I wish to learn embedded systems and programming . Are there any online courses and mobile apps,? I'm a beginner.

So... what have you found already?

@amatrelan thank you so much . Now I have got a clarity what I have to do.

Adding on to @amatrelan, a few other arduino/ raspberry pi projects you could work on are:

Connecting it to your lights to make them turn on automatically (use an electronic switch)

A radio/ music player

Some kind of robot

And there are sensors you can play with for pretty much anything, not just temp

@LavaTheif Thank you . I have one more Doubt what is the difference between 'C', 'embedded C' and 'arduino' programming . I have bought Arduino mega 2560.

I can highly recommend the arduino starter kit.

It contains a couple of sensors motors and stuff and a book that has examples and challenges in it.

@shyamsundhar Embedded is pure, Arduino is a framework for embedded C.

I can recomended Arduino. You can even code a freaking satellite and send it to space!
