DELAY ON TIMER ⏲. USING ONLY TWO TRANSISTOR. PROTECT YOUR ELECTRICAL ARE ELECTRONICS EQUIPMENTS.

Hey guys welcome back in this video iam going to showing you how to make a simple Delay ON TIMER ⏲ Circuit. In this circuit I recently fond on circuitspedia site. Thanks for circuitspedia. In this delay on circuit I very very usefull. And this little device use to protect you electrical are electronics equipments. And use this circuit on you speaker protection circuit. Normally speaker protection modules price is little bit higher. But this one is very cheapest and simplest.
Project requirements 👇
1. BC558 TRANSISTOR
2. 2N2222A TRANSISTOR
3.220UF/25V CAPACITOR
4. 5.6 KILO RESISTOR
5. 1 KILO RESISTOR TWO PIECE
6. IN4007 DIODE
7. 100 KILO RESISTOR
8. RED LED
9. RELAY SWITCH

Had to come back and give your video a thumbs up. I never soldered a pcb board before, and after watching this video I bought all the supplies and made 2 of them and they both work as anticipated!!! Thank you soo much!!!

[@RickSunarMAGIC]

It's so easy to follow ,great presentation .u made stuffs easier for us non electrician .

[@romycruz4498]

the presentation of the schematic diagram is excellent.

[@SHIBINSHAN-j3v]

Simple and working,really helped thank you❤

[@robhasselbusch224]

Does a larger capacitor make the delay longer? Good job btw, stright to the point and very informative with all the parts noted

[@lalalazar4639]

Vesy useful . Nice

[@dineshfernando1159]

Hi. It worked perfectly. Thanks for the video. I have some questions. 1)When I’m using this with some battery is this module drain the battery fast?? 2)In my case how can i use this with 10v

[@mohitparikh4455]

Circuit seems to be good but contact resistance of relay will affect speaker output and quantity performance ?

[@ishakmatheni]

Nice!! I am just looking circuit like this.. could you pls able to suggest me to buy the circuit as my expectations as follows? I want to run dc motor repeatedly in particular time interval like dc motor should be running 10 sec and should be not running after 10 sec it should be repeatedly like this....

[@anandtiwary3423]

I want 5 minuts time delay. Will it work perfectly if power has gone for 2 to 3 sec. and come back.i mean again 5 minutes delay. What is the full discharge time of capacitor ?

[@MargaritoMartinezCuervo]

please, explain me why Q1 it emisor is connected to +12 vcd? I think the colector pin should be connected to +12vcd....ok, ok I checked the dt SHETT and this trasistor is PNP, in the schematic link was drawing like npn.

[@hajihaqnawaz3923]

Good

[@Circuitoptimize23]

Thank you sir 😊

[@mdislamuddin5871]

Nice circuits time delay incrise and decrase which resistance value change please replay

[@Circuitoptimize23]

To extend the relay activation time and adjust the delay, simply modify the capacitor without altering any resistors. A higher capacitance value will prolong the on-time delay, while a lower capacitance value will result in a faster relay activation.

[@massoudattarianshandiz5659]

It worked but how can I increase the time to about 5 minutes? May I download the video to watch it at my own pace? I already hit the thumb up :)

[@Circuitoptimize23]

Change the capacitor.. In 5 minutes add 470uf are 1000uf..

[@massoudattarianshandiz5659]

​@@Circuitoptimize23 Thank you

[@everythingispossible9672]

please make .... एक एसा सर्किट बनाओ सर जो लाइट आने पर कुछ समय के लिए ऑन हो जय और कुछ समय बाद बंद हो जाए मैन लाइट के लिए । जैसे लाइट आने पर सायरन चालू हो जाए कुछ समय के लिए

[@Circuitoptimize23]

I don't know your language. Only on English

[@devdaskolekar4037]

Remove background music.

[@xavierr4508]

Nice project, but what an awful schematic! It also has a error on the BC558 PNP bjt transistor: the arrow in the drawings must be backwards!

[@pandag8077]

By. Cuddalur ranjith

[@nairanilkumar6601]

How to increase delay time pls suggest

[@Circuitoptimize23]

Change the capacitor value (1000uf) to increase the delay time...

[@ankurdubey9711]

is background music mandatory ? Music can't go with knowledge videos

[@Circuitoptimize23]

Very very sorry.

[@homwaw7808]

Will this circuit work with two relay switches?

[@Circuitoptimize23]

Yes you can do.

[@sportscricket1775]

Please make a diagram for 220v

[@ronaldfernandes5697]

The 12v connection you showed. But you did not show the output connection to any appliance. Or speaker it was hidden

[@Circuitoptimize23]

I am very very sorry for that mistake. Solution here check out this diagram.photos.app.goo.gl/hgrMFysKQ325NJ5d6 this the relay connection diagram. Follow this step. You will use this circuit on a speaker protection same setp.

[@mechanicdodz]

Sir you have circuit diagram.

[@Circuitoptimize23]

Circuit Diagram available in the video description...

[@mechanicdodz]

Sir one question what is the position to transistor. Because not clear.

[@Circuitoptimize23]

@@mechanicdodzjoin my what's app. I help you

[@jacksparrow4985]

Bro Where is input and output ?

[@Circuitoptimize23]

Mentioned in schematic

[@jacksparrow4985]

????

[@jacksparrow4985]

I'm going to build this

[@sportscricket1775]

can u make this type of circuit for AC 220volt
