button is pressed. Suppose you have pressed channel one button , number one you have pressed , then the uh chip will know that the number one button was pressed.
