Projects and Demonstrations

Here, I will be discussing and demonstrating some projects and ideas that can be implemented or I have implemented. I would also like to request my students and followers to share their ideas and implementation flow so others can also benefit and gain knowledge. Sharing , commenting and discussing can lead to more innovations, collaborations as well as improvements.

Microcontroller GPIO

Image
A general-purpose input/output (GPIO) is a digital signal pin on an integrated circuit or electronic circuit board(In our case, a microcontroller or arduino board) whose behavior—including whether it acts an input or output—is controllable by the user. GPIOs have no predefined purpose and are unused by default. If used, the purpose and behavior of a GPIO is defined by the user or the developer. These pins basically act as bridges to interface with the outside world. For instance, a LED can be connected to these pins as an output device or a sensor can be connected to GPIO for obtaining some input which can be processed by the microcontroller. However, these pins should be made available by the board manufacturer so that they can be used by developers and prototypers. Arduino also has many GPIO pins available for users to program and interface. The pin number and location can be found on multiple diagrams available on the internet. You can see the different pins as well as ...

Leap Motion

Image
The multi-touch desktop is a (miserably) failed product due to the fact that hands could get very tired with prolonged use, but  Leap Motion  wants to challenge this dark area again with a more advanced idea. It lets you control the desktop with fingers, but without touching the screen. It’s not your typical motion sensor, as Leap Motion allows you to scroll the web page, zoom in the map and photos, sign documents and even play a first-person shooter game with only hand and finger movements. The smooth reaction is the most crucial key point here. More importantly, you can own this future with just $70, the price of a premium  PS3  game title! If this device could completely work with Oculus Rift to simulate a real-time gaming experience, gaming is going to get a major make-over. Seriously, a great technology indeed!!

Uploading your first Dummy Program on Arduino

Image
Now, with everything setup, plug in your Arduino Board. If the drivers have been installed successfully, the PC should detect the board. Under the "Tools" option in the IDE, select the "Board" option and from the sub menu, select Arduino UNO as the board. Again, select "Port" option from the "Tools" menu and select the com port that is present there. In case of  multiple com ports, you will need to check in the Device manager to which port the arduino is attached to. Now, Simply Click on "New" under the "File" menu to open a new sketch. Alternatively, click on the "New" button below the toolbar. Don't worry about writing anything in your sketch. Let's first upload the blank sketch and check if the upload is successful or not. You can follow the video below to see a video guide for uploading the program. When you click on Upload, first an operation called compiling takes place. Compiling basically checks...
