Thanks very much for this. As a complete newcomer to Arduino I have been able to write and edit my first simple sketch and actually understand what all the commands mean. Well done for such a well-planned tutorial.

Very good video. I showed this video to my class and instantly they became newton.

[misamiamya]

thank you for the code explanation! very helpful!

[NezukoKamado-ruuc]

Tysm! this helped me a lot when I was required to do this project <3

[manupriya]

bro i am totally fresher to this concept in my clg they are giving placement training regarding IOT, but i could not understand anything today after seeing ur vd i felt happy thank u so much pls continue do more vds

[hansikawijerathne]

Thank you very much💗 this is very important👍

[nisarggaming]

sir in my case there is some error in uploding infact I use same code and do all as you done but my port shows two port com1& com3 .I chose both but both led to error

[sumalatha]

Sir I have installed arduino in Ubuntu 20.04 my port is like /dev/ttyS4
My output is showing like programmer is not responding.
One more doubt as u said use digital pin for led connection if I connect 7 and running example blink program it's blinking. But when Iam using pin 4 led is not blinking

Hello Sir, could you please provide me with the purchasing link for Arduino Uno from Amazon that you used in the tutorial? The link mentioned in the tutorial description is not opening.

great video bro I am from software background but i always have a question about these things that how it work now i understood

[werideclub]

(very new to Arduino)Starting from my requirement
I need to turn on a water motor(5v) for about 2 mins after every 12 hours, basically trying to automate water pump for home garden pots when I am travelling.
I feel above code will perfectly work just I need to tweak delay time, is there anything else I should consider ? any other way to do it?
also can I use Arduino Nano instead of UNO? or Uno is better?(as I said new to this)

[usmanbeacon]

How can i give input from pc to Arduino for led on or off by command line?? Or any other method??

[ahmedal-kharusi]

Hello nice video, why you didnt do a resistor for the led so it will not burn with 5v ?

[DTalesJourney]

Sir mujhe har 30 seconds ke bad blinking led chahiye 5 seconds le liye...
Plzzz help me with the code

[EdTechPraveen]

Bro my transmission light blinking automatically please help me

[aryanraj-brnp]

Sir we know that an LED will fuse if we use 5v dc. Here in the code we are not setting up the voltage to 3.5v approx. which is normal voltage for led. So how the Arduino automatically giving correct voltage for led. Plz tell.

Hi mate. thank you for this video and your hard work, it is a very good video adding extra information for us. thank you very much. :¬)

Can You provide me Report of this program...🙏

[poojasureka]

Why have you connected led 1 to 7 can it be connected to any other number in the digital section

[RAMKUMAR-ebkq]

what is the wire name connected from aurdino to the system
