After reading my recent tutorial on using Arduino code in non-Arduino microcontrollers, one of my readers asked me if it is possible to use Arduino as an ISP programmer to program these micro controllers, instead of using a separate dedicated AVR programmer. The answer is a definite yes and I use it all the time, […]
The first question people ask me these days when I talk about either Raspberry Pi or Arduino is what is the difference between them. This was one of the prominent question that people asked me during my recent PyCon talk and Maker Party presentation. Even though both Raspberry Pi and Arduino are created to solve […]
Shift Registers are one of my favorite devices. It is really fascinating, when you understand how they work. Ever since I learned how Shift Registers work and how you should use them, I was planning to write an article explaining it. While browsing around, I found an excellent video by Kevin Darrah which explains how […]
I had a bunch of ATmega 16A and ATtiny 85 microcontrollers lying around and I was trying to find a way to program them using Arduino code. There are two main reasons, why I wanted to use Arduino code. The first reason was to use the many built-in functions like digitalWrite, digitalRead etc. And the […]
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 […]
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 […]
