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...

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...

Overlay GPS Data on Video

Arduino, GPS, Video, XBee

Difficulty Level = 7 [What’s this?] Several people in the FPV RC world (that’s First Person View Remote Control for the uninitiated) have contacted me about the possibility of using a Video Experimenter shield as an OSD solution (on screen display). People...

Speed Trap! A GPS-Based Speeding Alert

Arduino, GPS

Difficulty Level = 9 [What’s this?] This was a fun project I built using a perf-board Arduino with GPS receiver, some LEDs, some long wire, some clever code, and a car! I have this friend that has a speeding problem. So I built this device for my friend so...
