On August the 24th, the Deputy Editor-in-Chief of Make magazine Germany (Peter König) send me a mail. They are in the process of making a special issue about the ESP32-CAM, and they wanted to know if it is okay for me to use my graphical version of the ESP32-CAM, as also seen on my blog …
The upload procedure for ESP32 boards is a little different from a standard Arduino procedure. Most Arduino’s will automatically reset when a new program is being uploaded, and will automatically enter programming mode. On some ESP boards you have to manually enter programming mode, and on the bare-bones modules, you even have to reset them …
Track width is one of the most critical factors of any printed circuit board (PCB) design. Anyone who has a good knowledge of track design will at some point face the challenge of determining the correct track width. Inexperienced designers tend to use the standard gauge given in the PCB layout software. And this can …
When we think about IoT and home automation, we look at modular and compact devices, sensors, microcontrollers, etc. Recently, the ESP32 microcontrollers have gained traction in the electronic world, especially in the IoT field. This device has multiple features such as inbuilt Wi-Fi, Bluetooth modules, and sensors. The ESP32 microcontroller runs on a 3.3V voltage …
SeeedStudio is a China-based PCB Prototype (Printed Circuit Board), PCB Assembly, SMD Stencil and Flexible PCB Manufacturer. They ship to over 170 countries around the world and process over 2100 PCB orders per day. I’ve tried many other PCB manufacturing companies in the past, but I feel like SeeedStudio combines an excellent price and customer …
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 …
