Using the 555 Timer

[@Dronebotworkshop]

Hi everyone - It's come to my attention that there has been someone masquerading as myself, responding to some comments here with a link to a Telegram chat to win a prize from me. THIS IS A SCAM, I am not holding a contest, nor do I have a Telegram account. PLEASE DO NOT RESPOND TO THESE MESSAGES!! It's happening on a lot of my videos, I'm taking steps to remove them manually, but as I have 162 videos, it will take some time. If you do run across a suspicious comment, I would appreciate you letting me know at [e-mail]. Thanks! Bill (The real one!)

[@feezyadz5940]

Hi sir, thanks a lot for this amazing video. i didn't quite catch the working principle of the latching switch circuit. i am also trying to simulate it but no luck. any more explaination would be great or even the reel. thanks a lot

[@jimdean7335]

Awesome. I sure wish you’d have done this back in 75 when I first learned the 555. I still have a book from back in the day that I refer to from time to time. You have an effective style of teaching, keep up the good work.

[@diggee172]

I totally agree. My sentiments exactly. 🤣. This is great. Young people today are so blessed to have teachers like this, the internet and KZbin. I’m learning so much.

[@alcroc]

Well said Jim, the book just confused the hell out of me. Gonna get me a 555! lol.

I'm teaching my nephew about electronics. So I'm building some very basic circuits with him, to get him familiar with different components and some very basic theory. But a 555 project with some blinking LEDs is what really got him excited about electronics. Everyone should have some 555s in their electronics draw. Such simple yet versatile little components. This video came in really handy on reminding me of how to use the chip. Great explanation!

[@MrSevenEleven]

Just don't believe everything he says. There's lots of wrong/misleading info in this video, and I'm only 6 minutes in. 😬

This is a REAL tutorial, none of that 12 mins joke, thank u!

[@thfreakinacage]

Whenever I search for a topic on KZbin, I'm always happy to see that DroneBot has covered it because then I know I'll learn everything I need to know in a thoroughly, but simply, explained way ❤

I’m an older dood that was surrounded by electronics growing up, but never cared about any of it until recently. I grabbed an off-market Arduino kit and began collecting and disassembling all sorts of machines to try and teach myself. These videos are great for helping me wrap my mind around this stuff. Thank you.

Super Helpful Video!!!! Now, I understand Physics without attending School 😇😇😇

[@KJ6EAD]

The 555 and 556 have 2-transistor totem pole outputs. In the 4017 sequencer circuit there's no need for 10 current limiting resistors for the LEDs. Since only one output is high at a time, a single resistor on the ground side of the LEDs can be shared.

[@Theineluctable_SOME_CANT]

And..... The 4017 will current limit (run out of drive), so the resistor really is moot.

[@KJ6EAD]

@@Theineluctable_SOME_CANT I've only been able to get about 15mA out of the 4017 but can't recall finding a clear specification in the data sheet. It often makes good sense to use drive transistors.

Thank you! Like the 50 caliber machine gun, it’s a classic and still in use years later. Although there are others that could be use, it’s reliability seem exceptional. I’ve always wanted to learn more, and I know breadboards are the best way to learn circuitry. Knowing about the 555 makes it even easier (financially) to acquire it.

This is a general comment so, not necessarily about this video. I just want to say I like your channel a lot because all your explanations are crystal clear and your visual animations are always top notch. There are several good channels out there talking about similar topics but yours is amongst the best. Don't take offense but the only thing I dislike about your channel is the fact that you talk very slowly...! : so I end up watching all your videos at 1.5 times normal speed, and I find that the flow of your speech is just about normal then lol... : ) So... Kudos and keep up the good work !

Excellent video. I no longer have the project or the schematic, but back before cell phones I put together a circuit using a 555 timer in order to patch my mobile CB radio to my home telephone. I was able to do this only when touch tone phones were in use. I only had one-way communication, but it worked well, even got about 10 miles from my base antenna, which was mounted in the top of a pine tree.

Many automotive applications for the 555 chip. Back in 1970’s I came a cross a great application from one of the electronics magazines of the day. Allowed me to fit adjustable intermittent wipers to my 1960’s Morris minor. What was great about it was the on/off switch was an adjustable pot. So unlike even modern intermittent wipers I could vary the timing to suit the rainfall. Rebuilding an old 1970’s Landrover currently and plan to incorporate this in the build.

Hi Bill, sometimes it's nice to 'step outside' the microcontroller world and get back to basics. The 555 has always been a most useful device. It would be good to see more videos along this line (and perhaps some hybrid micro/logic chip outings).

Thanks for your extremely clear lectures. On it being a rumor that the 555 was chosen because of the three 5k resistors, I think it's still possible to turn out true even if it was chosen by someone in the marketing department who thought the name sounded cool. I mean, if I knew nothing about electronics at all and someone showed me a schematic of a new timing chip product and told me market it, the three 5's would probably be the only part I would immediately understand and, hence, find "cool".

[@t1d100]

Thank you, for another wonderful video! Your point about the price advantage of the 555 verses micro-controllers is well taken and not disputed, at all. But, I would like to share some knowledge, for the folks that don't know much about MCUs. There are many small micro-controllers that fall within your $1 total project budget... The ATtiny85, PIC12F683, etc. 1) They offer different functions than a 555 and those different "muscles" may be advantageous to the project's goals, so they are worth considering. 2) These are older MCUs and they are being phased out by the OEMs, in favor of their newer designs. I know all the business reasons for phasing out a product, but losing these little powerhouses is a pet peeve of mine. If we will continue to buy them, they will surely continue to make them.
