In this tutorial, we are going to explore the pre-installed AT firmware inside the ESP8266. The AT Firmware The AT firmware is a pre-installed software…

Quite often, we want to place our sensors at locations where we have no access to a power outlet. The obvious solution is to add some solar panels and batteries to your project to make it run 24h / 7 days a week without the need to recharge it.

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…

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…

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,…

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…

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…

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…

Part #2 – The LoRa gateway In my other post I made an introduction to Long Range (LoRa) communication. Now let us put this into…
