50 of the most important Raspberry Pi Sensors and Components

Felix - 22. January 2016

One of the many advantages of the Raspberry Pi is that it is possible to connect almost all standard Arduino and Raspberry Pi sensors and components to the dhtvarious GPIOs. Moreover you can evaluate and / or process the values with programs and other software. This accessory can be used in projects such as Smart […]

Raspberry Pi: Set Up USB Boot Using a Stick or SSD Hard Drive

Felix - 24. January 2021

The Raspberry Pi usually needs a micro SD card on which the operating system is located. The disadvantage is, on the one hand, that SD cards break faster and, on the other hand, they usually have less storage space than a hard drive. In this tutorial, we will take a closer look at the Raspberry […]

How to Build Your Own Raspberry Pi Android Box

Felix - 2. January 2021

Making an Android TV box out of a Raspberry Pi 4 is quite easy and straight forward practice. Not only is it an affordable alternative, but it is a fun experiment to try that save you a lot of bucks in the process. When it comes to experimenting with the Raspberry Pi, the sky is […]

ESP8266 Access Point: Build a Cheap Wi-Fi Repeater Yourself

Felix - 13. December 2020

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. […]

Display Raspberry Pi Data on the Wio Terminal LCD Screen

Felix - 10. December 2020

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 […]

Remote Control of Raspberry Pi Robots with an Xbox 360 Controller (Part 6)

Felix - 24. November 2020

In this part, we want to control the robot remotely with an Xbox 360 controller. Compared to the infrared remote control, the controller has the advantage that it has two joysticks, which are ideal for controlling. In addition, with the second joystick, we can e.g. rotate a camera and the buttons can also be assigned […]

Let Raspberry Pi Robots Follow Their Own Voice (Part 5)

Felix - 24. November 2020

As a further feature, we now want our little robot to follow the sound of our voice. If the mode is activated, the robot should automatically navigate in the direction from which the call was made. There are also small analog sound detection sensors, which are read out via an MCP3008 ADC converter and then […]

Raspberry Pi Robot: Avoiding Obstacles Automatically (Part 4)

Felix - 21. October 2020

Our robot can now do a lot and can be controlled remotely. However, we also want to create an autopilot mode so that the Raspberry Pi robot can find its way independently. Cleaning robots etc. use comparable methods to avoid getting stuck at an obstacle. We use a servo motor and an ultrasonic sensor with […]

Control Raspberry Pi Robots via Infrared Remote Control (Part 3)

Felix - 21. October 2020

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 […]

Programming Raspberry Pi Robot: Making it Follow the Lines (Part 2)

Felix - 14. October 2020

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 […]

Build your own Raspberry Pi Compass (HMC5883L)

Felix - 11. October 2020

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 […]

Raspberry Pi Robot Kit – Assembly (Part 1)

Felix - 9. August 2020

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 […]
