Uh which uh we can use a highly sophisticated one because it's like the it's like the heart of the remote controller. If it is not efficient then everything wi is going to be uh like um the lef ess less efficient so it  you should  we should have a highly sophisticated one. And it should be resistant to high as well as uh low temperatures. Suppose if it is thirty-eight degrees outside forty degrees outside , it should it should uh  be able to re uh resist the uh temperature uh uh highs and uh high temperatures and low temperatures. And uh it should be with uh  um  equipped with timer and alarm facility. And the uh other component we should  uh we have in the remote controller is a resistor uh which is like uh uh i it is very very much important for the electricity uh flow through  through through the uh remote controller and uh also a capacitor which is a b which is a m I think it's it's like a battery , capacitor. Can you go on to the next slide , please ?
Mm-hmm.
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.
