This weekly report summarizes the progress of an engineering student group called KID-WA Company. The group met with their teacher this week to discuss another student group's project involving a violent microwave design. The report discusses RGB LEDs and how different colors can be created by adding red, green, and blue light. Creating the color orange from an RGB LED is identified as a weakness. Next week, the group plans to design a circuit for a refrigerator.

Weekly Progress
Overall: This week, we met teacher for ID student presented about their model of works. They had a
problem with microwave theirs will be sending microwave that will be violent for human.
Engineering Knowledge: This week I search about RGB LED. The RGB color model is an additive color model
in which red, green, and blue light is added together in various ways to reproduce a broad array of colors. The
name of the model comes from the initials of the three additive primary colors, red, green, and blue.
The main purpose of the RGB color model is for the sensing, representation, and display of images in
electronic systems, such as televisions and computers, though it has also been used in conventional
photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in
human perception of colors.
Figure 1. ADDITION COLOURS Engineering Analysis
Strong Point:
- IT is easy to make many colors from 1
LED.
Weak Point :
- We want orange color but it is hard to
make this color.
Next Week Job
We should design circuit for refrigerator.
