Smoothing down the copper traces with a guitar pick. Take this Christmas tree for example, which uses a 555 timer and a CB4017 decade counter in order to drive some blinking LEDs. The ICs are ...

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 ...

If they use an Arduino, it should have been an ATtiny. And of course, if an ATtiny was used, there should have simply been a 555 timer. This time, however, [Tim] decided to actually show how this ...

Hackaday and Digi-Key have partnered on this contest inviting participants to design using the 555 timer chip or one of its variants (556, 558, low power versions, etc.), or even build 555 from ...

Combining the 555 timer and the delay set formed by RC series connection can be made into a monostable flip-flop. Use IN2 as the input terminal of the trigger signal, and K1 to simulate the control ...

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 ...
