Like a sunflower, this project stretches its bloom (solar panel) towards the sun. A laser-cut wooden frame with a bit of technology and you have a project that will excite not just children. The model can be found on the „quick“ Ali-Express under the term "Arduino Intelligent Solar Tracking" for around €25-50. After a quick search on the internet, I found...

This add-on board has an L298P motor driver on board. This allows two DC motors to be operated with up to 2A. In addition, the board also has a buzzer and some connections that have been brought out. See also the diagram in the next chapter. I will keep the test very short and only [mention] the buzzer and…

Board for controlling up to 16 servos via the I2C bus. It is recommended to use an external power source, as a large amount of current is required when the servos are operating simultaneously. Facts Connection I2C Bus of the Arduino Board Arduino Uno GND GND OE Not connected SCL A5 SDA A4 VCC +5V V+ Vin Connection I2C...

I had a joystick, an Arduino, and a pan-tilt unit lying around, and I thought I could combine them. See what came of it. Facts This is what I needed: Analogue joystick with two axes Ardurino Uno or similar Pan-tilt with two servo motors Motor control board V1 (practical but not necessary) A few pin header cables Socket...

Here, the assembly and commissioning of the cheap Pan/Tilt kit from AliExpress is described. Pan/Tilt is a platform that can be swiveled in two or more directions using two servos or motors. These are mostly used for cameras but are also very popular in the robotics field. Facts The following components are used for the test…

A linear servo is controlled in exactly the same way as a rotary servo, only that it performs its movement linearly along an axis. A small slider is moved along a screw. The position is determined via a variable resistor. The resistance changes depending on the position of the slider. Positioning is done via the signal cable. Here a …
Continue reading "Linearer Mini Servo"A new kit from AliExpress has prompted me to build a remote-controlled vehicle. The kit consists of an Arduino, an expansion board, and a PS2 controller with receiver. Components The chassis of the vehicle is formed by a kit from AliExpress LINK. This kit contains an acrylic platform with two motors, wheels, and some accessories. For control, I am using...

Controlling a servo with the Raspberry Pi 3. This is about the basic technique; the application could be, for example, a mobile robot. The servo is to be controlled via software PWM in order to keep the hardware PWMs free for other functions. Additionally, the servo should not be controlled via integer values as is usual...

Since I prefer to program in Java, I use the Pi4J library to control the GPIOs on the Raspberry Pi 2 and 3. I will not go into detail about the installation of the library, as this has already been exhaustively described on the following web pages. http://pi4j.com/install.html http://pi4j.com/utility/pi4j.html http://www.forum-raspberrypi.de/Thread-tutorial-ansteuerung-der-gpio-ports-mit-pi4j It is also important to know that Pi4J builds on the wiringPI library…
