In large houses or outside, the connection of the Wi-Fi router usually does not reach all corners. Even normal W-LAN repeaters are not as cheap as one would expect. An ESP8266 access point or Wi-Fi repeater, however, is! This can either amplify the Wi-Fi signal or serve as an access point via a LAN cable. […]

The Wio Terminal from Seeed Studio is a development device that is standalone or e.g. can be operated with the Raspberry Pi. It is possible to display simple data such as memory information, CPU usage, etc., or even to add a third screen to the Pi. In addition, the Wio Terminal brings among others also […]

The ESP8266 NodeMCU is a small microcontroller that has GPIOs and can connect to the Internet via WLAN. This and the low price make it very interesting compared to Arduinos, for example. In upcoming tutorials, we want to use the inexpensive ESP8266 modules to send data via a Wifi connection to the Raspberry Pi, which acts […]

Many of the sensors originally developed for the Arduino do not offer a digital interface and can only be read out analog. The problem is that the Raspberry Pi with its GPIOs cannot read out any analog signals, which is why you need an analog-digital converter (ADC) like the MCP3008. This means that up to […]

As already announced at some point, there will be additional tutorials on how to use an Arduino on the side of the Raspberry Pi. The Arduino is a small microcontroller, which is very cheap to have but allows many additional features to the Pi. In combination, the two offer even more options than the Raspberry […]

I have already described in a previous article how the Arduino works and which models exist. There are plenty of articles on the Arduino itself, but few in connection with the Raspberry Pi, but this combination offers many possibilities. Since I want to show more about the Arduino in conjunction with the Raspberry Pi, I […]
