Advanced Arduino Code Optimisation with Pin Registers

[@johneagle4384]

Without videos like yours, my projects would be dead in the water. Thank you for the excellent explanation.

❤ From SRI LANKA 🇱🇰❤ I've learnt lot from your channel.. and I think you deserve much much more subscribers, likes and comments

[@bobvanwagner6099]

Well done video presentaton. Thoughtfully done, nice pace.

Thanks, someone has built a circuit with an Atmga8 on it, so I THOUGHT I knew about them. One of the switches on their board goes to pin PC3.. so there I am DRDC &=PC3 your tutorial made me look at PC3 which turns into a 3 hmm thankfully only 3 leds and three switches!!

[@jozefsoucik3115]

great vid. i always need deep understanding to understand the thing. this made me moved forward... Also i learned today, that you can achieve much memory saving by use for delay(1000) function thic code instead: for (long i = 0; i

[@mrtom64]

Nice explanation. Setting PIND also functions as a toggle...eg: PIND = B00010000 will toggle pin 4 each time the code is executed.

[@marios_ideas]

I did not know that:( I would have included it in my video

[@mrtom64]

@@marios_ideas No worries, it seems wrong to 'set' a read only register but it works and is very useful.....and extremely quick. Apparently turning pins on and off is a 'thing' and the challenge is, of course, to do it the fastest.....you'll find lots of weird and wonderful 'port manipulation' code on the subject.

Very good! Congrats.

[@marios_ideas]

Thanks. Don't forget to give video a like. Helps with growing the channel

[@Lunolux]

that was interesting, nice video thx

[@raymondmichael4987]

Fascinating 😊❤

[@alielectronics17]

nice video & nice explanation

[@marios_ideas]

Thx:) Give the video thumb up. Helps to promote my channel

[@thaboluvhimbi4208]

Informative

[@IvanEng747]

This example maybe apply in esp12F?

[@adambeedle]

Great video 👍

[@marios_ideas]

Thx:) give vide a thumb up if you liked it

[@shubham9672]

Is it good or bad 14:40 That pulse

Please make next video on How to create fastest function Replacement for Digital read Digitalwrite Analog write Analog read Delay function

[@Gaminiheraliyawala]

This is fantastic... 👍👍👍 But, what is the IDE? Is it Arduino IDE? Appreciate your reply.... 🙏🏻🙏🏻🙏🏻

[@marios_ideas]

It is Arduino IDE

[@alcanceweb]

Great tutorial, thanks. I'm also interested in your small led modules. Could you please provide me link to buy them?

[@marios_ideas]

AliExpress . Search for lillypad leds. They are generally for electronics to be attached to clothing. But i thought they work great in breadboard projects

[@alcanceweb]

Outstanding. Thank you, sir.

[@marios_ideas]

No problem. Consider supporting my channal

[@Sekhar_Home]

Pls make more advance video on port manipulation and writing of complex arduino codes

[@marios_ideas]

Any particular aspects you are interested in?

[@Sekhar_Home]

@@marios_ideas sctually i need all.. but at first need ADC and timer programming.

[@shubham9672]

Can we use digital pin D0 and D1 as output and drive LED

[@marios_ideas]

Yes

[@shubham9672]

@@marios_ideas But if we attached LED to those pin then is there any problems with Rx TX communication

[@marios_ideas]

You cannot do both. I always thought D0 and D1 are off limits and reserved for RX TX. But with pin registers I was able to use them to control LEDs

[@shubham9672]

@@marios_ideasfor example I built a blutooth controlled robot If I detected any obstacles can I drive D0 and D1 pin to logic low

[@shubham9672]

If I do so .... Is blutooth connection disconnected

[@snouzz-gaming]

Hi great Video! Do you can explain how to write a code with register for nrf24l01 (Receiver & Transmitter) ?

[@marios_ideas]

My pleasure:) like and subscribe to my channal. Also consider supporting it.

[@no5x937]

There is NO IF statement in the first code shown. Register D has 8 bits (NOT 7). Otherwise, great video.

[@marios_ideas]

Point me to the exact timestamps in the video so I can inform about those mistakes in the description
