The weekly report discusses progress on an air purifier product. The engineering team found problems this week including a defective control board, LEDs that did not light equally, and an unresponsive touch switch. They worked to solve these issues based on circuit designs from another student. While the purifier circuits now function, uneven LED brightness remains a weakness. Next week's task is to present the completed product.

Weekly Progress
This week, It is last week to deliver a product but we found the some problem
such as the control board is defective, LEDs are not equal lights, the touch switch is not
working well. When the touch switch to work with microcontroller. But we try to solve the
problem. It is based on an ID student. I assembled the touch switch circuit and mood light
circuit in the air purifier.
