PIC Microcontroller Tutorial : LED Blink (Video) And Program SImulation

Today we are going to experience a tutorial on PIC microcontroller’s.

We are using Micro c software for understanding the language and also shown in detail how to debug and program on the chip.

This video tutorial explains you how to open a new project in the Micro c IDE, and the example program which we will see  is led blink.

So we blink an led using a pic microcontroller program.

After writing the program this video also shows you how to simulate  the program on the chip using the Pic Simulator IDE

Also video shows how to select a microcontroller to program on chip and then it’s different registers inside it.

we are going to select the pic 16f series of the microcontroler and then program it.

U can watch the video for detailed information

LC Tank Oscillator : Oscillator Tutorial

Oscillators are one of the very important aspect of all the elctronics equipmets present these days.

When it comes to oscillators there are many kins of its own. The very common oscillator we can find is inside the clock which is a quartz crystal which controls the clock.

the other main thing we need to discuss about is the tank circuit, and u can find it in basically all types of radios.

A tank circuit consists of an coil and an capacitor connected

Actually how it works is when the capacitor charges and discharges through the coil it stats to build a magnetic field. there will be the maximum field

built when the capacitor is fully discharged.

now when the capacitor starts discharging the magnetic field which is buit prevoiusly will start to decrease till the capacitor is fully charged. u can see in the figure below

so again when th capacitor is charged the magnetic field is built but now in the opposite direction. this produces the positive and negative oscillations in the tank circuit which further results in a

oscillated output wave.

Transistor Tutorial DC Bias: Bipolar Transistor Tutorial

In this post we will see about transistor tutorial dc bias. Bias establishes the dc operating point

for linear operation of an amplifier.

If an amplifier is not biased with correct dc voltages on the input and output, it can go into

saturation and cut off when input is applied.

The below figure shows the effect of proper and improper dc biasing of an inverting amplifier.

Now we are going to see the graphical version of the transistor dc biased circuit with a transistor.

In the figure the transistor is biased with variable voltages Vcc and Vbo to obtain certain values of

Ib, Ic, IL and Vce the collector characteristic curves for this particular transistor are shown in the

figure

So in this post we have learnt about Transistor tutorial dc bias.
