3.7V Battery Low and Full Level Indicator Circuit - Instructables

NettetLEDs (that's "ell-ee-dees") are a particular type of diode that convert electrical energy into light. In fact, LED stands for "Light Emitting Diode." (It does what it says on the tin!) And this is reflected in the similarity between the diode and LED schematic symbols: In short, LEDs are like tiny lightbulbs. NettetFurthermore, you can use different LED colors to show the battery status. So, connect the red LEDs (D1 - D3) to show when you have a low battery. Then, connect the green LEDs (D8 - D10) to show when the battery is 80% or fully charged. While the yellow LEDs will indicate the other power status. expert holterman
