• Touch Plate

The project introduces the concept of:

• Magnetic field detection

• Solar power generation

• Capacitive touch sensing

• Sound amplification

What is the function of the resistors in this circuit?

• To produce light

• To act as the touch input

• To indicate the switch status

• For voltage division and circuit stability

The Touch Plate, made of Copper or Aluminium Foil, acts as what?

• The main power source

• A touch-sensitive input

• The circuit's brain

• An indicator light

What is the purpose of the two LEDs in the circuit?

• To power the circuit

• To act as the main controller

• To indicate the switch status

• To sense touch

How does the 555 Timer IC get its name?

• From its 555 pins

• Because it was invented in the year '55

• From the three 5k ohm resistors inside it

• Because it consumes 555 watts of power

Which pin on the 555 Timer IC is the Ground (GND)?

• Pin 8

• Pin 3

• Pin 1

• Pin 5

Which pin on the 555 Timer must be connected to the positive (+) terminal of the power supply?

• Pin 1 (Ground)

• Pin 3 (Output)

• Pin 7 (Discharge)

• Pin 8 (VCC)

What is the function of the "Trigger" pin (Pin 2)?

• It stops the timer

• It provides the output

• It starts the timer when the voltage goes low

• It connects to the positive terminal of the battery
