I had heard some stories in the past concerning how poorly the 555 ran below Vcc = 5V, so I embarked on an endeavor to see if I could improve operation. The spec sheet specifies minimum Vcc at 4.5V ...

“We need a circuit that generates a UV LED light pulse for a couple of seconds over about a 30-second period,” said the manufacturer of a portable aftermarket product with a florescence element. The ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

Simply adding a diode and potentiometer to a 555 timer operating in the asynchronous mode yields a pulsewidth modulator (PWM) with a duty factor adjustable from 1% to 99% (Fig. 1). Applications would ...

Over the years, readers have often commented that microcontrollers (or more specifically, the Arduino) are overkill for many of the projects they get used in. The admonition that the creator “Should ...

It’s back! The 555 timer contest wants to see you do something cool with the 555 timer chip. At stake is the adulation of electronics geeks everywhere. Three top winners will be awarded a $150 ...
