when i plug it the sensore got very hot it almost burned if i didn't unplug it even when i use 3.3 voltage

Great video but please cut your nails

You only need one 100 ohm resistor rather than 10 as only one LED is on at a time. You connect all the cathodes together and then connect a 100 ohm resistor from the common cathodes to the negative supply rail.

Please can you explain the working of this circuit

My sensor beacomes too hot and shows value more than 200 in the output. Can you help me with this ?

Send me the code bro please

What is the name of IC used for '5V'?

#SDevElectronics Sir can you please help me that when I uploaded this ir sensor code and open serial monitor automatic hex code is simultaneously displaying but I didn't press any remote button, why it is showing please help me please 🥺.

if all the buttons pressed in the same time it will unlock. right? isnt that is an issue

Can i use more ir pair instead of 1 ir pair so circuit is working or not ?

This looks quite simple unlike others.

DIAGRAM FIGR BRA KREN SIR

Hello there. Your video is very informative. I have a question. Is there a way to code an alert in difference of temperature change, for example, when the temperature increases or decreases within 5 degrees?

Ye board mil sakta hai kya

Thank you so much! I thought I was never going to figure it out!

Nice

great

coding videos which blast music need to be downvoted. ridiculous. If you're not going to say anything, we don't need a video.

My board is having 4 diode. Can I connect directly to the transformer.

Which IC is used ? Other than 555?

What is the first you put in pcb before 10k resistor ? Pls reply

Give me a circuit diagram to install the 7474

How to upload a code ? .. Can i use this DIY Arduino to my project for Servo motor Toll gate ?

Could you give the diagram of this circuit?

Fake

Bro mine not working and I made it twice .iam using 50k variable what should u change

How do i alter it to make it detect black instead of

nice video sir how to make duel timer

awesome

Bro i need help. My mini lcd has stopped working. How can i contact you.

Audio output connection?

Hi .can we use the DHT11 temperature and humidity module as a substitute to the lmd35 ic?if yes does the wiring the same

sir i have have a problem my value decreases when i rise the temperature near lm35 ...what should i do in code kindly tell this.

Etni jaldi keya he jahaj akrna he keya

can we add a button to it that each time i have to press the button to generate another number?

Circuit diagram

I am using a potentiometer to control and slow down the speed of the 555 and the LM4017 outputs. I'm wanting the LED's to fade when they come on and off and I am experienced with many different circuits that fade LED's. I have tried basic cap and resistor pairings at the LED's and also by using the 4017 outputs to drive bc547's transistors that turn on the LED's, again with different arrangements of caps and resistors on the base and/or emitter sides and I've also tried resistor/cap arrangements that can turn square waves triangle or sine, with and without the transistors. In all cases, I can get a very controllable fade out of the LED's but cannot get them to fade on. Is there something about the output of an LM4017 that will not allow it's waveform to change or for a capacitor to slowly charge? Or something else that I just can't figure out?

Thank you so much

Can l use 12led

Hey, can I use 10k or 220 resistor instead of 100k ? I just dont have 100k resistor

Gutes Video, ich verwende 2 Sensoren für einen Bahnübergang auf der Modelleisenbahn Spur z

Circuit diagram pls

Bro jo left to right wala program h one by one jb led on hoti h or wahi on hoker ye program kaise banye

Hi... I want to design a door locking system with 4 sequence RFID cards using Arduino and em 18 module... Can you help me

Variable resistor lagaya he vo circuit me draw nahi kiya

When I powered my arduino with a 9v external power supply adapter, the reading temperature every sec is not stable, it fluctuates from 32, to 19, to 22, to 27 so on.. please help
