A team of the National Investigation Agency (NIA) on Thursday launched an investigation into the looting of explosives ...

The ambulance was locked at the time while the paramedics were inside a patient’s home in Harrow, north-west London.

So I was pleased when I learned about the recent creation of the US $35 Three Fives Discrete 555 Timer Kit, sold by Evil Mad Scientist, a DIY and open-source hardware company located in Silicon Valley ...

This non-conventional experiment gives a scope to learn the internal structure of IC 555 to know how the current flows inside the IC. In contrast to Experiment 13(A), where the internal passive ...

Motor speed controller using 555 timer ic in astable multivibrator mode to produce the PWM pulses necessary for control over the speed of the motor. A 555 timer ic, operating in astable multivibrator ...

So, I’ll add my reason to the list: the wide use of the 555 timer IC. “What’s that?” you’d ask. “How’s that possible?” I’ll tell you how. This IC has been on the market and in wide use since it was ...

Connect the resistor R1 and the capacitor C1 in series between Vcc and GND, and the point of the resistor-capacitor connection is connected to the collector of the transistor inside IN1 and 555. The ...

Abstract: The 555 timer IC is a well-known integrated circuit having been widely used as a pulse generator. We propose a circuit containing a single 555 IC, an LED, an inductor, two capacitors, and ...
