Guys, I need the bthc05 library. I couldn't find it anywhere. Can someone send me the link?
If it is the HC-05 Bluetooth module you are looking for then you don't need a library as it is simply a serial device that you can write to and read from
Arduino: 1.8.13 (Windows 10), Плата:"Arduino Uno"
LaserCat:4:10: fatal error: BTHC05.h: No such file or directory
#include "BTHC05.h"
^~~~~~~~~~
compilation terminated.
exit status 1
BTHC05.h: No such file or directory
Showing this
Where did you get the code that you didn't post ? (BIG HINT)
The easier you make it to read and copy the code the more likely it is that you will get help
Please follow the advice given in the link below when posting code , use code tags and post the code here
Perhaps try a Google search on BTHC05.h ?
How hard did you look for the library ?
I am trying to make this project. But the code is giving an error.
Which project ?

So, do you have the BTHC05 library installed and if so where is it located ?
NO it isn't, I couldn't find that lib
See the link in my reply #6
How do I install? Tell me please.
Create a folder named BTHC05 in the libraries folder of your sketchbook folder and put BTHC05.h and BTHC05.cpp in the folder and it will be available to all sketches
Alternatively put the 2 library files in the same folder as your sketch and the library will be available to that sketch
