What is Meshtastic?
A few years ago, James Provost built a handheld texting device, based on Arduino, to send short messages over a connected ham radio set. One of my many backburner projects has been to build something similar, either based on amateur radio (like James’s project) or based on LoRa. Little did I know that Kevin Hester,…

ESP32 – How to Use I2C with ESP-IDF
This tutorial covers the basics of using I2C with ESP-IDF and demonstrates how to read temperature from a simple temperature sensor (TI TMP102). You can watch a video version of this guide here: What is I2C? Inter-Integrated Circuit (I2C) is a synchronous, multi-master, multi-slave serial communication protocol developed by Philips Semiconductors in the early 1980s.…
