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, …
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 …
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 this post, we’ll be taking a closer look at the ESP32-S2 hardware, and more specifically, the ESP32-S2 Mini pinout. The ESP32-S2 is based on the Xtensa® single-core 32-bit LX7 microprocessor, up to 240 MHz. The ESP32-S2 pinout consists of 43 × programmable GPIO’s pins, 2 × 12-bit SAR ADCs, up to 20 channels. The …
A thermocouple is a device for measuring temperature. It comprises two dissimilar metallic wires joined together to form a junction. When the junction is heated or cooled, a small voltage is generated in the electrical circuit of the thermocouple which can be measured, and this corresponds to temperature. Basics of Thermocouples A thermocouple consists of …
In this post, we’ll be taking a closer look at the Arduino® Nano hardware, and more specifically, the Arduino® Nano pinout. Arduino® Nano is based on the ATmega328 by Atmel. The Arduino® Nano pinout consists of 14 digital pins, 6 analogue inputs, USB connection and ICSP header. The versatility of the pinout provides many different …
As you are used to, I always illustrate my projects with a scheme made in Fritzing. The standard components are usually present in the default software. But often enough there are components not present. I then make these components myself. Because I have added a whole series again, I wanted to share my own new library, and …
The ESP32 comes with 2 Xtensa 32-bit LX6 microprocessors. So, it is dual core. When we run code on the Arduino app, by default, it runs on core 1. In this blog we’ll show you how to run code on the ESP32 second core by creating tasks. You can run pieces of code simultaneously on both cores, and …
If you’ve worked on electronic projects in the past, you’ve probably heard of breadboards before, and maybe even used them. But what does ‘breadboard’ mean? Breadboards can be a little confusing at first if you don’t understand the logic behind them – which is exactly why we came up with this blog to get you …
