CMOS 4013 Switch

Wednesday, July 30th, 2008


The voltage generated by a piezo transducer can activate a digital circuit. One may build a simple demonstration switch from a piezo transducer and a 4013 D type flip flop (see Figure 12). Each time the piezo film is hit, it triggers the 4013 turning the LED on and off on alternate triggers. While this [...]
