In this tutorial we are getting data from web browser using HTML forms. ESP8266 is configured as server. When user clicks on button or text box data that we want to read it in ESP8266 (NodeMCU). This is we are demonstrating in example. before moving to ESP8266, let’s understand basics of HTML forms.

In IoT, LCD is rarely required, but some times its useful to monitor errors and connection related issues. In this tutorial we are interfacing I2C LCD with ESP8266 or ESP32. Both code examples are given.
We have very few IOs on ESP8266 and ESP32. I2C based display interface uses only two IO lines.
Converting ESP8266 IP address to string or character array. There is simple way to convert IP address to string is using toString() function.
WiFi.localIP().toString();
In this tutorial we learn how communicate between two Arduino using low cost 433MHz wireless modules. These modules are also available in long range in kilo meters. It uses ASK (Amplitude Shift Keying).

For professional electricians and hobbyists alike, having the best tools make the actual work experience to be desirable. Just pause for a while and think about what the opposite could be. With the best tools, you don’t have to exert more energy. In other ways, having the best tools will save you time while leading the most productive outcomes.
