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 […]
The Raspberry Pi Foundation has released a pure microcontroller at a super low price: the Raspberry Pi Pico. This differs from its “siblings” but is easier to program than seldom before. We can write our first small application using MicroPython and/or C++. In addition, the Pico comes with many GPIOs on board and even one […]
If you are looking for a swift, genuine, and versatile operating system for your Raspberry Pi, then you need to read this article thoroughly to find the best-suited OS for you. There are numerous operating systems available online that you can download for your Raspberry Pi, but it is certainly not easy to select an […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
