I wanted to see if I could make a more realistic (LED) candle that you can buy in all kind of stores or on the internet. My idea was to use NeoPixels because I can control each pixel in every colour I want. But first I googled to see if someone has done it before, …
Not all European legislation for the standardization of USB-C for mobile devices, but also the switch of all kinds of electronics to USB-C will ensure that USB-C will become the standard. Look, but since the already well-known boards Arduino, Raspberry Pi, wemos boards, etc. have all already replaced the Micro-mini-USB ports with the USB-C port …
The Wemos ESP32-S2 is a small Wi-Fi module based on the ESP32-S2FN4R2. The S2 is a new version of the well-known Wemos D1 Mini. The biggest update to the S2 is about twice as many I/O pins in the same form factor. This means that most shields intended for the Wemos D1 Mini can also …

In this blog, we will discuss how to use the ESP32 touch sensors and how to use the esp32 touch sensors as a push button without having to connect an external push button. The ESP32 chip offers ten touch sensors. These touch sensors are built-in with ESP32 chip and are capacitive type. These touch sensors …
In my previous blog I set up a Raspberry Pi with Screenly OSE a free Digital Signage / Narrowcasting package. Although the software package works out of the box. There are still a few things that can be a problem. So here some troubleshooting items. Display rotation The first troubleshooting item is the display rotation. …
