WiFi Scanner using PCD8544 and NodeMCU

While searching in my Pandora’s box of electronics, I came across the beautiful PCD8544, or the more familiar name, the Nokia 5110 LCD. This amazing piece of hardware is fully programmable using Arduino or ESP8266/NodeMCU. Thanks to Adafruit and bbx10 for their libraries which make our lives easier. The display has a resolution of 84×48 pixels. Each pixel can only be on or off, so there you have it, a… Read Article →

Extend WiFi with an ESP8266

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 twist. Unfortunately the standard firmware is not capable of forwarding packets between… 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 →

Messing with WiFi protocol, Esp8266 and fake APs

You can download our e-book ‘Learn Arduino from Scratch’ from this link I was browsing the internet on a rainy day, and stumbled upon some cool stuff. The ESP8266, apart from being a super chip, which can be turned into a station and an access point, it can also do some weird stuff at the lowest possible level on the WiFi protocol. wifi_send_pkt_freedom() is a function built in Arduino Core… 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 →
