In this new post, I like to show how to flash a LED at Arduino, and later I would like to show a small traffic light. In my last post Arduino Lesson #1 – setup & install Arduino IDE I have shown you how to setup and install the required tool Arduino IDE 2.0. If…
In this article I would like to introduce you to the small microcontroller Seeed Studio XIAO RP2040. I received this small microcontroller from Seeed Studio free of charge for this review.Since I wanted to order it anyway, it was a cheap way for me to get it. Purchase of a Seeed Studio XIAO RP2040 You…
In this post, I want to show you how to setup the Arduino IDE 2.0 on your computer and install the Arduino UNO microcontroller. Requirements for Arduino IDE You can download and unzip the Arduino IDE for Microsoft Windows, Linux and macOS. If you want to run this at Linux, you need some grants to…
In this post, I like to show a presentation of the multifunctional shields for the Arduino UNO R3. What is a multifunctional Shield? In the past, I have already presented some, but on my German section of the blog. This blog post will give you a first overview of the most common multifunctional shields. The…
In this article, I would like to answer the question “Is the Raspberry Pi Pico an alternative to the Arduino Nano?” This is not from me out of the air, but I have found on some sites so or so similar. Since I have already programmed some examples with the Raspberry Pi Pico and know…
In this post, I want to show how to measure the voltage up to 5V with an Arduino. Review In the article Arduino Lektion 4: LED mit Fotowiderstand I showed how to read the value of a photoresistor and “visualize” it via a light emitting diode. What we actually did is to measure the voltage…
If you build a pushbutton into your circuit, sooner or later you will encounter that it sends a signal more than once. This behavior is called “bouncing”. In the tutorial Arduino Lektion 33: Taster mit Pull Down Widerstand I already explained how to build a small circuit with a push button and a pull down…
In this tutorial, I want to show you how to set up and run the ESP32-CAM with a small example. Buy an ESP32-CAM The ESP32-CAM for this tutorial I bought via ebay.de for just under €8 incl. shipping costs. You can get this microcontroller at aliexpress.com or also banggood.com for a much cheaper price, but…
