Wireless Communication of Multiple Variables Between 2 Arduinos Using HC-12

In this tutorial, I will show you how to achieve wireless communication of variables between 2 Arduinos using the HC-12 module, that operates from 433,4-473 Mhz. HC-12s are wireless modules for arduino to arduino communication, because they can send multiple variables over long distances-ones up to 1km-using only 2 digital pins, not even PWM pins,

Esp32 Lora Sensor Monitoring With Web Server (Long Range Communication)

I’m a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32. The LoRa communication capacity of the board opens up a web
