Hello, I am bulding an alarm clock in arduino and followed the elegoo Alarm Clock project on youtube. Currently I am trying to add IR Remote control to it. The code itself works, but I keep getting this one problem:
Tone.cpp.o (symbol from plugin): In function timer0_pin_port': (.text+0x0): multiple definition of __vector_13'
libraries\IRremote\IRremote.cpp.o (symbol from plugin):(.text+0x0): first defined here
collect2.exe: error: ld returned 1 exit status
exit status 1
Error compiling for board Arduino Mega or Mega 2560.

Does anyone have any advice? BTW I am like somewhat new to Arduino

You've got too many libraries chasing too few timers in the code you didn't post.

this is without including the irremote library. If include the library then the error message comes

How do I add more timers if thats possible? Thanks a lot for the help!
