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

hc-05 is connected but there are no text in terminal

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!

Will the Arduino Bluetooth Connector detect other components like the accelerometer?

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

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?

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

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

I don't have 2k resistor will it work with two 1k resistors

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