It is in every IoT (Internet of Things) enthusiast’s desire to build at least one IoT project in their lifetime. However, the cost of building a simple IoT project as well as the knowledge needed might be scary especially to newbies. In this esp8266-Arduino-Thingspeak project, we are going to learn how to build a simple and cheap weather station using the DHT11 temperature and humidity sensor, esp8266 wifi module, Arduino Uno microcontroller, and the Thingspeak open IoT platform, in seven simple steps. 7 Steps to building your simple esp8266-Arduino-Thingspeak weather station Hardware requirements Software requirements Electrical schematic design How to […]

They say a picture is worth a thousand words and I think a motion picture is worth two thousand. Watching a video demo clears the confusion that may result from learning by reading. I happen to be one of those guys who prefer learning by watching especially after studying the theories around something. After writing the article: How to Launch Your ESP8266 WiFi Module into AT-MODE Using Arduino Uno, I found it fit to follow it up with a video demo. The demo specifically demonstrates: How to connect the ESP8266 WiFi Module directly to the Arduino’s 3.3V pin How to launch the […]

Over the last decade, “Internet of Things” has been the hottest topic among geeks and techies. On the other hand, searches for the most cost effective WiFi Modules have also increased significantly. A WiFi Module in the IoT architecture provides internet connectivity. It enables logging of data from sensors to the cloud or IoT platforms. ESP8266 WiFi Module happens to be the WiFi Module in every tech enthusiast’s cart. Why use ESP8266 WiFi Module? The ESP8266 WiFi Module has become increasingly popular among techies and DIYers mainly because of the following reasons: Low cost – it costs less than $10 Small size – […]

My first mobile phone was a phablet-sized “China phone”(but not a phablet for reasons given later). This however doesn’t mean that all China phones are fake. In fact my current one is a genuine China flagship killer. Just after completing high school I bought my first phone at ksh. 6,000 (equivalent of $60) off of some money my mum gave me as a prize for impressive O-Level score. I think that was the best thing people in my village had seen. I was so impressed. The ‘thing’ had LEDs on the edges that would flicker whenever someone was calling (It would […]
