So let s get started with our metal detector circuit using 555 ic. The circuit also uses some other active and passive components with ic 555 like coil and buzzer for the indication and alert. The 555 ic timer here acts as a square wave generator and it generate pulses with frequencies audible to human.
In this article we are going to discuss a very simple metal detector circuit using ic 555.
