Prologue

•This presentation is aimed at enlighten

engineering graduates about the existing

opportunities in the field of Embedded system d

•This presentation focuses on details of

hardware and software aspects involved in the dembedded products.

•t also explain the re!uired s"ills to achieve su

this field.

contd

•t is my personal observation over these years

many students are not aware of the lucrativeopportunities available in the field of Embedde

Systems .

•#ost of the graduates go after the popular $T

industry to see" a good career.

Probably there may be two reasons for this

i& 'ac" of awareness (

ii& Entry barrier.

•During their education most of the students ma

across the name $Embedded Systems%. )ut thnot be aware of $what is an embedded system

do they wor"* what "nowledge and s"ills sh

ac!uired to build a good career in the f

embedded systems and which companies are w

in this field etc .

• very important point to be observed here is en

barrier to the T industry is very low.ny fresher with a basic s"ills and "nowledge c

level salary.

•Then what are the s"ills re!uired for this8•The answer is simple you must have some soft

s"ills i.e programming and good understanding

processors 9 microcontrollers and sensors etc.

•1nowledge about sensors *their interfacing is a

needed for the design of the embedded product

•bove all the most important re!uirement is th

passion for this core domain field.

•Coming to software s"ills you should have somabout programming especially embedded C and

advanced languages li"e 2ava* Python in additio

languages li"e python which are very easy to le

•nother advantage is that these are low-cost

development boards.• n recent times most of the applications are bu

around such type of controllers.

Conclusions

•So* to shine in the field of embedded system de

you need the passion for design with interest in

new languages and creative mind to implement

ideas.

•s the number of companies is exponentiallyincreasing day by day with the embedded produ

there will not be any hurdles in getting employm

these fields as long as you show interest.
