Q & A

What is the primary objective of the project presented in the video?

The primary objective of the project is to create an interactive display using LEDs and switches to understand even, odd, and prime numbers.

Why is it recommended to use a push button with a cap for this project?

It is recommended to use a push button with a cap because it makes the project easier to assemble and handle, ensuring that the switch is easy to press and install.

What is the purpose of using a multimeter in this project?

A multimeter is used to check the connectivity of the switch points, ensuring proper connections before proceeding with the wiring.

How is masking tape used in this project?

Masking tape is used to secure switches on the back side of the box, increase the strength of connections, and ensure that the switch pins hold properly in place. It is also used to cover wiring connections for safety and neatness.

Why is it important to use different colored wires for the LEDs?

Different colored wires are used to distinguish between the even, odd, and prime number connections, making it easier to follow the wiring and ensure the correct setup for each display.

What material is suggested for the number displays in the project?

Thin cardboard, or a 300 GSM drawing sheet, is suggested to create the number displays, which are then cut out to show the words 'Even', 'Odd', and 'Prime'.

What is the function of the diodes in this project?

The diodes are used to regulate the flow of current to the LEDs, ensuring that the correct display (even, odd, or prime) is lit up when the corresponding switch is pressed.

How is the positive and negative connection for the LEDs managed in this project?

The positive connections for each LED are made with different colored wires (green, red, etc.), while the negative terminals of the LEDs are connected to a common black wire, which is then connected to the negative terminal of the battery.

Why should you check the project during assembly?

It is important to check the project during assembly to ensure all connections are correct, and the LEDs light up as expected, preventing the need to reopen and adjust the setup after finalizing.

How is the battery connected to power the circuit?

The battery is connected by joining the common positive wire (white wire) from all switches to the positive terminal of the battery and the common negative wire (black wire) from the LEDs to the negative terminal of the battery.
