LED : Light emitting diode
LED : Light emitting diode
LEDs are output components that give out lights. Unlike an ordinary light bulb, LED has polarity and needs to be connected in the right way for it work light up. It uses very little current and generate very little or no heat. LED comes in variety of colors.
Switches are electronic components that can be used to make or break a circuit. A simple switch consists of two contact. When they are connected, the circuit is turned on, when they are disconnected, the circuit is turned off. Some switches are incorporated into a battery holder.

Act 4:
Design Situation
The class has decided to do a VIA project in the upcoming overseas learning journey to Cambodia. In to bring joy and laughter to underprivileged children from a rural village in Cambodia, the class has decided to design and make some mechanical linkage toys as part of their VIA activities during their overseas trip. You are tasked to design an electronic wearable toy for students in these rural villages.
Design Brief
To design and make an electronic wearable toy for children 13 to 16 years old so that it can bring joy to children from the underprivileged neighborhood as part of the VIA project.
Design Specifications
1. The electronic wearable toy must be made of acrylic
2. The electronic wearable toy must have a design theme of transport or superhero
3. The electronic wearable toy must have at least one led and a coin cell battery
Ideation : Shape borrowing
Every design starts with an idea. Based on your research, and block diagram, ideate using 2D sketches to show how your mechanism should function and design theme shown. Your task should show the following.
- Considering relevant factors when generating and developing ideas
- Sketching to design (2D)
- Complete 18 designs using the underlay provided
Act 5: Development
Act 5: Development
From your 18 design, choose one for further development. You will need to do the following:
- Refer to the sample below, design your LED circuit and draw your design below.
- Using cardboard, paper clip, led and copper tape, built your mock-up circuit and past it in your journal.
- Draw your production flow chart and production plan.
- Paste your mock-up in your design booklet.
Act 6: Prototype of your wearable toy
Act 6: Prototype of your wearable toy
In Act 6, you will need to build a prototype of your mock-up using the following
- Acrylic, switches, wires, CR2032 battery and LED.
Refer to the following video for practical process
