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 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
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
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.
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
