Thecircuit diagram of the Schmitt trigger using IC555is shown below. The following circuit can be built with basicelectronic components, butIC555is an essential component in this circuit. Both pins of the IC such as pin-4 & pin-8 are connected with the Vcc supply. The two pins like 2 &...
The 555 timer IC was introduced in the year 1970 by Signetic Corporation and gave the nameSE/NE 555 timer. It is basically a monolithic timing circuit that produces accurate and highly stable time delays or oscillation. When compared to the applications of an op-amp in the same areas, the...

Time Delay Relay Circuit with 555 IC A time delay relay is one type of switch that operates between two terminals electrically like NC (normally closed) and NO (normally open) which mainly depends on activating & deactivating the coil within the relay. There are some relays where the switching...
Pulse Amplitude Modulation Circuit using 555IC The frequency of this must be a minimum double to the audio signal. Generally, it is 8 KHz as the audio signal is equal to 3.4 KHz however for enhanced quality this circuit uses 32 KHz. The output of the pulse train can be given to the ba...
