LED Heart Beating Effect

[@gerardoramireztorres7871]

It's amazing what you do, this channel deserves much more recognition.

[@yousefLa52.]

Why you don’t put a schematic of the circuit????

Description

[@BurningBureacracy]

The diagram in the description is only for 11Leds but the one shown has about 24Leds Not sure if that changes it up too much but I can see why some who are new would be confused on how to alter things.

[@jlucasound]

Just in time for St. Valentines Day!! Genius!! ❤ 😍 😂

[@guitar5044]

Based on your schematic I did a simulation with your component values and it is not working. The voltage commutates between 2.53 V and 2.6V. It also does not work on a breadboard. The LED´s have a constant brightness. Does your build differ from the schematic? I´d be very thankful for a hint.

[@tanish7301]

Please help me too

[@Electronzap]

That's a nice way to use fading LEDs.

[@DealEyeFF]

Sir BD 139 transistor se hoga ya nahi 😢.... please reply 🥹🥹🥹

[@zoksss5323]

How long will battery last? 2200mAh/(25*20mA) = 4.4h of runtime. Is this correct math?

[@celilb6675]

Hello sir, i have been trying to solve a problem for 2 hours please help. I made the connections just like you, I gave power from the power supply, but once on, it goes out slowly. What is the reason for not looping?

[@estechknowledge]

Do you use the circuit diagram to make this project?

[@patomahony9747]

Nice video. Perfect for a project I have in mind. Just wish I could scale it down in size to run from and be around same size as a cr2032

[@ASAPCROSS]

That's Awesome Shout Out From México

[@ilyapetri4enko106]

Shouldn't you put resistors in front of the diodes so that they work longer?

[@mayankkukreja1013]

Hey Bro can you make another video showing how you did the connection because when i made the same thing it didn't worked and rather led just stayed on all the time so can you please show in new video that how you made the connections

[@estechknowledge]

You can find a circuit diagram for this circuit in the video description.

You are a great Mentor 👍🏻

[@ioanahulea1335]

Where could i place a button , up after the transistor between him and the first led (i am looking at the schematic ) ?

[@ioanahulea1335]

And which of the 120 k i should replace with 220 k ?

Very nice. Thank you for making & posting this video. God[Bible] Bless.

You don't need to change any components for 9V supply.

[@sr.G-GeovanniMR]

Está muy lindo e interesante el proyecto me encantó en verdad, pero tengo la siguiente pregunta. Se puede hacer también que tenga sensor de detección de ruido? A qué me refiero con ello que con un aplauso ó música los LEDS prendan rítmicamente. Se puede hacer algo así? Saludos desde México. 👍🏻😍✌🏻😃🇲🇽

[@mackymuhaemin]

R3 = 220k not 120k that is true ?

Este circuito puede funcionar con 5 volts en vez de 4 volts?

[@estechknowledge]

Yes

[@adzeta8719]

If I want to increase or decrease the speed, how do I do it?

[@estechknowledge]

Attach a potentiometer with the 10k resistor, that is connected with pin 7 and 6 of the 555 ic.

[@adzeta8719]

@@estechknowledge I am a beginner in electronics, there are 3 legs on the potentiometer, which I connect

[@MrDurham55]

@@adzeta8719 Use the top (this connects to centre), and either one of the lower two. Have a play with your multi meter, set to resistance and turn the pot back and forth.

@@davedave6010 no puedes hacer que suba, pero si bajar. Usa resistencias

[@codyhanthorn4270]

Add a T/on delay and another circuit for both chambers of heart.

[@jlucasound]

So, no BMS? I am sure this would run 24/7 for 6 months. It would pay for itself even if the battery went totally flat. I guess one could just monitor the voltage and charge when necessary. I would! I suppose most here would also. OK. I Love it. ❤😄

[@zoksss5323]

Correct me if I'm wrong, but the battery is 2200mAh, and 25 diodes in parallel draw 20mA each, which is 500mA, which means, 2200mAh/500mA = 4.4h of runtime?
