  • paper
  • battery

Step 1: Sketch out your circuit trace on a piece of paper

Step 2: Tape out any components you will need onto your paper. (P.S. Attach the end of one wire to one side of the battery, making sure that the wire maintains contact with the metal of the battery. Repeat with the other wire on the other side of the battery.)

Step 3:  The LED should light up because you have created an enclosure circuit.

 

Part 2

In this lab, we were tasked with building LED circuits in series and parallel. I learnt about that components in series have same current with one resistor, while those in parallel divide the current and have two resistors. The voltage in parallel is the same while voltage drops components in series.

Series circuits

 

Parallel circuits

 

The calculations required for both series and parallel circuits are pictured below

Part 3

Last part of lab, I chose to rebuild series circuit on proto-board. This was a whole new experience for me because I got a chance to learnt how to do soldering. The experience was quite difficult for me at first since I never done this and it took some time to get the parts connecting properly.

 

As for as an interactive idea I could think of is color lighting changing. There could be a touch function added to it. when your hands touch the LEDs around it and the LEDs could change color based off your hands temperature. Another idea is making musical sound when touching the LEDs. You could make your own music by touching the LEDs or you could touch another LED which randomly select music for you.
