Project 5 KC: Exploring e-Textile & Wearable Technology

What is the primary function of copper tape in your light-up bracelet project?

• To insulate electrical components

• To conduct electricity between components

• To provide structural support

• To decorate the bracelet

What does LED brightness depend on?

• The shape of the bracelet

• The color of the copper tape

• The strength of the battery

• The size of the circuit

Which component supplies power to the LED in the bracelet?

• Resistor

• Switch

• Coin cell battery

• Capacitor

Why is it important to connect the LED correctly in the circuit?

• LEDs are non-polarized components

• LEDs will only light up if connected with correct polarity

• Incorrect connection will make the LED change color

• It doesn't matter how LEDs are connected

What could be the reason if the LED does not light up after assembling the bracelet?

• The battery is inserted upside down

• The copper tape is not conducting electricity

• The LED is connected in reverse

• All of the above

What is the role of the insulating layer in the bracelet design?

• To prevent short circuits by separating conductive paths

• To enhance the bracelet's appearance

• To increase electrical conductivity

• To store electrical energy

Which material are commonly used as a conductor in e-textile projects?

• Plastic thread

• Rubber bands

• Conductive fabric tape or Copper tape

• Nylon strings

What is a common voltage rating for coin cell batteries used in light-up bracelets?

• 1.5V

• 3V

• 5V

• 9V

How can you test if the copper tape connections are working properly in your bracelet?

• Visually inspecting the tape

• Using a multimeter to check continuity

• Measuring the length of the tape

• Checking the color of the tape

Which part of the engineering design process are you using when your LED doesn’t light up and you adjust the copper tape to fix the connection?

• Brainstorm

• Redesign (Improve)

• Research

• Communicate
