6 awesome application of 555-timers in circuits

[@AkashBagFEce]

Sir, it's my one of the favorite ic... Thank you so much for making a this level video on it

[@elewizard]

Glad to hear that. 😃

[@HusainAlBlooshi]

Thanks!

[@elewizard]

Thank you husain as always for your sweet AED100 contribution ❤️❤️❤️

[@marcfruchtman9473]

Thanks for the video. Yea, the 555 timer is a work horse... thanks for the explanation.

[@elewizard]

Yeah, 555-timers are versatile 👍

[@RadioactvPanda]

Thank you! I've always been wondering about 555 timers!

[@elewizard]

Happy to hear that 👍 Keep watching, dude

[@jimsvideos7201]

Thank you as always for the education!

[@elewizard]

My pleasure!

[@elewizard]

Thank you meysam, thank you for supporting me ❤️

[@gilles4444-xu3tc]

Great vidéo and projects. I will use some of them with my students so they discover electronics. + training of english, here in France.

[@jjab99]

Bonne chance

[@elewizard]

Fantastic! Go ahead 😃❤️

[@timokimo8206]

Great

[@elewizard]

Thank you my friend 👍

[@msg1956]

Excellent Video..!

[@elewizard]

Many thanks!❤️❤️❤️

[@perkulant4629]

Great video. 555 timer is so cool.

[@elewizard]

Thank you for the compliment. I agree, 555-timers are eternal👍

[@pierrec1590]

Fun fact: The Volkswagen Rabbit was using a 555 as a missing pulse detector to control the fuel pump.

[@danman32]

FYI there are a few caveats to 555, particularly in monostable mode. The 555 operates by turning off when reaching 2/3 VCC and turn on when drained to 1/3 VCC. So in regular operation the capacitor will be between 1/3 and 2/3 VCC and that's what the timing formulas are based on But at power on, the capacitor is likely at 0v so turn on time will be longer than expected. Also the 555 by itself does not provide reseting trigger. Take a 2s monostable application. The 2s will time out only based on the first time it is triggered. So if you pressed the trigger again 1 second later from the first, it will still turn off 1 second after the second press. Often one wants a delay determin3d after the last press, but a 555 by itself can't do that. You can add a circuit to drain the capacitor from the trigger, thus resetting the countdown but then you might be starting at 0v rather than the normal 1/3vcc standby voltage

[@elewizard]

Thank you for sharing your knowledge with us ❤️😊

[@makeventures]

Very well structured explanations and weaving in the possible 555 timer modes is a very cleaver approach. Thanks for sharing your knowledge.

[@elewizard]

Thank you for watching me 🍻

[@nigelcleaver]

The mono-stable mode of operation is very useful to generate single pulses to feed other circuits a manual 'clock' pulse devoid of switch bounce 'interference'. I use this quite often with a pulse duration of about 300-500 mSec. Shorter durations can be tried, if you're quick at button pressing!. Thanks for all the videos.

[@gerardzi7930]

555 never dead !

[@elewizard]

Yes, I agree 👍

[@christechtime4297]

Thanks! I understand how it is used much better now, rather than just how it is made.

[@elewizard]

Awesome 👍

[@lauriejacobs3980]

Thank you very much. Well presented and most interesting.

[@elewizard]

Glad you enjoyed it!

[@sadunnakipoglu9471]

شكرآ جزيلا على هذا الفيديو المفيد . تحياتي لك من تركيا.

[@elewizard]

Thank you for watching my turk arkadaş

[@jaydeekeejdk3418]

Thanks for the video, excellent presentation

[@elewizard]

Thank you for the compliment ❤️😃

[@t33th4n]

Detailed explanation and math. Truly magnificent work you did here!

[@elewizard]

Glad you liked it and yhank you for being a source of encouragement!

[@sinewaveaddict]

Great video! 555 forever!!

[@elewizard]

Yeah, 555 is awesome 👍

[@SuryaS-rp5ou]

Thank you so much Sir

[@elewizard]

All the best🧡

[@lucsteffens]

Man, you're the best! I love the way you present as well as the project itself.

[@elewizard]

Wow, awesome 😍 Thank you my friend for encouraging me, cheers 🥂

[@elliejackson6907]

Thanks for the nice video. There is another versatile multivibrator chip that is often forgotten. The CD4047. Cheers, EJ

[@elewizard]

Yes, CD4047 is an awesome chip. Thanks for the info!

[@rpontonjr]

I've wanted to do a latching D-pad with LED buttons (to control a multi-camera system for a car). i.e. You push up, up lights up and stays lit. You push any other direction, it lights up instead. You push the center Cancel button or an already lit button, and no buttons are lit. Each lit button also corresponds to an on/off output to indicate which camera is triggered. As a software guy, I was just going to do it with a microcontroller and basic boolean logic. Seems like a fun challenge to do it with a 555 timer instead.

[@freeandfre]

Thank you

[@elewizard]

You're welcome

[@ehsangarosi9215]

Thank you so much for making this video

[@elewizard]

You are so welcome!

[@Dexter-pg9vf]

Thank you mr wizard. Your videos are very enjoyable

[@elewizard]

Thank you for watching me my friend☺️

[@user-mr3mf8lo7y]

Great work. Thanks,.

[@elewizard]

Thanks for watching dude!

[@EricWanyoike-vr8sy]

Thanks for this video . This way you present and explain your ideas is excellent 👏🏼.can you make one about using 555 timer as a clock for controlling other ics such as cd 4017 for different applications

[@elewizard]

Will try👍

[@EricWanyoike-vr8sy]

@@elewizard thankz sir I'll appreciate

[@ellerycadel]

Great video! Thank you.

[@elewizard]

Thank you too for watching 😊

[@UR_VIDEO]

Hi, This is the first video I viewed of yours. Very good educational. I want to just point out that at the end when putting a relay into the circuit, a Back spike diode should be put across the coil to stop the high voltage spike from damaging the electronics. For small relays like you used I just use a 1N4148 small signal diode, cause the spike current is so tiny. Many times you see a 1N4007 which is a standard, but over kill for the circuit. Wish you the best on your channel.

[@elewizard]

Thank you so much for the point you just mentioned 😊

[@martdvn]

Love your videos, keep up the good work!

[@elewizard]

Glad you like them! I will do my best 👍

[@ernieh5664]

Thanks for videos, regards the Garage Door Sensor project, could you tell the value used to generate 38khz on the Tx please.

[@brianp7022]

And dont forget the 7555...low power version 👍

[@tedbastwock3810]

This is extremely useful and interesting video, thank you very much for making and sharing. Regarding the last application, what are some pros and cons of this approach vs. an H-bridge?

[@elewizard]

Thank you so much. Nothing is so special about that circuit, h-bridge is much better in most cases. Here I used that for simplicity. 👍

[@p-niel5328]

Hello good Sir. I really enjoyed your videos and I hope that you won't stop creating enjoyable and informative videos. Since DIY Solar energy system is now a thing, many are trying to make reliable solar charge controllers that are easy to troubleshoot and inexpensive. If you have any idea how to make one using the 555IC, then I would be so thankful to you Sir.

[@elewizard]

Thank you for watching. I will make more surely. By the way, thanks for suggested subject👍

[@mikepanchaud1]

If you look at the internal schematic diagramme of the 555 timer, you will see 3 x 5k resistors in series, hence the name 555!

[@elewizard]

Yes, exactly, thanks for mentioning that 👍

[@tth-coulid]

I used it with speaker and it became so hot.

[@mikejones-vd3fg]

Maybe we should learn the internals so we can make our own 555 timer and not have to pay someones 555 timer salary... just kidding, great stuff (and music).

[@elewizard]

Yeah 🤪

[@stivosaurus]

I agree! This is why I am learning to smelt iron ore so I can build my own car. Three cheers for self-sufficiency!

[@kellyrodgers4961]

One of these days, 3-D printing using metals will be stable enough to where one can print out a durable enough automotive body to use in a ground-up build.

[@cebrith]

Ben Eater shows how to make the 555 out of transistors at the start of his 8- bit computer series.

[@planktonfun1]

pcb is still too expensive for me, the garage door sensor is amazing

[@davidluther3955]

GOOD PRESENTATION,BUT YOU SHOULD EXPLAIN HOW THE INTERNAL CIRCIUTS WORK.

[@mikedub]

There are plenty other videos out there that explain this. He said at the beginning that explaining the IC is out of scope for this video.

[@elewizard]

This video is about the application and real world usages. I think this will help beginners to learn and use the IC. 👍

[@ethiopia-prevails498]

I hear a lot of u-tubers saying 555 can produce 2MHZ, but i couldn't produce more than 600khz. How can i do that?

[@elewizard]

As I remember, it is indicated in the datasheet that this IC can produce up to 1MHz. I recommend referring the datasheet 👍

[@mohsenamiri3772]

سلام.ببخشید شما ایرانی هستید؟

[@elewizard]

Yes 🤪

ببخشید مهندس هر چند برای زبان همه خوبه ولی به نظرم فارسی بگید بهتره
