How to use the ESP32 Cam with PlatformIO? In this mini-project, you will learn the basic essentials, and we will make the built-in flash LED blink via code!

How can you flash your ESP32 Cam without a USB port? You will need what is known as an FTDI. What this is and how to connect such an FTDI to the ESP32 Cam, we will take a closer look at.

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.

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.

QUOTEFRAME, this is a DIY digital sayings calendar. Runs on battery, has Wi-Fi to edit the sayings and has an extremely high WAF value. It also makes a great gift! I’ll show you what you can do with it and how I put it together! Today we build something that can be used as a gift for all who like

Power ESP with batteries! Plus: the best battery holder ever! Which batteries and accumulators are best suited to supply ESPs or similar microcontrollers with power? We’ll clarify that in this article. I’ll also show you one of the best ways to mount batteries in your project case and how to create a tidy power supply: with the Flex Battery Holder

Screws are sometimes annoying. Because the right screw is often no longer available in sufficient quantity. Besides, you have to turn them forever. And especially in the prototype phase you have to remove your board with the microcontroller more often. I have a great thing for you, I call the whole thing: PCB Clips. PCB stands for Printed Circuit Board.

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
