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

While developing the ESP – HomeKit blinds, it became clear that stronger motors are needed. In this blog, we look at a DC motor controller in which the speed and direction of rotation must be able to be controlled. We are also looking at a controller for controlling a small electric motor via a PWM

Zener diodes are a special type of semiconductor diode devices that allow current to flow in only one direction and also allow current to flow in the opposite direction, but only when exposed to sufficient voltage. And while that sounds a bit esoteric, they’re actually some of the most useful components to ever cross an
Since Espressif Systems arrived in our collective consciousness, they have expanded their range from the ESP8266 to the ESP32, and going beyond the original WROOM and WROVER modules to a range of further ESP32 products. There’s a single-core variant and one that packs a RISC-V core in place of the Tensilica one, and now they’ve
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.
