Please make the course available in English..

[@ujungdelapan1067]

sir please make metal detector with theory explaination

[@nelsonnegrinho2889]

Thank you so much for this masterpiece!!!! I am definitely going to watch all of the episodes. Please do not stop making these videos until the series is complete.

[@gian-227]

IMPORTANT: if you have copied and pasted sources be careful because the PWM example source provided by the author has an error. Indeed it lacks the TCCR1A configuration "TCCR1A |= B00000111;" in the setup... In the video it's present but in the source file on the website it's not. However, very detailed video! Nice work!

[@Kang38290]

YASSSSS!! iwanted to learn about this for such a loonngg time!!!

[@doctorgreatengineer6834]

me too man

[@gudimetlakowshik3617]

Exactly, me tooo

[@mechee1747]

Amazing explanation of timers! I gained a lot of new knowledge on it where it was pretty much a black box to me before!

[@user-ln6zl6od8x]

This video has been a lifesaver for me.. I really couldn't figure out the ocrna values for such a long time and this video has helped me alot.. thank you for this eye-opener:)

[@stever3886]

Probably the best video I have seen on this topic! Great explanation a little fast paced for me but I can watch the video again. Thank you for sharing your skills and knowledge. I think I could apply this to control the speed the servo arm moves. Currency using delay but I have to get away from delay and advance to this method.

[@shanesrandoms]

Always enjoy your videos on electronics..always able to learn something or understand something better. Keep up the great videos.

[@Balgenwatz]

This truely is a masterpiece. This is gods work

[@vsapre80]

Very nice explanation. In a recent project, I had created an timer event based cooperatively scheduled setup of tasks, based on a basic timing tick of 1ms, using a timer other than the one used by delay() etc. Interestingly, it works very well. As long as you develop and use all timing functions based on your basic time tick. The use of Arduino delay(), millis() is then prohibited because though the timing tick interrupt would work, any calculations done in the ISR would not function, if the delay() is going on.

[@soumitratewari483]

Sir we never miss your any of your videos. We watch them all. Your teachings are great !!! Thank you Sir.

[@advanceringnewholder]

This is by far the best explanation on how to use a timer. At least for me

[@talhaakhtar6172]

Soo informative and easy to understand... Reflects your understanding on this topic... And not to forget about the added animation helps a lot to a beginner like me...

[@anuragmahajan5919]

Thank you for this video, I just love the explanation, you cleared up so many things for me and that too with code! Thank you!

Excellent.

[@ranganatennakoon]

101 thanks !!!

[@mtalhakhalid1679]

good video sir similar to 8051 microcontrollers i use interrupt and timer in that unfortunately 8051 had 2 timmer and 2 interrupt 8 bit register

[@gustavosilva3149]

Great video, thank you for the explanation. I would like to know if the same code could work in Arduino Mega?

[@uvrjj]

Superbbbb

[@nektarioskourakis8331]

Great work ! Can you show , create a nanosecond timer ? For example Trigger a device ,start timer, and stop it when a analog pin pass a threshold . Thanks

[@sreeharibalachandran]

Superb Video :) Thanks :). Is it possible to use timer 1 (16 bit) to create a function similar to micros(), having 1us resolution?

[@YouGenom]

Nice video thanks! The timer 1 (second timer 16bit) animation should go to 65535 instead of 65536 :) Edit: another typo later in the table.

[@vipinchoudhary2787]

Hi, Yours video are more informative than Great Scott's video. Please make a video on advance universal program that can be used for any program. Same program is available on EE Enthusiast KZbin channel. If you can explain the each part of that program in depth and some better modification ,that will best video of your channel. I hope we will get notification of that video soon. Keep doing good work👍. Regards Vipin Choudhary

[@techieelectro]

What's up my friend 😊👍

[@omkharde2325]

Please make a video on how to upgrade your 6 channel transmitter to 10 + channel.😃

[@manoftheday1]

Thanks for all your efforts but please when are you going to conclude your mppt video am waiting for its final part please.

[@aniveshchaturvedi9886]

Sir we want to make a time totolizer for arduino means it should not reset if power ofd. Relay need to high after set time

[@RicciLuca-ATSsrls]

very interesting video congratulations. I'm Italian and I wanted to ask if you can somehow enable subtitles for easier understanding Thank you

[@micah2936]

So with a prescalar max of 2^10 and a clock speed of 16x10^6, and a 16 bit timer, the max interrupt time interval is only 4194 ms. If we let T be the timer compare value, P be the prescalar, C be the clock, b be the number of bits in the timer, and u be the desired delay time, we can write a function of TP=uC where T

[@saneeshelectronica9293]

i have an encoder giving 100 - 400 pulses per second channel A & B my speedo meter has 5% error i need to increase 5% frequency after feeding to Arduino and get frequency increased by 5% both channel A& B. could you please help (for examble 100 hz becomes 105 hz both channel)

[@gokuzraj2566]

Hi electronoobs! The last video you uploaded on rasbi pico was a ELECTROBOON!!! Could you please do projects on rasbi pico . it would be awesome!!!!

[@shrikantnikam2426]

can we use timer 1 for more than one interruption at same time?

[@newbie952]

Is there any library we need to define before the code?

[@SumitSharma-do8ye]

Which software u use for animations

[@saurabhgawli2167]

Sir. Plz do a video on long range wired sensors and long range LED PWM control and power supply. Plz sir..

[@ishanimakwana5972]

what should be the value of pulses for 500microseconds???

[@Electrologia]

7:25 How can I find PWM register control? Would you please make a video? :) Thanks

[@cemyasam]

Hello brother, congratulations on your very successful content. Can you activate subtitles in the video? I can't understand because there is no subtitle

[@FIXDIY]

جيد

[@AtiqurRahman-gj6mg]

Best

[@08acbest]

Actually, 11:35 the correct value of OCR1A should be 31249, check the datasheet. Also, 14:59 the analogWrite function has 10-bit precision, not 8 bits

[@benwhite2429]

If you have too many calculations such as sensor readings in the interrupt routine, is it possible it will take too long to read them and interrupt itself?

[@benwhite2429]

Awesome video by the way!!

[@DIYwithBatteries]

Heyyy 😃👍

[@bobmirror7164]

Is there any open source code for Arduino to open and close a house window with a stepper motor actuator 10 or more times in a day; code that one can edited the hours to open and close a house window? Maybe someone made a library to do this. I can not find anything.

[@nicholastzane3466]

Very nice video. Just a little more explanation please on 10:47 1) You say that TCCR1B |= B00000100 is the same as TCCR1B = B00000010 Since we set TCCR1B = 0 why doesn't TCCR1B |= B00000100 equal TCCR1B=B00000100 ? 2) You say that TCCR1B |= (1
