We have already seen how to connect Arduino UNO with NodeMCU/ESP8266 over UART and send data to MQTT broker here.  That project uses lua to program the NodeMCU

I have used micro python on nodemcu for couple of small projects. Micro python is great when it comes to ease of writing code and the read to

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

In this post I will load mongoose OS to nodemcu. mongoose provides a nice browser based editor to edit the code and you can upload the code to

In this blog we will see how to use NodeMCU with Arduino IDE. Once you are done with the setup you will be run arduino sketches on NodeMCU. First

ESP8266-01 version comes with a AT based firmware, you need a application processor/controller to solve a problem. if your use case doesn’t require lot of GPIO (ESP has

In this blog we will build Intruder detector using NodeMCU/ESP8266, more of like a burglar alarm. We will be using a IR reflection based sensor. The sensor working

Azure IoT hub allows direct MQTT connections. So we can use MQTT module of the Node MCU to connect with the Azure IoT hub. You need a SAS

Lua allows to load a string and execute it as code at runtime. We can use this feature to send code snippets to the NodeMCU. There are several

Connecting NodeMCU to twitter: In this blog we will see how to post a tweet from nodeMCU (Connecting NodeMCU to twitter). Making nodeMCU talking to twitter server is
