Temple three state logic ic CD4001

The work of the circuit be the circuit will use not gate IC in show supervision. In case of still have no input signal come in be liberate input pin of IC1/1 float keep. Which make have impedance very many, which have no LED anything shine come out.
In first condition, If input that come in be “0″ IC1/1 will get back to the position gives output be “1″ make , LED1 switch off . But LED2 the bright condition that pin 5 of IC1/2 be “1″ make pin 7 of IC1/2 be “0″ all the time cause IC1/3 and IC1/4 work give pin 11 of IC1/4 be “0″ make LED3 the bright.
If gush up that come in be “1″ IC1/1 as a result will get back to the position gives output go out be “0″ make LED1 bright the part LED2 switch off IC1/2 receive input be “0″ cause IC1/2 IC1/3 work be frequency signal generator circuit give IC1/4 for current driver give LED3 make LED3 flasher. But if input be pulse signal come in which have signal entireness low and high alternate make LED1 and LED2 stick alternate go to follow the speed of pulse that come in and LED3 condemn bright all the time.

Touch Switch using digital IC

If friends seek touch switch Circuit model to be simple. I begs for to advise this circuit, use integrated digital circuit number IC CD4001 perform be Schmitt Trigger , and the integrated circuit IC 4020 perform be two divider circuit. It is control electric appliances work with Relay by when we touch at the sensor point for the first time On,when press for the second time will Off Relay. For other equipment nothing is a lot of request friends , see in the circuit better.

Touch Switch By IC 4001 & 4020

Circuit Touch Switch By IC CD4001, CD4020
This be touch switch be simple again the circuit. It use integrated digital circuit is important equipment, and use volt power supply low just 9V. By use single metal, it works in the character turn ON and turn OFF. By when touch for the first time turn ON , but enough for the second time turn OFF. The circuit composes IC CD4001 take electric signal from a finger become the digital signal for change. The IC CD4020 be the counts two circuit or the divides circuit by two. Subsequently submit give the transistor drive Load next.
