Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use ...

In modern homes, apartments, and offices, multiple entrance doors are common. Traditionally, each door requires a separate doorbell, which increases cost and ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

Part of Design and Technology Electronic and microelectronic control systems The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most ...

Applications of commercially available integrated timers, including the NE/SE555, are fairly limited when used in their monostable mode. This is due to their inability to function with all types of ...

We are in a digital era! Now we can add some intelligence to our doors and gates without too much investments. Just assemble this little door timer circuit built around a few cheap and simple ...

If we had a dime for every 555-based noisemaker circuit we see… But this one’s got a twist. [Tristan] does two things that elevate his sawtooth-wave noisemaker above the norm. First, he gets a clean ...
