Electronics is in everything from our phones to our electric toothbrush so it is important to understand how they work. by making small scale projects you get a sense for electronics so I set up this channel so I could share my enthusiasm in hobby electronics. I hope to encourage people to start the hobby and to show them the rewards of making something that works.
Transistor Night Light Circuit
In this video I will show you how to make a circuit that turns on an led in dark conditions or light conditions using a transistor. You will probably need to pause this video along the way to be able to follow.

555 Laser Tripwire
Просмотров 2,1 тыс.10 лет назад
555 laser tripwire- this project uses a transistor night light circuit to trigger the 555 monostable circuit when which then triggers the 555 astable turning the led and piezo bleeper on for a few seconds. I have placed a cheap laser pointer directly onto the led and whenever the beam is broken it then triggers the monostable circuit and then the astable circuit. Please like, comment and subscr...
LED Traffic Light Control Circuit
Просмотров 2,5 тыс.10 лет назад
Traffic light circuit - This would be a great addition to any model railway layout. This project operates red, amber and green LEDs in the sequence for a traffic light. The 555 astable circuit provides clock pulses for the 4017 counter which has ten outputs. Each output becomes high in turn as the clock pulses are received. Appropriate outputs are combined with diodes to supply the amber and gr...
How to Ballast Track

How to ballast model railway track - This is a quick tutorial on how to ballast model railway track. Basically you sprinkle some out and then smooth it down and then glue it its that simple! Obviously there's a bit more to it like spraying it with water and adding the grass but I will hopefully cover everything in the video! I use woodland scenics medium grey ballast. Please don't forget to lik...
Random Led Flasher
Просмотров 45 тыс.11 лет назад
Random led flasher tutorial - This project flashes eight LEDs in an apparently random manner. It uses a 4026 combined counter and display driver IC which is designed for driving 7-segment LED displays. The sequence is not really random because seven of the LEDs would normally be the display segments, the eighth LED is driven by an output that is normally used for driving further counters. This ...
Arduino HC-SR04 Tutorial

Arduino HC-SR04 ultrasonic rangefinder tutorial - This project uses an arduino and a SR04 ultrasonic module to switch between two leds when an object comes in range with the SR04 the led switches from green to red. You can extend the project by simply adding a bleeper by putting the negative side to ground (no resistor needed) and the positive side to the same row on the breadboard as the red l...
555 bistable
Просмотров 18 тыс.11 лет назад
555 bistable tutorial- A Bistable Mode has two stable states, high and low. Making the Trigger input low (pressing the button) makes the output of the circuit go into the high state turning the led on. And by making the Reset input low (pressing the other button) makes the output of the circuit go into the low state turning the led off. type of circuit can be used to make a model railway signal...
555 Monostable Tutorial
Просмотров 188 тыс.11 лет назад
555 monostable tutorial- A Monostable Circuit produces one pulse of a set length in response to a trigger input (pressing the push button). The output of the circuit stays in the low state until there is a trigger input, hence the name "monostable" meaning "one stable state". This type of circuit is ideal for use in a "push to operate" system for a model displayed at exhibitions. A visitor can ...

8x4 dcc model railway layout
Просмотров 7 тыс.11 лет назад
I have just started the hobby of model railway and thought I would do a video of my oo gauge 8x4 dcc layout. As you can see it is still in the early stages but in a few months it should be further developed. More model railway videos to come! In this video you can see a Hornby regional railways class 37 and the hornby little giant. Please like,comment and subscribe.

PLEASE LIKE AND SUBSCRIBE In this video I will show you how to make a simple led flasher. The led flasher is usually the first circuit for a electronics hobbyist!
Alternating led flasher with 555 ic
Просмотров 242 тыс.11 лет назад
Dual alternate led flasher using 555 timer chip This circuit uses the 555's astable operating mode meaning that the circuit has no stable state hence 'astable'. The output continually switches state between hight and low.
thank you brother, he liked it very much
La zizic me tue.
PLZ i want the code , the link is not available
LEDs are both on but not flashing. Why?
skip the annoying sound!
SBK
Cyrus Wilson, this was a great circuit to build easy to understand and l learn how make these Led's finally random flashers. Thank youi
Mine lights up but doesn't flash, why is this so.
Would you please upload circuit diagram
THIS IS A 'WATCH ME' VIDEO - NOT A TUTORIAL BY ANY STRETCH!
excellent..i was looking for this for a long time.finally i got it.thanks a lot.
just the music I wanted to hear
Manque potentiomètre ajustable
Better color coding for wire would be better
thank you
thank you
How can I make the red and blue led blink the same amount of time, when you changed the resistor that connects pin 7 and 8 you can see how the blue led stays on longer than the red does
thank you mate finally I did it
Best ever surcuit.I tried other veideoes but it did not work your video is real and understanding √√√...thanks.
Why show this if you’re not going to show the build?
Thank you. You helped me out of a pickle. My breadboard was naf. Tossed it and soldered circuit spider fashion. Worked first time. Many thanks.
Best monostable tutorial ruclips.net/video/1PFKwud-TKI/видео.html
"Thank GOD", and thank you 😉 Is it possible to get a copy of the notes and schematic of this circuit 🤔 I'd like to build and experiment with this circuit myself 😐 Let me know 😎🙏🏾😎
Thanks bro. Now I understand it properly
Blessings, i almost gave up. I have 50, ne555p ic's. I have been trying to get anything to work. Tried just about all the tutorials on youtube. The road has been long and tiresome. Today i drove to another state to aquire 4 different brand 555 ic's only to get there and be told that only 2 were available. And to make matters worse they were not even true 555 ic's but nte955m. I was told that they are just as good. I bought them reluctantly and drove home. Tired the first tutorial from yourtube l and nothing... came across this tutorial and book. The lights blinked..😲. They are blinking fast and i increase the capacitor and still blinking fast. Im happy that i atleast got it this far. Thank u again!
Why does my led gets too hot
Thankyou ...useful... One...
Circuit diagram please
I need circuit diagram of this bro please
Thanks man
Hi Protronics99, how can i transfer this breadboard project onto a proper Stripboard, i know how to solder & wire etc, any tips/help is/will be greatly appreciated....Steve
Would I appreciate it if you showed us the scheme of the installation?
y el pin 5 queda al aire
One led is blinking and the other is not blinking what is the reason
My light is on, then when I hit the switch it turns off for a certain amount of time, lol. What the hell am I doing wrong?
He shows that happening in the video
@@jonh.5317 hey man..sorry. this was so long ago I can't even remember doing this...lol.. I do remember getting all three 555 times functions working but... I just dont remember that particular problem.
mbae pio la oikopaa kp ndorekoi ko nde video la esquema ha pea kausa ndoikoi che proyecto hendy hina la situ kp!!!!!!!!! mojoli ndoperdonai oree >:d XD
Replace the 100uf capacitor with 10uf. Thank me later. It's the popo.
yea it blinks faster. try 1uf.
Tanks my partners
Thanks! It works, make sure capacitor is more than 100 uF
is there a circuit diagram for this?
Not working
Pa hug naman po sa aking channel kuya done na po ako😇
How big is the access whole in the middle? The layout looks good.
thanks you so much😙
U use 9 volt battery?
thanks simple ,works
Nice work
Great job Sir. ....Thanks very much indeed 👍
Tried 20 times, and doesn't work for me !
Great job Sir Appreciated..........👍
Random? Nice try, but I can clearly see a pattern right there.
Right me too... Cant find anyting to achive random flashes looking similar as ligtning...
