Weekly Progress
This week we make the PCB circuit board. The circuit has Microcontroller AVR ATMEGA128 and
IC real time clock DS1307 and Power Supply and I try the touch switch circuit board. I found
problem that the touch switch circuit board, when used in combination with microcontroller circuit
board it's not stable. I think that the current supply to the circuit, there is not enough. I change
touch switch to micro switch in rice cooker's P'ID. It's stable.

Engineering Analysis
Strong Point
The output of circuit has a Logic it’s easy to use with a microcontroller.
Week Point
The current supply to the circuit, there is not enough.
Next Week Job
I will design new PCB touch switch circuit board complete.
