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
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
ESP32 has many features/APIs that are not available with ESP8266. Few my favorites are timers API and LED control API. It can do lot fun stuff with servos.
Timers are very important peripherals in embedded systems. If your application depends on precise timing, then timers are only thing that are up for that job. ESP32 provides
