Most of the time, the data from a sensor in an IoT application needs to be recorded. This data logging is important for later statistical analysis now most popularly known as data analytics. In this tutorial, we will record the data captured from the sensor to a spreadsheet. Let’s build …

We set up a simple NodeMCU web server in our previous tutorial. There we controlled an LED from a web page hosted by the NodeMCU ESP8266 board! This time, we’ll be displaying data from a sensor connected to the NodeMCU’s analog pin.

We’re done with basics of the NodeMCU in my last post. Now it’s time to use the NodeMCU like how it’s meant to be: an IoT device. Here I will show you how to create a simple NodeMCU web server which will control a LED attached to one of the NodeMCU’s …

The NodeMCU is a development board featuring the popular ESP8266 WiFi chip. As it turns out, you can program the ESP8266 just like any other microcontroller. Its obvious advantage over the Arduino or PIC is that it can readily connect to the Internet via WiFi. However, the ESP8266 breakout board …

If you’ve coded PICs before Arduinos one of the things you might have noticed is the lack of function on the latter to manipulate multiple pins at once. Manipulating all the Arduino pins at once is needed, for example, when using a seven-segment display or creating strobe lights. Is there …

One of the strengths of the Arduino platform is its extensive library. Libraries make life simpler for coders; imagine how hard it would be if there’s no LiquidCrystal or Servo library ready for use. In my experience, projects took shorter time because of the built-in and third-party Arduino library you …

If you want to do serial debugging for your PIC, ESP8266, Bluetooth module and a TTL-to-USB converter (pictured below) is nowhere in sight, you can simply use an Arduino USB serial converter!   The Arduino UNO has its own FTDI chip whose function is to convert TTL signal levels to USB. …

The Internet of Things (IoT) revolution has inspired thousands of makers to build interconnected systems that span the globe. Want to join the revolution? Learn first how to make a PIC16F877 Internet connection! This tutorial will cover using the PIC with the ESP8266 Wi-Fi module both in sending and receiving …
