To send the high frequency current, we will use the 555 Timer chip configured as a square wave generator. This circuit has little components and is comparably easy to build. It uses only one capacitor and one resistor to set the frequency of the square wave. | To send the high frequency current, we will use the 555 Timer chip configured as a square wave generator.
