Latching Touch Sensitive Alarm Circuit on breadboard | 555 Timer project #2

[@ElectronicswithReyon-yp2dy]

Most circuit videos not explaining theory. But you explanied that brilliently. I learn a lot from you. Thanks a lot. Keep it up the good work.

[@robitops1547]

Practical with theory + Animation. Awesome job

[@haroonraseeth4457]

Mini project without arduino video Podunga please 😭😭

[@UsualYaddaYadda]

Thanks. Very intuitively explained. Great visuals and no nonsense talkthrough.

[@NawaalRahmanKazi]

The circuit was working earlier, but I had to put in the transistor backwards for it (collector connected where the emitter is meant to be, and vice versa). However, now it is working but the circuit activated immediately after connecting the battery, and the pushbutton is resetting the circuit is expected. Touching the wire seems to do nothing, unlike earlier. I have already checked the circuit several times and switched the transistor back and forth. I did not change anything, it was simply stored in a drawer in my room. The LEDs stop working quickly, and I’ve had to replace it many times (I’m using the correct value for the resistor connected to LED).

[@NawaalRahmanKazi]

Is it possible to use a resistor that has a value of 390 Ohms or greater for a green LED (when giving 9 volts of supply)?

[@newworld5733]

Awesome Boss, keep it up, that's how engineers are different from others. Thanks a lot

[@lcpthr6861]

Hi

[@lcpthr6861]

This circuit, which act as monostable multivibrator or astable multivibrator or schmitt trigger ? Tell me bro 🙂

[@siamakaghazeinali]

Is there a way if the theft using gloves it be such sensitive to detect touch? The body has electromagnetic field.

[@hssabir3340]

Great explanation. I made it. But buzzer is working only if resister and open cable together. Please help me

[@viveksharma7675]

I need to make it less sensitive. Buzzer should be work only when the wire touched. Is it possible?

[@aungmyokhaing6795]

How to build 3pin IR receiver instead of touch in these same function or circuit? Please explain.

[@GeorgeJFW]

Well done!

[@bhavanireddy7248]

I tried it &got output tqsm sir for explaining it very clearly.. Sir please provide report for the above touch alarm circuit

[@electronicshelpcare]

Super idea.

[@mysticaldimples4345]

Can we use a puedo electric sensor in it

[@ShravanKumar-di7ii]

Can we use this to sense water

[@GreatIndianCreator07]

Sir i want to close it after some delay please tell how to do that that it auto turn off after 3 sec

[@vaibhavnagare8549]

Nice bro keep posting videos love you bro

[@Abu_Hamza_Al_Qassami]

How i make the PCB design of that project

[@suswethamangena6539]

Sir, can u pls tell me the value for led series resistor?

[@biggeorge3826]

Mine not working I used a pcb can someone explain to me what could be the problem

[@prateekmahajan190]

The explanation is great, please make some projects with Arduino or esp8266

[@elonics]

Thanks. If everything works as planned, I'll start making projects on Arduino from the beginning of next month.

[@prateekmahajan190]

Elonics - Electronics Projects on Breadboard That's awesome, thank you bro. Keep up the good work.🙏

[@praveensagar3529]

Why no videos after this

[@lcpthr6861]

Which principal are used here monostable multivibrator ,astable multivibrator or schmitt tiger.. Tell me bro

[@Fluffypotatoes4]

How can I make this only start when you stop touching it?

[@harshitsaxena5602]

Great work bro keep doing

[@mdsharook894]

it works 2 3 times but after that Keep buzzering after reset button what can i do

[@xavierkang2974]

How do u connect the same button but with 2 legs only? Pls help

[@VijaySingh-eb6yz]

Hi Can you tell that how we can make a secured atm with sound and touch sensor

[@VijaySingh-eb6yz]

If yes you can message or leave it

[@electronic7979]

Very good 👍

[@Rawshorts1]

Sir how to give the power supply?

[@sherrysaeed5378]

Who many range this circuit

[@KBtek]

I wanna make 2 meter proximity sensor can you please help me.... Thanks

[@aishwaryaravikumar6049]

Nice work.... I want 2 use this circuit to turn on wn supply is given and then reset with button. How can i do this??

[@phonemyinthein9832]

Hi...It only works when i touch the negative supply and pin 2 at the same time or.....connect pin two to negative supply.

[@lcpthr6861]

Same

[@lcpthr6861]

What will do

[@sakshamsharmagsec4529]

this circuit is not working on tinkercad please help....

[@naderhumood]

V nice .....Many thanks Sir........it's great.

[@pruthvimaghudiya2485]

What is the value of R1 and R2?

[@hamzanadeem8469]

Bro is ma AP na Resistance kit na OHMs ki use ki ha bro tell me please as soon as possible

[@SachinSingh-cl9nq]

Sir i want to use LDR in this circuit instead of touch wire what i have to do

[@elonics]

That'll be a totally different circuit. You can try modifying this circuit: kzbin.info/www/bejne/qJnchKlumrWqr68

[@i.mpossible]

Continue sond is on... Any solution?

[@knowthrvdo]

make one video on break failure circuit It is also a great topic for a mini project and on KZbin their is no video is available in the way you explain projects

[@vuka9484]

Can you give me a flowchart of this circuit algorithm?

[@dhrubajyotisarkar5394]

Sir... In my case, it works when I touch the negative supply wire... What's the reason...?

[@hgameryt6151]

YES SAME HAPPEND TO ME ALSO WHEN I TOUCH BOTH THE TRIGGER INPUT AND NEGATIVE TRAIL IT WORKS OR ELSE IT DOESNT ,WHAT MAY BE THE REASON DUDEE DO U KNOW ???

[@sakshikadam1417]

Sir, how to make the electronic music cup.

[@elonics]

You can directly purchase it. Ask for a "Buzzer" or "Piezo-Buzzer"

[@santiagomaciasvillegas2186]

Eres genial amigo le mando un abrazo desde San Jerónimo Antioquia Colombia grácias

[@elonics]

muchas gracias

[@jeymarnagac1640]

What is the value of first resistor did you put??

[@elonics]

You mean the resistor used for the LED? It's 220R

[@DevidasBhobe]

The pin 2 is left floating unless touched which does not seem like a good idea

[@bhanusampath6500]

Can I produce sound frequency of 25,000 hz using this same circuit

[@elonics]

You should use another 555 timer IC in astable mode to generate the required frequency

[@bhanusampath6500]

Can you please help in making dog repellent system which is my project Target is to produce 20,000+ hz sound frequency

[@manvisharma1173]

Alright I made the circuit but it won't shut up and isn't obviously touch sensitive what now

[@mayanksrivastava2302]

Sir my led goes off only on holding the switch and gets on when on when I release it and buzzer constantly beeps. Plz help

[@elonics]

Try using a DC power source from batteries if you are currently powering the circuit from a AC-DC adapter. Next try removing the push button switch and manually apply +ve voltage at Pin-6. If it works now, the switch connections might be incorrect. Also the circuit is sensitive to AC sources if they are very near.

@@elonics why it doesnt work when using ac dc adapter? Mine has same problem too. How to have the circuit results with ac dc adapter.

Is there a circuit diagram and explanation for this video?

[@elonics]

It's in the video. I didn't create the project page yet

As per the circuit shown the push button causes a short which does not seem like a good design

[@sreejachandran1525]

Super

[@electroniquepassion]

Thank

[@chanchalsharma2479]

sir in my citcuit it works by sensing object ,when i come to near it then it works without touching but how is this possible

[@elonics]

Because of induced electrostatic charge. It works similar to how two plates accumulate charges of opposite polarity in a capacitor

[@aayushbanerjee1463]

He says to connect pin 4 to negative rail but connects the 8 th pin to the negative rail...

[@elonics]

Both the Pins 4 & 8 are connected to each other. So connecting either of the pins to negative rail will do

I guess you are in India. You talk too fast for you to use English. Maybe stick with Indian. We English speakers don’t talk “a mile a minute”. Especially with technical topics.
