The project presented here is a sensitive sound sensor. The circuit converts sound frequency and outputs DC voltage.  The board consists of LM358 OPAMP and LM2907 IC. LM358 is used as a dual-stage microphone preamplifier and LM2907 acts as a frequency to voltage converter. The circuit...

A rechargeable battery’s load should be disconnected at the point of complete discharge, to avoid a further (deep) discharge that can shorten its life or destroy it. Because a battery’s terminal voltage recovers when you disconnect the load, you can’t simply disconnect the load...
