At the beginning of 2021, Raspberry PI announced the new RP2040 microcontroller and the Raspberry Pi Pico module. This microcontroller is interesting for its characteristics in particular, the presence of two Arm Cortex-M0 + cores with a clock freque...
This article has the details of features and specifications of the Raspberry Pi 4 and has the comparison at some points with the previous versions for a better understanding.
The video post is about how I built a smart IR remote controller using a WEMOS D1 module to automate my new BLDC fan. In this video, I’ll walk you through the setup and integration process, enabling full control of the fan through my home...

You can show the location of a Thing on the TTN Coverage Map. And also a line to the LoRaWan gateway(s) it uses to communicate to TTN. Things that have a GPS on board, can send that info themselves. But an Arduino MKR WAN 1310 doesn't have that ...
A bit of Linux play. How to turn an active unstructured log file into structured data.image source: nightcafe
Like many programs, my The Things Network Gateway generates a verbose log file. A lot of information. Every so many (> 1000) lines, there...
I connected an Arduino MKR WAN 1310 to The Things Network (TTN). Then tested if the Arduino integrates with TTN MQTT service. Now I'm working with the Arduino's payload in Node-RED. This post is my log of the activity.

I connected an Arduino MKR WAN 1310 to The Things Network. And enabled both send and receive. This post is my log of the activity.
A few weeks ago, I bought a LoRaWan gateway. In this post, it helps to get and end-to-end trace. I have ...
I installed the software for the Elecrow LoRaWAN gateway (see Low-Cost LoRaWAN Gateways! ), and enabled the gateway on The Things Network (TTN). I used Raspberry OS bullseye 32-bit lite on a Raspberry Pi A+. I tested this on a B...
I saw in an e-mail an advert for LoRaWAN gateway modules, so I took a quick peek, and was surprised at how low-cost they had become. These can be used with any computer, such as a Raspberry Pi, to wirelessly monitor or control sensors ...
