When I wrote about choosing the correct accessory for Raspberry Pi, I mentioned that choosing the display cable could get a little tricky. There are a lot of things to keep in mind and so I thought of writing a separate guide for choosing the correct display cable. The following are the different scenario’s which […]
Ever since I bought my Raspberry Pi, people reached out to me asking what are the accessories that I am using with it. It took me a bit of research to find out the best accessories needed for Raspberry Pi and I thought of documenting it so that it is useful for others as well. […]
Once of the important things to do when you play around with electronics is to make sure that you are safe-guarding your electronic components from over current. The most common way to do that is by adding a resistor in series. You can calculate the value of the resistor needed for safe operation by using […]
I recently found an interesting use of the many Arduino boards that I have. You can use your Arduino board as a bridge to connect serial devices to the computer, without even writing a sketch. How cool is that? 😉 Before I tell you how you can do it, let me explain about virtual COM […]
TI’s Stellaris LaunchPad board, which I reviewed recently comes with an out of the box demo program called qs-rgb. This program allows you to test the LaunchPad board and also try out some of the features of the LM4F120 MCU that is present in the board. Getting the program into the board When you buy […]
One of my favorite Arduino shield is the USB Host Shield by circuits @ home. Both the hardware and the software of this shield are excellent and well written. I was playing around with the shield by connecting a USB Missile Launcher and had a closer look at the shield. I realized when I had […]
While cleaning my room the other day, I stumbled upon a couple of old toys which I bought from US for myself. (Who said you have to grow up 😉 ) I was going through the packs and found an old USB Missile Launcher and thought of putting it into some good use. USB Missile […]
There is a huge variety of shields that are available which can be stacked on top of an Arduino. Often there are more than one manufacturer for a single type of shield itself. In a way this is good, because as a user you are going to have multiple options. But it becomes a problem […]
In my earlier article where I showed how you can access YQL in Arduino, I mentioned that I wrote a quick and dirty function to do URLEncoding (percent encoding) in Arduino. While writing that function, I found a nice little trick about URL Encoding and thought of writing about it here. At first, I just […]
I guess most of you would by now, know what is JSON. It is a data format to represent structured data like XML, but is very small and has native support in JavaScript. Libraries are available in various languages for parsing JSON. But I was stunned when I read about aJson Arduino library. The author […]
