Uh and uh  ,
Mm-hmm. Good point.
yeah , and also uh using of colouring compon components like uh if we want to have different colours , blue , red , green , so uh uh we have to use uh some colouring compone compone components. And uh the second important thing is uh uh uh integrated circuit.
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 ?
