Arduino, ESP32, 3D-Print, Neopixel & Co. – DIY Tutorials for Maker

Learn how to filter out your sensitive data like passwords, api keys etc. in your source code BEFORE pushing it to Git – and how to re-replace it automatically with your credentials again when pulling from Git!

The Art of Crimping! Here I show you step by step how to make your own jumper cables for Arduino, ESP32 and Co. – with a suitable crimping tool and some stranded wire you already have the most important materials.

Today I will show you all the different ways you can power up your Arduino, ESP32 or ESP8266 – which ports and pins can be used and what to take care of. Then I will show you two power supply setups if you need a little bit more amperes.

This guide gives you ALL the basics you ever need to start tinkering with 5 Volt LED Stripes like Neopixel, WS2812B & Co. and you beloved microcontroller like Arduino, ESP32 or ESP8266.

The Arduino development environment can do nothing, and that’s a good thing. Because this development environment was meant to keep the entry barrier into microcontroller programming as simple as possible and not to overwhelm the newbie with too many functions. I admit, I am a professional developer. And I am missing some features in the Arduino development environment that make

The Arduino can’t do anything and is way too expensive! What my favorite alternative is and why we still have to love the Arduino, I tell you in this article. I also show how to load a program to an Arduino UNO and to an ESP32 in the Arduino IDE. If I claim that the Arduino can do nothing, then this
