I followed this tutorial for a demo code for the SR04 ultrasonic distance sensor (without the LCD display). I've installed the Arduino IDE and wrote the code in it and saved it in some location. Compilation of the code is successful. However when I try to upload the code, I get the message:
Invalid library found in C:\Users\Dame\Documents\Arduino\libraries\arduino_144469: no headers files (.h) found in C:\Users\Dame\Documents\Arduino\libraries\arduino_144469
There are no header files in the directory and I'm wondering if I need to download additional header files or if I should configure something else.
