GPS is rapidly evolving from just being useful to being essential in our current world. Fortunately, there is an easy-to-configure, low-powered, Arduino-supported chip called UBLOX NEO-6M. All About GPS GPS (Global Positioning System) is a navigational system that is composed of 30+ satellites surrounding the earth. This satellite system in space is about 12,000 miles…
We’ve already tackled the schematic diagram of the famed Arduino UNO. It is now time to assemble it in your own breadboard! Here are the steps and some simple explanation on how to make an Arduino on a breadboard. Introduction What I love about Arduino is that it is so unselfish of its technology. It’s…
Circuit design always starts with a question of how to make things work. Engineers grab the nearest development boards, more often than not an Arduino, and rush to produce a working prototype. What comes next is the part that I’d like to share today. Optimization, specifically maximizing battery life. To paint you a picture, the…
I still can’t believe how much this board costs considering its features. If you’re tired of messy wires and would like to put on some sophistication on your DIY Arduino projects, stay tuned because today we’ll be doing wireless communications using the NRF24L01+ RF Transceiver Module. Overview The NRF24L01 RF GFSK Transceiver is just…
I really love the tutorial written by JP how to use ESP32 Deep Sleep. For the beginners who are not familiar with ESP-IDF and prefer to work with ArduinoIDE (or PlatformIO), I want to take JP’s lesson over to Arduino framework in a practical example. In my other tutorial LoRa Gateway I showed you how…
Get deeper into the Arduino craft by looking into a reference design. In here I will get into details with the basic arduino schematic diagram using one of their more popular development board, the Arduino UNO. So what is an Arduino? It can basically mean two things: One, it is an open-source hardware and software…
Part #2 – The LoRa gateway In my other post I made an introduction to Long Range (LoRa) communication. Now let us put this into a practical application. And to make it more interesting we will not only collect data from several sensor nodes, but as well send them to an IoT cloud service. This…
Part #1 – The sensor nodes In my other post I made an introduction to Long Range (LoRa) communication. Now let us put this into a practical application. And to make it more interesting we will use battery powered sensor nodes that can be left at positions where no power outlet is available. This part…
Usually we use WiFi, Bluetooth or GSM to connect our sensor devices with the world of IoT. But what if neither of that is available (or not affordable like GSM)?
Use an ESP32 to monitor temperature, humidity and eCO2 – then toss the data online!
