Great tutorial. Easy to follow. Thanks so much. Just a note from what I have read on other pages. The TX and RX pin on the arduino board output 5V. The HC-05 RX and TX pins can only safely accept 3.3V. A voltage divider is required to bring the voltage down on the output of the TX arduino pin from 5 V to 3.3V going into the RX pin on the HC-05 so it doesn't damage the module.
Yes, it worked eventually and after many attempts, it finally connected, but even though it was connected, my punctuation in the program let the side down! I put " instead of ' when defining 1 and 0 for on and off. I live in Spain but being British, when my original keyboard ceased to function, the new one I purchased, locally of course is for the Spanish alphabet. Just a point to note if anyone has a similar problem.

Thanks for the video. Please share the app name that we can install for iPhone.

Thanks bro for sharing such a very fantastic knowledge, be blessed.
So nice of you
Hey, when adding the device in bluetooth settings it is not showing!!! What should I do???
having the same issue rn. If i find out what im doing wrong i’ll let you know
@@maizoom3499 hey I don’t know what is the issue but HC-05 never worked for me. After that I used Bluetooth HC-06. HC-06 works perfectly.
بسم الله ما شاء الله
ربنا يوفقك في الحاجات دي و توصل للبليون مشترك ان شاء الله
الله يبارك لك شكرا على التشجيع
can i have the coding
Very good tutorial.
Glad you liked it!
I am working on a school project. Can you help me?
Thank you
You're welcome
Why 'char' is used in this coding?
The function read returns one character (char)
Not working sir
