Extend WiFi with an ESP8266

You can download our e-book ‘Learn Arduino from Scratch’ from this link The ESP8266 is known for it’s powerful features and performance despite its small size. However few knew it could act as a WiFi extender/repeater. From previous lessons, we learned how to make the ESP8266 act as both a station and an access point. Now we are going to use that functionality at the same time with a little… Read Article →

Arduino Beginner’s Course Lesson 7– Understanding Interrupts

You can download our e-book ‘Learn Arduino from Scratch’ from this link What are interrupts? Well they interrupt something for sure, precisely they interrupt the main program execution of the CPU. In Arduino we have 2 main functions the setup() and the loop(). Interrupts interrupt code execution in the loop(). But why should we care about interrupts anyway? They are not something to be feared, they make your code cleaner… Read Article →

Evothings – Part 1 Setup

You can download our e-book ‘Learn Arduino’ from this link The greatest thing that happened after the introduction of Arduino was the Evothings + Cordova framework. Evothings workbench is both a framework and a just in time debugger. It uses Cordova in its core, and its programming language is the notorious Javascript. Applications are written in HTML/CSS for their GUI and Javascript for their logic, yes just like a website…. Read Article →

ESP8266 Tutorial Part 3 – Running a simple Web Server

You can download our e-book ‘Learn Arduino’ from this link Last time you learned how to connect the ESP8266 to a WiFi network and download data from a URL. Today we will explore a way to listen to connections just like a server; a web server in fact. The ESP will listen for connections on port 80 and will serve simple pages to connected clients. For this example, a different… Read Article →

ESP8266 Tutorial Part 2 – Connect to WiFi and Download from the Internet

You can download our e-book ‘Learn Arduino’ from this link In part one of this series, we gave an introduction to the ESP8266, setting the IDE and the circuitry needed to get started. In this post, we will go through some basic software capabilities particularly connecting to a WiFi network, and establishing a connection to a web server to download data. The ESP8266 is not an Arduino, it is only… Read Article →

The ESP8266 – A Tutorial – Part 1 Environment Setup

You can download our e-book ‘Learn Arduino’ from this link Introduction The Internet of Things is a relatively new concept in the world of electronics. It was also quite expensive and maybe even unreachable by some hobbyists. The introduction of the ESP8266 changed that perception forever. Being first designed as a simple Serial WiFi adapter; today it is the most common IoT device among electronic hobbyists and hackers alike. The… Read Article →

Arduino Beginner’s Course Lesson 6– Reading Sensor Data – Temperature TMP36

You can download our e-book ‘Learn Arduino’ from this link During this lesson, we will go through the process of reading sensor data, the TMP36 temperature sensor to be precise. First lets describe the sensor in  more detail. The TMP36 (ebay) has a linear voltage to temperature output meaning there is no error correction to be calculated from our end, the sensor handles it brilliantly on its own. The following… Read Article →

Arduino Beginner’s Course Lesson 5– Installing and Using Libraries

You can download our e-book ‘Learn Arduino’ from this link Libraries are an essential part in the Arduino world. They are what makes Arduino so easy to use. Libraries are written to encapsulate complex functions and expose them as simple function calls to the user. For example to switch a pixel on and off in an LED monitor. This is relatively very complex but, fortunately some folks at Adafruit created… Read Article →
