Can someone help me to figure out how to build own nanoleafs? I want to detect with a esp32 automatic how much own panels are connected and set individual colors and animations. But how can it set automatically number up the IDs for every panels? Every panel should have 18 rgbw LEDs. I don't know which LEDs I have to choose.
can u explain y we using 4.7kohm particularly rather than other values.and hw can we calculate the value and alsowhy they design like the open collector whats the purpose.please reply.
not 4.7 k exactly you can use upto 10k to protect pin with external resistance from high current driven to . this concept for working with pins with high accuracy and without lossing information.
No you cannot use 10k resistor you have to use 4.7k becoz the board which you are using may have 5v input and current drawn by that board will be 1A so according to ohms law R=V/I so based on that they will decide that resistor but according formula it has to be 5k but why they kept 4.7k becoz you board was actually designed for 1A current but it was drawing only 700mA so that's y they kept 4.7k go quick calculate R=V/I 😃😃 and that not normal resistor it is called pull up resistor actually it will be connected either to vcc or ground only if you have any doubts just call me 9108962754 I'm an embedded programer and hardware design in embedded so I can clear your doubts easily
Sir, please tell me the is it a serial communication or parallel?? which protocol will do parallel communication? which communication will be used to communicate faster? either serial or parallel.
With out theoretical you cant work on practical , we must clear with registers what we are using in i2c protocal , and Thier responsibilities , then you can start study with practical
mohammed shahid i know theoretical aspect is important but practical vision is more prominence approach...if he is in theory dialogue y they don't jump into practicalities
@@sahibalam401 it's for beginners , not for experienced persons who have knowledge on ARM...if you really wants any practical knowledge join any institutions or subscribe any channel for money..now a days for theoretical only channels costing and practical means heavy bro, I suggest you to work on 8051 in practical , if know already means , it's no problem download data sheets of ARM and study each register and implement code on software , it's same like 8051 only , but registers will different for analyse takes more time
The best video and superb explanation which is generally not found in the books.
I want information about spi protocol also.
Your teaching is superb.
really informative, good explanation & basics covered.
Extra ordinary, could you please create a video for spi

very nice video thanks
Great job...
Good explanation..
Sir, when you pull SDA low to start comm... SCL starts generating clock pulses or you have control SCL thr' s/w to read or write data ????
Awesome explanation
Keep making these videos
Thank you sir, for this video about i2c it is really good
Good information u have given

I need complete info regarding i2c, please provide
cool sirji. I like your english
Great
Very nice explain thanx sir.
can you prepare a video with i2c frame diagram like start and stop and i2c read and i2c write
Thank you Debidatta Gouda...
Thanks for your meticulous explanation on I2C. Expecting more on embedded. When ?
Excellent, many thanks to share this information.
Thank you Abhijit RASHINKAR
wonderful explanation about i2c basic...thanks..
Thanks Karthick
Sir, please tell me the is it a serial communication or parallel??
which protocol will do parallel communication?
which communication will be used to communicate faster? either serial or parallel.
I2C is serial communication
kalyani perla thank you.... (y)
Superb explanation...thanku so much sir
Thank you Manisha Zade...
I m confusing where we can UART and where we used I2C.but after watching this tutorial i clear my doubts.
thank u
nitin
clear and good explanaition
My left ear found this very useful.
super bro .
What about the pull up registers??
Opendrain..
tq sir for this wonderful video,can you please prepare a video on SPI protocal?
Thank you sindu gooda,, I will do it.....
good intro for i2c
SCL is Unidirectional or not ?
yes SCL is unidirectional, SDA is bidirectional
Good explanation sir
Awesome explanation.
Thank you Pankaj..........
Inter integrated ciruit is i2c
No sound sir
thank you for me good use
thanks sridharan
I2c comes under inter protocol
thnk you sir...
Thank you Jayraj Kateshiya, Keep learning
u people r only theoretical guide

Ek hi sentence kitni baar repeat karoge sir?? Such a boring video
