What you are seeing in the video below, it basically works like a projector, we have made this circuit in such a way that when the light does not go in the LDR, it turns on the inside light automatically, then the light inside it will light up again. Looks like eyes in the dark...
In this, we have used the components given below, if you want to buy these components, then there is a link with the name of the components, you can buy from that link -
LED - https://amzn.to/3mDYjdt
3v LED - https://amzn.to/3yrIdG2
3.7v Lithium Battery - https://amzn.to/3zsBCfU
Switch - https://amzn.to/3ksv0bc
LDR - https://amzn.to/3mGnrQR
BC547 Transistor - https://amzn.to/3gH60vM
this is its circuit diagram -
It will look like this after completion -
