We have already seen how to connect arduino uno to NodeMCU (ESP8266) here . In this blog we connect Arduino UNO with ESP32. When connecting UNO with nodemcu we

We have built a home automation system using NodeMCU here. In this post we will try to replicate same system using ESP32. We will connect couple of LEDs

In IoT, there are are two components – Embedded device (edge) and application on cloud. Normally server components are hosted in cloud to have better performance as explained

Introduction: In IoT, it is important to connect two components using server. Typical way is to use HTTP protocol, because it is easy and became defacto standard. However

We had fun controlling the servo position from computer in the previous post, but my friend Siva says this is mobile era, everything has to be controlled by mobile

The real power of ESP32 is it’s ability to connect to the network. In the previous blog we have jut seen how to control the servo using ESP32,

We have seen how to connect to a AP in the previous post, in this post we will hose to open a TCP connection with a server. Why

We have connected to existing network using ESP32, we have sent messages to a TCP server running on different machine in our network. Now it is time for

There is no fun in IoT without a network connection. Lets connect our ESP32 to a WiFi access point. In this post we will connect to given SSID

In the context of multi processing, task synchronization is very important concept. In this post we will see how to use event groups for task synchronization Task Synchronization
