After we are able to record individual images with (USB) cameras / webcams, we also want to view live pictures. This can either take place on the smartphone or on a PC fom outside of the home network. For this purpose, we configure the Livestream of the Raspberry Pi security camera. The great thing is […]
Node.JS is a server platform that uses JavaScript. Originally developed for the Google Chrome browser, it is very resource-efficient, which makes the use of a Raspberry Pi Node.JS web server interesting. In addition to the advantages of asynchronous applications, Node.JS offers a very simple but powerful method to install and use different plugins or libraries, […]
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 […]
LCD character displays are a simple and a cost-effective way to display a text. Thanks to the HD44780 controller, the control of the modules has become very simple. However, one must occupy many GPIOs for it. An alternative is the I2C data bus, which means that only two GPIOs are used. In this tutorial a […]
In addition to the control of the Raspberry Pi via infrared remote controls, 433 Mhz transmitter, messengers and many more, also a wireless Xbox 360 controller can be read from the Raspberry Pi. This allows the gamepad to be used as an external mouse (in desktop mode) or in scripts and thus the GPIOs can […]
In an increasing number of cities, the trend is towards organic or even self-grown fruits and vegetables. Perhaps a deterrent cause is the time spent on plant care. Therefore, this project involves the creation of an automated Raspberry Pi greenhouse, which reduces the work to a minimum. By automatic watering, airing and exposure, only harvesting must […]
One of the many Raspberry Pi projects is the lighting of rooms or objects. LED strips are particularly suitable for this purpose, because many individual LEDs are aligned and each individual LED can display all RGB colors. Thus, some projects such as room lighting, Ambilight or e.g. a Christmas tree lighting can be realized. The […]
Not only in Hollywood films, fingerprint readers are seen more and more frequently. Such modules are often installed in home surveillance systems and are used for the simple but secure verification of persons. With such a Raspberry Pi Fingerprint Sensor you can also implement some other projects, such as secured locks. One of the advantages […]
Not only with fitness watches, but also with the Raspberry Pi it is possible to measure pulse / heart rates. With a small module – the Raspberry Pi pulse sensor – you can easily measure your own pulse and thus monitor permanently your health condition. This sensor can also be used in mobile Raspberry Pi […]
Sensors are necessary to detect the components of the air. These are used e.g. in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi is shown. Thus, e.g. smoke detectors or air […]
Google Chrome is one of the fastest and most widely used web browsers for desktop computers. Due to some statistics Chrome is used on more than half of all PC’s of the world. Since it is a opensource project, you can get also Chrome for Raspberry Pi’s. In this tutorial I will show how to […]
