Arduino with ESP8266 – Reading Data from Internet

The ESP8266-01 has been a great module to quench all our thirsts for IOT projects. Since its release, it has developed a strong community and evolved into an easy to use, cheap and powerful Wi-Fi module. Another open-source platform which is much more popular is the Arduino, it already has tons of projects built around it. Combining these two platforms will open up doors for many innovative projects, so in ...

Driving a DC Motor with an Arduino & the L293D Motor Driver

In this tutorial, we'll be looking at how to power and drive a DC motor with an L293D and an Arduino. Story In this tutorial, we'll be looking at how to power and drive a DC motor with an L293D and an Arduino (we're using the Arduino MKR 1000 here, but you can use any Arduino that provides enough voltage for your motor, and has 2 digital output pins). The L293D is a 16-pin Motor Driver IC which can control ...

Basic Switching Voltage Regulator Tutorial

A switching voltage regulator is one of my favorite circuits. In school, they were the first circuits I built where I understood how transistors worked. In fact, they were the first circuit I saw an inductor being useful! Switching regulators are incredibly efficient when designed properly. Of course, this detail about design is important. They are not as simple as a linear regulator, which is basically an ...

Playing Melodies using Arduino Tone() Function

Arduino is an excellent way to simplify and speed up your microcontroller projects, thanks to its community of developers who have made almost everything look simple. There are lots of Arduino Projects out here for you to try and have fun. Some of your projects might need some sounds action to notify about something or just to impress the viewers. What if I told you that almost any theme songs that could be ...

Control an Arduino Zero using Node.js

I had to delve deep into the code, but I finally got nodebots working on an Arduino Zero Story I recently received an Arduino Zero, arduino.cc’s latest offering. I’d been experimenting with nodebots, so I decided my first Arduino Zero project would be a nodebot. Anna Gerber has an excellent tutorial for doing nodebots using Arduino at http://node-ardx.org/ Not only is it well written and suitable for beginn ...

A Simple Arduino LED Example in Proteus

Hello friends, I hope all are fine and having fun with your projects. Today, I am going to share a very Simple Arduino LED Example in Proteus ISIS. I have designed a very basic example in Proteus in which I am going to blink single LED first using Arduino and then I am going to blink multiple LEDs in Proteus. When you start working on Arduino then Arduino LED example is the first example which you must try ...

L293D Motor Controller Tutorial

L293D is a chip that enable us to control two motors together with only one Arduino board or other microcontrollers. However, I was having a project that required controlling four DC motors together. Recently i brought a L293D Arduino Shields , it covered all of my pins that i need to use them to connect with other breakout board to combine with the motor controller (of course you can buy a L298N motor cont ...

Arduino UNO Tutorial 6 – Rotary Encoder

We have written a tutorial for Rotary Encoders using a Microchip microcontroller but now would be a good time to make an Arduino UNO version. With a rotary encoder we have two square wave outputs (A and B) which are 90 degrees out of phase with each other. The number of pulses or steps generated per complete turn varies. The Sparkfun Rotary Encoder has 12 steps but others may have more or less. The diagram ...
