Basic Tone Detector Circuit By IC Tone Decoder LM567
If we will study to hook the circuit tone Detector. Should try use the integrated circuit number LM567. Because it convenient is good be IC Tone Decoder especially follow a picture. This circuit is small-sized circuit uses in circuit learning detects sound frequency experience feed at from the circuit produces sound frequency ( the left is ) choose the frequency fo that 1.1KHz approximately as a result make , LED1 stick bright get . By the value fo this can fix with RC at assemble in the circuit.
