'Datasheet' is the manufacturer's information relating to the device/circuit/component.

without this capacitor can i run this voltmeter?

474 means 470000 pF, i.e 470 nF, which is what you want. 100V rating is greater than the voltage your circuit uses so is fine.

Pictures of your breadboard don't help us. There must be a wrong or missing connection somewhere, or a dead component. Breadboards of poor quality give unreliable connections.

Sorry, I don't have the circuit diagram. The video showed nothing useful.
Google 'DC DC boost converter schematic'. There are loads of circuits out there.
