Using Wi-Fi Manager on NodeMCU to Scan and Connect to Wi-Fi Networks

In this project, we are going to use NodeMCU, and program it to operate in two different modes, namely Access point (AP) mode, and Station (STA) mode. In AP mode, NodeMCU will work like a Wi-Fi router emitting its own Wi-Fi signal, you can use any smartphone to connect to this Wi-Fi network and open a web-page in which we can configure the new Wi-Fi SSID and Password, once the new credentials are set the NodeMCU will automatically get into Station mode and connect to this new Wi-Fi. The new Wi-Fi SSID and Password will be remembered so that the device get connected to this network every time its normally powered on again.

Overview of PLC and Various Arduino based PLC Boards

Inrush Current Limiting using NTC Thermistor
This is an article from the sequence of our articles in which we have been discussing about inrush current. We have already covered the basics of inrush current and the various types of Inrush Protection circuits in our previous articles. The most common method of inrush current protection is by using an NTC Thermistor, so in this article, we will discuss more on NTC Thermistor and how to use one to prevent Inrush current in your designs.

DIY Arduino Pedometer – Counting Steps using Arduino and Accelerometer
Pedometers are the devices that only used to count footsteps. So in this tutorial, we are going to build an easy and cheap DIY Pedometer using Arduino and accelerometer. This Pedometer will count the number of footsteps and display them on a 16×2 LCD module

This is an Arduino based QR code generator showing the QR code on SSD1306 OLED.

New Open-Source Standard being developed to Increase Compatibility among Smart Home Products

Amazon, Apple, Google, and the Zigbee Alliance have joined hands to form a group called ‘Connected Home over IP’. The project aims at developing and promoting the adoption of an open-source smart home standard to make it easier for manufacturers to create new devices that work together.

ESP32 Based Webserver for Temperature and Humidity Measurement using DHT11 Sensor

Today we will build an ESP32 based webserver to display the temperature and humidity values from the DHT11 sensor. ESP32 board will read the temperature and humidity data from the DHT11 sensor and display it on the Webpage. Here the IFTTT is also used to send the Email notifications when the temperature goes beyond a particular limit.
