Hello fam

i am adopting this circuit for a cable theft monitoring system i am designing. in the astable multivibrator config ,i replaced the capacitor with various length of  cable and the response was good. however adding other elements like buzzers(pin 12) , ldrs(A0)  and led(pin13) show no response. is it that all the other pins wont function properly , that is even if they do if i use this code
