Another add-on board for the Arduino Uno and compatibles. It is equipped with a u-blox GPS chip. Additionally, it has a slot for a µSD card, making it suitable as a GPS logger. The current version 1.0 has already been superseded by version 2. The new version is due to the current chip shortage…

I am always surprised that there are still a few readers here on the blog. Recently, Siegfried messaged me and said he wanted to display some bars on a Cristal LCD display, and if I had ever done it before. The answer was no, but that was set to change soon. Facts Parts list Arduino Uno Arduino LCD…

A friend was recently complaining to me. He's now working from home and is worried that his employer is tracking his computer data. Since the computer goes into standby mode after a few minutes, he came up with the idea of constantly moving the mouse to prevent this. His wireless mouse even reaches the toilet, he said…

These can simply exist as a name, as shown below: or they can be assigned a value. The pre-processor then inserts the corresponding value at every point where the constant ‘name’ is used. Expressions are also possible: Whether a …

Like a sunflower, this project stretches its bloom (solar panel) towards the sun. A laser-cut wooden frame with a bit of technology and you have a project that will excite not just children. The model can be found on the „quick“ Ali-Express under the term "Arduino Intelligent Solar Tracking" for around €25-50. After a quick search on the internet, I found...

I've once again found a small board with an ESP on the fast Ali. This time, however, it's an ESP8285, which apparently only differs from the ESP8266 in its internal 1MB flash memory. This board costs just under 4 Euros, has no USB port, and must be programmed with applications using a programmer. On the other hand, it has an IR receiver and an IR transmitter and is quite small. The ports are not brought out via pins, but it seems quite possible to solder cables to the ESP board. You'll find the data as always in the following chapters.

I've had the Zumo for a few years now and just rediscovered it in a box. So I thought it would be nice to write a bit about it. The Zumo is a small mobile platform onto which you can directly plug an Arduino Uno or Leonardo. It has two motors and a few sensors…
