Iridium Satellite Communication with Arduino

Arduino, GPS, IoT, Satellite

When deploying a microcontroller-based IoT solution or just doing experiments gathering data in the field, you often need a way to get the data back to your home base or to the cloud somehow. You’ve probably used WiFi, maybe dabbled with cellular solutions, but...

Arduino Shield for CAT M1 and NB-IoT Modems

Cellular, IoT

LTE CAT M1 (sometimes called LTE-M) and NB-IoT are both exciting new cellular technologies targeting IoT applications. While there are many modems being built with this new technology, there are not many choices for hobbyists. There are a few Arduino shields and...

LoRaWAN Networking Part 2: Using End Devices

GPS, IoT, LoRa

In part 1 of this series I showed how to set up a simple LoRaWAN gateway, and in a previous article described a simple but powerful LoRaWAN-capable end device that I designed. Now I’ll show how these devices can be used in a real LoRaWAN application. LoRaWAN...

LoRaWAN Networking Part 1: The Gateway

GPS, IoT, LoRa

I have been playing with LoRa modules a lot recently (see projects LoRa Weather Station and LoRa Mesh Networking) and even designed my own LoRa development boards. LoRa is an easy way to achieve low-power, long range radio communication with small payloads. To get...

SAMD21 LoRa Development Board with GPS

IoT, LoRa

Project source code at GitHub: samd21-lora-gps I’ve been doing some LoRa projects lately in order to learn as much as I can about this exciting new radio technology (see this LoRa mesh networking project and this LoRa weather station). ATmega328-based Moteino...

LoRa Mesh Networking with Simple Arduino-Based Modules

IoT, LoRa

Project source code at GitHub: lora-mesh In this project, I will show you how I built a mesh network of 4 Arduino-Based LoRa modules and devised a way to visualize the network’s behavior in realtime. Using a realtime visualization we can see how the network...
