Simple LED indicator for audio signals Circuit Diagram I want to design a circuit that has 3 LEDs connected to it. When the voltage of the power source connected to the circuit is 3.6 volts I want only the first LED to light. 7.2 volts I want the
These are 8 Low Battery Voltage Alarm indicator circuits, as ideas to make small projects, they use LED display easy, cheap with normal parts look below
Electrical Engineering Stack Exchange Circuit Diagram
A simple electronic part such as an LED can play an important role in displaying and monitoring the condition of this AC mains voltage and warn us of a possible electrical hazard. Here, I have explained exactly how to make ac voltage indicator using leds through a construction of a little electronic circuit.
This is four circuits of LED voltage indicator are simple and easy to builds for check voltage battery and others, use as zener,transistor,LM339 and more
How to build 110 and 220V AC LED Voltage Indicator Circuit Diagram
