Bro you're the best
Thank you This is exactly what I wanted

[@thefrugalengineer8396]

Glad I could help

Very Impressive!!!
Can I use voltage divider
with R1 = 220 ohm and R2 = 220 + 220 ohm instead of
R1 = 1 kilo ohm and R2 = 2 kilo ohm, in the HC-05 connection with the arduino uno?
Or do I need 1k and 2k resistors?
Since, Vout = Vin ( R2 / (R1+R2) is the same, it's 2/3, I could use R1 = 220 ohm and R2 = 220 + 220 ohm, right? Help, I am an enthusiastic begginer with this!

nice bro..

ı cant upload codes
did you use usb port cable while uploading or something else

Hi, Can I use this method to control stepper motor? Thanks

[@edosullivan7165]

Muchas gracias! That's exactly the thing I wanted for my daughters project!

You mention to contact you if we have question. But how can I contact you? I code with this example and the HC-5 is found linked devices but I cannot connect. Please help

[@Daniar5588]

brother, is this suitable for Android 12 or higher?

[@franz3810]

thanks :)

hi! the code works very well on the pc, but the app is blank to me after selecting the terminal mode. do you know why?

[@rohitneogi9645]

same plese reply

[@GoogleBabaAnkur]

will it work without any resistors?

[@thefrugalengineer8396]

Hello, no, it wont, at least not with that component and the Arduino Uno, maybe if you have the Arduino Mega you can connect to the 3.3 volts inputs/outputs, but it will require some analysis. Just out of curiosity, what's the problem with the resistors? they are super cheap and easy to get. Thanks
