Components used to make the Battery level indicator circuit:

01. LED Light

Fig 2: LED Light

LED (light emitting diode) is basically a type of diode that emits light at a certain voltage. These LED bulbs turn on at a very low voltage such as 2~3 volts. When the light emitting diode is forward biased, the free electrons in the n-type semiconductor gain electrical energy from the DC source and move from the balance band to the conduction band and the electrical Under the influence of pressure, current flows through the junction to P-type. In the p-type majority of carrier holes are located in the valence band. Thus basically the p-n junction becomes a light source.

02. 1k Ohm Resistor

Fig 3: 1K Ohm Resistor

The main function of a resistor is to block the flow of current or cause a voltage drop in an electronic circuit. In short, the function of the register is to prevent the movement of electricity. When we know about electronics, the first name that comes is Resistor. It is basically a common component of electronics. This component is used in every electronic circuit. A resistor is a very familiar component to those who work with electronics. It has a special function. Resistance is denoted by R. Its unit is the ohm (Ω). The following figure shows some resistor symbols that are used in various circuit boards and circuit diagrams.
