A Lesson in LoRa Module P2P Standards (or the Lack Thereof)

I got a handful of LoRa modules from Reyax a while back, the RYLR896 model based on Semtech SX1276 chips. Instead of using an SPI interface they operate over UART using a small set of AT commands. This made them easier to work with since I didn't have to dig too deeply into a bunch of SPI registers and Semtech specs and they communicate between one another really well. My Espruino JS module for them is available here , which I've used in a few of my YouTube videos. And more recently I've written a MicroPython module for them here .   (A pair of Reyax RYLR896  modules) But, always being on the lookout for different boards and platforms I eventually ended up with a few Maduino LoRa boards. These are cool because they have an Arduino-compatible ATmega328 and the same Semtech LoRa chip (via an RFM95) both integrated on one board. They weren't compatible with Espruino or MicroPython though, and they used the SPI interface instead of AT commands so I knew I would need to lo...

DIY Solar Powered LoRa Repeater (with Arduino)

In today's video I be built a solar powered LoRa signal repeater to extend the range of my LoRa network. This can easily be used as the basis for a LoRa mesh network with a bit of extra code and additional repeaters. Even if you're not into LoRa networks all of the solar power hardware in this video can be used for any off-the-grid electronics projects or IoT nodes!  

ESP32-Cam Quickstart with Arduino Code

Learn how to add a camera to your Arduino projects the easy way using one of these cheap ESP32-Cam modules. Great for pet cams, home surveillance, time lapses, and computer vision applications.  

Intro to Arduino with LoRa

If you've ever wanted to get started using LoRa wireless communication in your Arduino projects this video is for you. It covers some popular LoRa module options, a brief introduction to the Arduino code needed to control them, and an explanation of the different ways to configure your LoRa modem to maximize range or data transfer rate along with visualizations of the LoRa packet transmissions. It's time to get wireless...

Arduino-friendly 240x320 LCD Display Tutorial (ILI9341)

Have you ever needed to add a UI to any of your embedded projects? For instance, maybe you want to display a sensor reading graph or build your own handheld gaming system. In this video I'll take a look at some cheap 240x320 color LCD display devices that you can add to almost any microcontroller or Single Board Computer project.

Concurrency on the Internet of Things (Arduino, MicroPython, Espruino)

In this presentation I talk about what concurrency actually is, why it matters for Internet of Things applications, and which platforms are best at handling it.
