This tutorial is about a simple Traffic Light Circuit using the programmable GPIO Pins via Python. In the next tutorial, we will extend the circuit by a few functions (including an Input).
In this tutorial, I want to show you how to set up and use a small infrared light barrier, which gives a signal as soon as the light barrier is interrupted. By traversing both photocells one behind the other, the speed can be measured.
Who has his Raspberry Pi running as a Server, etc., will quickly realize that the little giant can become very hot. To a certain extent, one can surely ignore this, but if the Pi is running day and night, you should pay attention to the temperature (especially in a housing). Since I also had this […]
MQTT is a protocol that specifically sends data from devices of the Internet of Things and is supported by most microcontrollers and systems. To use Raspberry Pi MQTT communication, not much is needed, which is why this type of transmission is very interesting. In addition, it is really easy to use. In this tutorial, we […]
If you are looking for RGB LED strips, you will probably come across the WS2812 or the WS2801. These two LED strips are very different, but both can be controlled with the Raspberry Pi. After using the latter in a previous tutorial and using it in our Ambilight, this tutorial is about using the Raspberry […]
As hardly any scales work analogously, it is of course also possible to measure weights with a digital Raspberry Pi scale. This can be used in various applications as the weight value ranges which can be measured are also almost unlimited. Only a sensor and a load cell are required, which are available for different […]
