One of the main reasons why Arduino is very popular with beginners is that it is completely self-contained which makes it very easy to use. Once you have an Arduino board, all you have to do is to download the software and within minutes you can make your first led blink. The software has everything […]
This is part 4 of my “Building Robots using Arduino” tutorial series, explaining how you can create robots using Arduino. In this article we will see how we can control the speed of the DC motor using Arduino. Recap Last week, I explained how we can control the direction of DC motors using the H-Bridge […]
This is part 3 of my “Building Robots using Arduino” tutorial series, explaining how you can create robots using Arduino. In this article, I will introduce the H-bridge IC L293D and we will also see how we can use it to control the speed of the motor. Recap Last week, I introduced DC Motors and […]
This is part 2 of my “Building Robots using Arduino” tutorial series, explaining how you can create robots using Arduino. In this article, I will introduce DC motors and how to use them. Types of Motors If you look at the Wikipedia page of DC motors, you will realize that there are different types of […]
I am starting a new series of articles explaining how you can create robots using Arduino. These are the same robots, that I used in my various talks. I am planning to post the article every Friday, so that you will have enough time to try it out over the weekend. Assumptions I am going […]
I was following news about Maker Faire in Twitter today and was quite surprised when I came to know that Massimo Banzi co-founder of Arduino, announced Arduino Yún, a new product that combines Arduino and Linux. Specification I was quite excited and quickly checked the specs. It is a combination of Arduino Leonardo (based on […]
When I wrote about choosing the correct display cable for Raspberry Pi, I mentioned that you might face problems with getting audio, when you use a cheap HDMI to VGA converter, that doesn’t support audio. Problem I use this cheap HDMI to VGA converter which I bought from Amazon, which doesn’t support audio. I thought […]
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 […]
