Learning microcontroller is the most recent fad in the students community with microcontrollers people relate only with Arduino ide and its related components but they tend to forget that to work better and efficiently on interfaces one needs to master the concepts of 8051 family of micro controllers.

To imitate this ideology I have designed a training course on udemy.com and even uploaded free videos on youtube .Im in favour of free and affordable learning to all.The limit of learning should not be bounded by money or any other physical boundaries.

So in order to study any interface one should understand the hardware connection/diagram that constitute the internals of the interface.Then one should understand the pinout that are coming out of the device to interface with the real world .

Then when should proceed to making the connections to the micro controller. First of all let us understand that what are the different types of full numeric displays available in the Industry. There are two types of display common cathode and common anode.

We have simulated our micro controller C Program and then downloaded the working program on micro controller and then run on it.
