Weekly Progress
This week we made about the touch switch circuit and the mood light circuit. The touch
switch circuit make by IC WB2080A. we chose to use IC WB 2080A because It is a touch pad
detector IC which offers 8 touch keys but we use 4 touch keys Applied to 4 modes . The touching
detection IC is designed for replacing traditional direct button key with fixed pad size. Low power
consumption and wide operating voltage are the contact key features for DC or AC application.The
mood light circuit make by LED. It has a brightness controls by Pulse-width modulation (PWM). The
PWM is signal of microcontroller The PWM is signal of microcontroller.It have duty cycle since 0%
to 100%. And we connect the output of IC WB2080A to microcontroller. I find that circuit. It can
work very well.
Figure 1. WB2080B Touching IC Figure 2. Test circuit
Engineering Analysis
Strong Point
I think that the IC WB2080A, It can working in product that use interface by touched.
Week Point
The IC WB2080 has to interference signal and it is hard to make with PCB because it is surface
mount.
Next Week Job
Next week, I will make a PCB of touch switch and mood light.
