After our robot has already learned to drive and to follow a line, we now want to let it be controlled remotely. For this, we will first use an infrared remote control and later possibly an Xbox 360 controller. In addition to controlling the driving ability, the modes (follow line, autopilot, etc.) should also be […]
After we have defined the basic functions for our Raspberry Pi robot in the first part, we now want to use them by letting it follow a drawn line. To do this, we attach two optical infrared sensors (Line Follower: TCRT5000) to the body of the robot. If the line is lost, it is automatically searched […]
In addition to being used as a GPS tracking system, the HMC5883L module can also be used to build a Raspberry Pi compass. This indicates the angle at which it is currently located. The HMC5883L compass module can be addressed via I2C, like many other sensors. Complete position and position systems can be built together with […]
In addition to many other interesting projects with the Pi, a self-made robot is a small highlight because it brings together many components. In the following parts, we will create a robot with many (independent) functions step by step. In the first part of the Raspberry Pi robot tutorials, we will assemble the kit and […]
Pretty much any hobby project can be implemented with the Raspberry Pi, but getting started is often not that easy, especially for children. Due to the low price, the Raspberry Pi comes without accessories, which is also a small hurdle. The CrowPi 2 is a Raspberry Pi laptop that tries to solve this problem: In […]
OpenHAB is an interface for many home automation devices. In addition, it is also possible to use it to control the music played. In this case: Spotify. As you already probably know, Spotify can be controlled remotely (e.g. from the app). We will take advantage of this and create our own Remote Raspberry Pi Spotify […]
One of the most popular projects besides home automation and robots is the Raspberry Pi weather station. This can be used in both indoor and outdoor circumstances and can be expanded as required. We either display the data from other devices via a web interface or use the Raspberry Pi touchscreen. In this tutorial, we […]
The assembly and a square LED matrix are shown since those modules are not supplied soldered together. A library for the MAX7219 IC for subsequent projects is also installed, which makes control with a Python script very easy.
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 […]
In the age of the Internet of Things, more and more devices are connected. This is also suitable for your own Raspberry Pi home automation. However, each device uses a different transmission protocol, which can make controlling them quite uncomfortable. Fortunately, there is a remedy for this: The Smart Home System OpenHAB offers many existing […]
One of the special features of the Raspberry Pi is the programmable input-output pins. These so-called GPIOs can easily be switched via a program, which we will go through in this tutorial. For this we will write a Python program, on the one hand, we record inputs and on the other hand, we switch the […]
