There exists a sensor for almost all physical parameters. Temperature? Pressure? Weight? Gas Concentration? We’ve written a tutorial for them all on this site. This time, we will try to build a device that measures rotational position. The same device can measure rotational speed too. Of course, we’re talking about the …

There is, in fact, a way to create a NodeMCU ESP8266 WiFi jammer although technically, this is a deauther and not really a jammer. A jammer sends out noise on the WiFi frequency spectrum (2.4 GHz) while the program in this tutorial sends packets that disrupt the normal functions of …

The NodeMCU is an Arduino-compatible board that features the ESP8266 at its core. It became popular because it is a WiFi-ready microcontroller by itself – no need for an Arduino. This NodeMCU pinout reference aims to show pinouts for NodeMCU v0.9, NodeMCU v1.0, and NodeMCU v3.

You can use WiFi with the NodeMCU (ESP8266) even without a WiFi router. All you need to do is create a NodeMCU WiFi Access Point and the device will now act as a WiFi gateway.

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.

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 …

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 …
