This tutorial demonstrates how to build a simple sensor and publish its values online (on a web server) using an ESP32 module. We will build an Arduino sketch which will read the sensor values, connect to WiFi, connect to a…
The ESP32 Wifi module can replace an Arduino, as it has similar properties. It’s main advantage is that it is faster, has more memory and has WiFi and Bluetooth on board. Just like the Arduino Nano it can be mounted…
We are going to build a circuit that is connected to an app build with Blynk. For this we connect an Arduino to an ESP8266 module and connect it through Wifi (step 1). This example uses an Arduino Nano, of…
