Mm-hmm.
Uh a diode , a transistor , a resonator , these are all this uh technical uh electri electronic compons uh components which are  which we have to use in a remote controller. A battery uh , I would like to suggest one thing uh if we  uh if we will be able to make a res rechargeable battery then we sh we need not go for a high performance battery , even if it is a low performance battery it ca it can't l it can't charge much.
Mm-hmm.
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.
