How long it gonna take to build a simple end-to-end IoT application ? , lets find out. In next couple of blogs I will try to build a

In this post we will try implement the first iteration solution that we discussed in previous post. Read the previous post for setup instructions. In first iteration we

We can program NodeMCU (ESP8266) in several ways. Most of the times I use it with lua (with nodemcu firmware inside it). We can also program NodeMCU hardware

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

Most of the applications involved with ESP32 requires some sort of data transport, means the device should be able to send data over network to some other device/system.

Objective : In this blog we will demonstrate how to build end to end IoT application using ESP32 board and MicroPython as language. What is required: ESP32 development

Nodemcu has about 8 IOs. For most of the task this might be enough,NodeMCU IO extender comes into picture if you want to more number of output pins.

If you are using paho android mqtt client, you may get the following error if the broker is down or the client is not able to connect to

In a recent hackathon my team developed an application that can be used in lifts , to improve the user experience. Along with Arvind Raman, Sankar, Sachin Ranka,
