A Schmitt trigger circuit shows two distinct signal input levels for turning the circuit ON and OFF.The difference between the Von and Voff voltages called hysteris Schmitt triggers are useful in conbverting slowly rising waveforms into fast rising ones and in relay like application.
The circuit shown here uses a 741 with positive feedback via R5,R6 [...]
This be simple bounceless switch circuit, In the character electronic switch a kind is one. That be of good quality tall and low noise convenient for the digital. If switch usual apply to digital circuit like to to get into trouble promise disturb easy. It make the circuit works can make a mistake. This circuit [...]
This is a circuit diagram showing the random nature of LED 7 segment. In the diagram circuit IC1 – LM555, R1, R2 and C2 on the circuit a sensitive multi-Stable Brett Foster (Astable. multivibrator circuit) function generator signal square (Square Wave) and send the pin 3 of IC1. It can change the frequency by VR1. [...]
