Nice video presentation, some points to comment:
The HC-05 module used in this tutorial clearly states "3.3V LEVEL" at the RX input pin 0:59 . The use of a voltage divider (1k/2K) is recommended.
Also a resistor (470-1K) in serie with the LED is recomended. (The Arduino ATMEGA328 is being stressed out of specifications).

ТЫ весь интернет перерыл и только по твоему гайду смог нормально подключить этот модуль!

Ya it's working 👍👌 but you have to install Arduino blue control (made by pcb way) and data will be in a 1 & 2 so accordingly our code we have to change it with(small) a and b, thanks for the code and circuit❤✌️

Thanks a lot! I have been looking for videos for starters for a long time and here a got one finally. Great effort and hence lots of appreciation for you.

This was exactly what I needed! I'm using 2 nano to control one-another through the serial communication. Thanks for your help!

Tnk u...it helped me a lot....keep uploading such valuable stuffs 😀

Thank you for your video i am form Thailand <3

+1 for 7:14 tip! Removing RX/TX pins before uploading!

[agrafika]

Thank you..with this program and a bit editing, i can also control 04 channel Relay Module.. 👍👍👍

[annibot]

THANK YOU SO MUCH! You provided me with the easiest code...

[josephjeanclaude]

Thanks, my HC-06 work very well with your explication.

instructions not clear, I was feeling lost during the process. My teacher failed me because of you. THank you sir. I will send you my paypal if you want to repay the tools I broke during the process

Oğul hocanın öğrencileri hepiniz hoş geldiniz :D

Hi ! Good video ! But you are conneting the LED without 220 Ohms resistor to a 5V supply ! This can damage the LED or worse still the Arduino Pin . Take Care !

[rajdeepparmar]

bro thanks i was in problem and by your code i overcome thanks you so much

If you get strange characters, try to change baud rate to: Serial.begin(38400);

that camera was making me rage idk why

great video. the hc-05 logic level is 3.3v. the arduino logic level is 5v. thus, you can connect the Tx pin of the bluetooth module to the Rx pin of the arduino because the arduino also aupports 3.3v logic level. but, in order to connect the Tx pin of the arduino to the Rx pin of the bluetooth module, you need a voltage divider in between. the 5v logic level of the arduino can damage the bluetooth module.

Good explaination and demo, thanks a lot friend

Thanks, good video...please give us more good videos
