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 second iteration solution that we discussed in previous post. Read the previous post for setup instructions. In first iteration we did not had

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

Servos are exciting devices. We can get precise posting with minimal code, all you need is a controller that can produce PWM at 50Hz. In this post we

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

The standard ESP32 module (ESP-WROOM-32) present in the market has 512KB SRAM. For most the applications this RAM is more than sufficient. In fact it is nearly 4

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
