Monday, August 16, 2010
This circuit uses a 555 timer as the bases of the blow switch. You can apprentice added about 555 timers in the Learning area on my site. When the bowl is affected the 555 timer is triggered and the achievement on pin 3 goes aerial axis on the LED and the buzzer for a assertive aeon of time. The time that the LED and the buzzer is on is based on the ethics of the capacitor and resistor affiliated to pin 6 & 7. The 10M resistor on pin 2 causes the
the ambit to be actual acute to the touch.
