Weekly Progress

Detail of week.

This week, I do PCB circuit cooker of Electric rice cooker. The circuit has Microcontroller AVR

ATMEGA128 and IC real time clock DS1307 and circuit POWER SUPPLY. Microcontroller has run clock

frequency 16MHz. So before use Microontroller set “fuse bit” to run external crystal frequency 16MHz. When

read signagure device of ATMEGA128 is “0x1E 0x97 0x02” for use external crystal run CPU. Next write

program to microcontroller and test program.

Figure 2. Set “fuse bits” of microcontroller in

program AVR studio Engineering Analysis Strong Point

- I learned about start use Microcontroller ATMEGA128 is set “fuse bits” and set Microcontroller run external crystal.

Week Point

- Lack of long testing time.

Next Week Job

- Must do Electric rice cooker complete.
