Blinking LED using PIC16F877A Microcontroller

LED blink using microcontroller is the first step for microcontroller programmer. It is quite easy for the students if he/she know the C programming. In this section you need to know the embeded C language for microcontroller programmin and also need the simulation software to test the .hex code. the simulation software neme is proteous professional that i used. Several tutorials will be found on youtube if you need to teach the operation and settings.

This was my first microcontroller project which have four LED blinkin secquentially.

Tank Circuit and it's uses in Oscillator

Tank circuit is basically made by an LC circuit. It is also called a resonant circuit, tuned circuit. It is an electric circuit consisting of a capacitor and inductor which is connected together.  Tank circuit can store energy by oscillating at the circuit resonant frequency.

 The frequency of the resonance tank circuit is given below where XL is the inductance -
