In this post, I like to show, how to control a tiny servo motor like the SG90 with an Arduino UNO. Required components for circuit To rebuild the circuit, you need: Types of servo motors At the market, you can find some different types of servo motors. The main different is the weight and power…
Arduino Lesson #2 – LED flashing, traffic light
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…
Seeed Studio XIAO RP2040 – a dwarf with great performance
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…
Arduino Lesson #1 – setup & install Arduino IDE
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…
Presentation of the multifunctional shields for the Arduino UNO R3
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…
Is the Raspberry Pi Pico an alternative to the Arduino Nano?
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…
Arduino Lesson #109: measure voltage with the Arduino
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…
Arduino UNO – Button debouncing
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…
