In this project we are going to design aSimple Time Delay Circuit Using 555 Timer IC. This circuit consists of 2 switches one for start the delay time and other for reset. It also has apotentiometer to adjust the time delay, where you can increase of decrease the time delay by just rot...
The circuit is set to run at a frequency of 3 Hz with a duty cycle of 50%. The operating frequency of this 555 strobe light circuit was determined with the help of a handy 1 uF capacitor C2 connected between pin6/2 and ground of the 555 timer/oscillator. The 555 output (pin 3) is...
A square wave oscillator using 555 IC can be configured to give symmetric oscillation (50% duty cycle). Other circuit uses diodes to split the charging and the discharging paths through different resistors, but here we need no such diodes. Here is the schematic diagram: The time period for t...
This LED flasher give similar circuit with the previoustransistor LED flasher, but this circuit use a 555 integrated circuit chip as the active component. Here is the schematic diagram of the LED flasher circuit: This circuit gives alternating LED flashing, but with different flashing period between...
This simple IC 555 timer tester not only tests IC 555 in all of its basic configurations but also tests the functionality of each pin of the timer...
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...
