Simple Battery Level Indicator Circuit Diagram. Simple 12v battery status indicator circuit diagram. Mini fm transmitter circuit up to 50m range.
The first design is a 4 step led voltage monitor circuit using the versatile ic lm324. Likewise when comes to 50 battery level the circuit still gives effective output indicating 51 or 53 of charge may be which is still good. The circuit works this way if the battery is at 75 all the green yellow and red will lit up which indicates the battery still holds 75 of charge.
The battery level indicator demonstrates the status of the battery just by switching on leds.
6 th and 7 th pins of ic are connected to the ground through a resistor. Here is a easy to build low battery level indicator circuit that produces a visible indication by flashing a led when the battery voltage drops below a predetermined voltage the circuit is based on panasonic s ic mn13811g and a efficient flasher based on transistors q1 q2 here when the battery voltage drops below 2 4 v the output of the ic is. Mini fm transmitter circuit up to 50m range. This circuit is simple battery level indicator circuit.
