Weekly Progress
On 21 March 2012, Today get to present with id group. About interface rive cooker is
capacitive touch switch with ic 555. 555 timer IC is an integrated circuit use in a variety of timer,
pulse generation. In the monostable mode, the 555 timer acts as a "one-shot" pulse generator. The pulse
begins when the 555 timer receives a signal at the trigger input that falls below a third of the voltage supply The
width of the output pulse is determined by the time constant of an RC network, which consists of a capacitor
10nF and a resistor 100 ohm Touch plate connect transistor 2n2222 and pin 2 is TRIGGER. When have
you touch at touch plate ic 555 will be trigger and on pulse. Pulse will send 5v to microcontroller.
Miccrocontroller is main part in the most impostane ricecooker.
Engineering Analysis
Strong Point
- Teamwork
- Thinking logically
- We have a good relationship
Week Point
- We don’ t have information about interface in rice cooker.
-
Next Week Job
Next week we Next week, we need to design the circuit complete.
