When the procedure needs to be implemented at greater distances the task gets a bit complicated. However the distance between the two windings inside a transformer is very small and therefore the actions take place very conveniently and efficiently. The best example is our regular electrical transformers, where an input AC is applied at one of its windings and an induced power is received at the other winding through magnetic inductions.

The following points outline the concept, and help us to know how the above procedure actually takes place: Induction as we all know is a process through which electrical power is transferred from one position to the other without incorporating direct connections. However researchers are trying their best to find appropriate set ups which may become just suitable for implementing the above concept successfully. Here we are talking about several watts or probably several hundreds of watts that needs to be carried without any dissipation, from point to the other without using wires, an issue difficult to implement. However the concept isn’t that easy as it sounds to be, because with radios and cell phones the transmitted power is merely in few watts and thus becomes quite feasible, but transferring power (wirelessly) so that it can be used for powering high current devices is entirely a different ball game. Inductive power transfer is one such interesting concept which facilitates power transfer without the use of wires, or rather wirelessly.Īs the name refers to, inductive power transfer is a process through which a certain magnitude of power is transferred from one fixed place to another through the air without using conductors, just as radio signals or cell phone signals are transmitted. Lcd.Today the world is getting hi-tech and the electrical systems are also transiting into better and hassle-free versions for providing more convenience to us.

The Arduino Uno ADC is of 10-bit resolution. If only five LEDs are on, the batter is at half strength.

So, if all ten LEDs are lit, the battery is at full strength. The values we convert will display on the LED bar graph where it can project the strength. Then, we can convert the analog value into a digital voltage value by using the ADC conversion formula. The Arduino's analog pin acts as a simple voltmeter where the voltage value is retrieved. It can be understood as the amount of voltage contained in your battery. It is good to understand that batteries have what we call a level of charge. How Does This Project Measure the Battery Level?

Like any other LED, when connecting the LED bar to your microcontroller, you have to connect the anode pins to the positive side and the cathode pin using a resistor at the end to ground. In our project, we will use it as a battery level indicator. It has various applications including audio equipment and industrial control panel. The LED bar graph is an LED array of 10 individual LEDs with 10 output pins.
