how to pass this circuit to a breadboard?

Answer 1

The circuit given is very complex to connect,you need 3 or 4 breadboards.

Connect 4 opamps first,and then make other connections resistors are selected based on their color coding.Use one single ground in the buttom line and 9v line in the top.Connect one piezo buzzer at the input side and one speaker at the output side.Make sure that you pick correct values,start connecting from left to right
