Quick (maybe stupid but I'm curious XD) question. What does HC stand for? I can't find the meaning anywhere else

[@almirbajsini]

Just started with arduino wireless comuniction and im trying to control servo with potenciometer and i dont know where to start i tried looking at any exampe skeches but i cant find any.

Thank you for help Brian.. Have a nice day :)

Great video but the links to the code for this video is dead. Are any links still available or has this project expired?

[@brianpatton7496]

I hope there are working again now...sorry about that

[@peterlangridge1068]

​@@brianpatton7496Code links are indeed up again and very helpful to get my project off the ground. I have given the Vid a like an will follow your channel for more on the subject in future. Thanks again

Hello. Thanks for a great tutorial. I have a question, I copied and pasted the simple sketch into my Arduino 1.8.5 IDE but when I went to verify it I get an error saying 'Serial2' was not declared in this scope. Did I do something wrong?

Steve Tripoli which microcontroler board are u using ?? It can be differs from u r MC and what he actually used.

[@steve8939123]

vamsi krishna Thanks for the help. I am using an arduino nano.

Hi ,one hc 12(master side) can communicate with how many number of other hc12(slave side) devices ?

[@alivelinaveenchawdary6657]

can u send me how to configure one as master and another as slave mode please?

[@vamsikrishna9825]

It can be 100 devices because hc12 is having 100 commincation chanles so u can use them

[@RahulKumar-zs2wv]

If there will be 3 hc 12 how to differentiate between them ,to whom to send data. And then any one can read the data with same frequency ?

[@brianpatton7496]

I give a starting character or two to each unit with an HC12. they all then get or send the signal but they ignore every signal that does not have the address they are looking for..That way one HC12 can talk to lots of other HC12s . They all get it and parse it but only act on it if it is their address.

[@RahulKumar-zs2wv]

means any one hack our data. first reading the address and then writing that address in code to get all the data. Is There any hardware side security like specific Mac address only it can connect .

Is it possible to use the HC-12 with an Android mobile phone.

[@brianpatton7496]

yep. I think there are a lot more choices for app downloads with the Android vs Iphone or PC. Most of my students use their Androids or one of the schools Android tablets

[@brianpatton7496]

Arrrg Sorry I have the flu.....I was thinking of the bluetooth device no the rf device! NO it does not work directly with any android device. However, connecting a bluetooth device to the HC-12 is really easy and fun. Then bluetooth can be converted to RF and works for great. I will try to create a video this weekend on how to do that. Sorry about my assumption on my first reply!

very well done
