i am a student from 2nd semester BCA (Bachelor in Computer Application). My group need some project for presentation from c programming language so i thought of using #ARDUINO project for our presentation . i really don't have any idea in this project so any ideas, answer, guides will be helpful to us.
Good luck with this! Arduino is awesome. I really enjoy using it. You may find this at least a little insightful: http://www.electricrcaircraftguy.com/2014/01/the-power-of-arduino.html.
Arduino is a small computer. It can do essentially whatever you want it to do: drive robots, fly airplanes, control motors, turn on or off TVs, get on the internet, make a home alarm, buzz a speaker, make a touch lamp, fade LEDs, play music (even with no music chip; just using a skillfully-written library), control HollyWood action cameras, talk to your smartphone, read your heartbeat, make a bike speedometer or odometer, read a GPS receiver, etc. Cool stuff!
I am not going to list example-projects as the possibilities with an arduino are endless. If you are looking for inspiration: take a look at websites like www.instructables.com and www.hackaday.io. Those are websites with mostly starter arduino projects that contain step-by-step guides on how they are created. I would suggest that you browse through those projects and look for something that peaks your interest and then think of your own similar project. You should however think of a project with a certain complexity as it is for your bachelor's. Most projects on instrucables lack the challenge. For getting parts: take a look at ebay. Ebay has some webshops that sell arduino's and arduino extension modules really cheap. Good luck
