I had bought the hardware in October 2018 and only created a heading for this post. After Siegfried pointed out a problem, I was only too happy to finally fill this post with content and bring the project to completion. After three months of putting it off, I have this...

I ordered an Arduino Nano 33 BLE Sense Rev2 from Christkind, but I received a Nano 33 BLE. Well, „man“ takes what „man“ gets ;) . No, I'm not going to gender-neutralise this here because it would distort the facts. Before I wander off any further, I've had the thing unpacked in its box since the year before last...

In a shopping frenzy, I couldn't resist and ordered the new power pack from Arduino. The 33 IoT is in the form factor of the Nano but has Wi-Fi. It also has an integrated IMU with which acceleration and spatial orientation can be determined. More about this amazing board in the following sections. …

Is it possible to capture inputs on the serial port via interrupt? The answer is probably more yes-and-no, it is possible to use the Serial Event function. This is executed after every loop, but does not interrupt it. Purpose User input via terminal Communication with other devices via the serial port Necessary libraries None Program There is in the Arduino GUI…

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…

I bought these LoRa boards some time ago as a double pack and forgot about them in a drawer. With more and more reports about LoRa (Long Range Radio) appearing, I wanted to try it out as well. I have documented my attempts here. There is now a version 2 of the board. Version 2 also has…

An ESP32, a display, what more could you want. This is how the LilyGo ESP32 OLED board introduces itself, or something similar. It's relatively short and just about fits on a breadboard with a row to spare on each side. Facts General Description Value Processor ESP32 Flash [MB] 16 USB CP2102 Display SSD1306 Lipo Connector [mm] JST 2x ...

The Arduino Nano is one of the smallest of its kind, but no less powerful. It features an ATmega328 controller from Atmel, and the best part is that it fits on a breadboard. It has 30 connection pins, 15 on each side. For its operating voltage, it requires 7-20 Volts via Vin. However, it can also be powered directly with 5V. Here...
