DIY Simple 555 Pulse Generator circuits || NE555 Frequency Adjustable Pulse Square Wave Generator

This is a pulse generator with adjustable duty cycle made with the 555 timer IC. The circuit is an astable multivibrator. A single channel output, the output duty cycle square wave is about fifty percent. Onboard adjustable resistance, resistance can be controlled to adjust the output frequency.
Best choice for yourself or your friend.You will not be disappointed!

This is a very helpful video. Thank you so much.
Using 470μF for the capacitor and 1K for the potentiometer gave me a practical flashing rate.

so its like pulsed dc or literally square ac wave?

[annamull]

Will this handle a more powerfull led? Like a 1 watt led?

[shadymaint]

Would this work to provide a modulating input to a shift regester. I want to build a arcade style controller for my old school NES. I'd like to add an adjustable turbo function.

[roisulfikri]

Out pulse/pin 3, positive or negative voltage?

[zeeahmed]

is it possible to lower the oscillation frequently to 0.5 hz?

[Loudspeaker-ns]

Is not perfect time blinking, if led on 10 millisecond off 20 millisecond 😢😢 please reply how to fix it.😢❤❤

hi i am very impressed by your video. but can u do me a favour, i am making a frequency repellant system that can keeps aways wild animals from our field. by detecting the hearing frequency of the animals, we are planning to make a device that regulates or adjust the frequency of the devices to respond to different animals base on thier detected frequencies. Actuallly waht we have seen in most invented system like they are making a system that geneates specfic frequency so i think you have uses the potentiometer but we are making to adjust automatically. any sujjestion or help you want to give to us.
