EL TIMER 555Este excepcional Circuito Integrado muy difundido en nuestros días nació hace 30 años y continúa utilizándose actualmente, veamos una muy breve reseña histórica de este C. I. . Jack Kilby ingeniero de Texas Instrument en el año de 1950 se las ingenió para darle vida al primer circuito integrado, una compuerta lógica, desde entonces y.......

In this article we learn how to make a multilevel (5 level) cascaded inverter circuit using a very simple concept developed by me. Let's learn more regarding the details. In this website so far I have developed, designed and introduced many sine wave inverter circuits using straightforward concepts and ordinary components such as IC 555, which happen to be more result oriented instead of being complex and full of theoretical jumbles. I have explained how simply a high power audio amplifier can b.......

I really liked this project. Combining two 555 timer chips really helped cement how this little chip works. I had forgotten much about the pins and how the 555 functioned, so wiring up this circuit was very helpful. I highly recommend that as you wire up each 555 timer chip, you examine carefully the wires that connect to each pin and try to understand exactly what is happening at each pin. You'll probably find as I d.......

This circuit can be used to activate a relay for two or three minutes. Pressing the switch the relay will be activated. Changing the 1M resistor with a variable resistor you can vary the time. The 0.01 capacitor is important because it prevents any false triggering. The circuit will work OK with 6 Volts without any modification. If you want to use 9 or 12 Volts, you need to change the relay with a 9V or 12V relay. Using this circuit with 120 VAC is not recommended, however, using the right parts.......
