This beginner tutorial is about distance measurement with an ultrasonic sensor and the Arduino. With a simple circuit and some mathematics it is done quickly.
In this tutorial you will learn how to control a servo with the Arduino. As a first exercise we will control the servo to fixed, pre-defoined positions. After that we will develop a program that allows to enter the desired position via the serial monitor.
Often you want to establish a wireless connection to an Arduino. For example, you can remote control robots or transfer measurement data to a computer for further evaluation. In this tutorial I explain how you can build a wireless connection between an Arduino and another device with little effort.
Joysticks can be very handy for many applications like retro gaming, robot or robot-arm control, remote controlling cars or drones. But the best thing is: using a joystick with the Arduino is extremely easy!
In this tutorial you will learn how to use the motor shield L293 to control DC- and servo- motors with the Arduino. The L293 is a cheap and simple solution for applications which us several DC-motors and servos at the same time.
Communication between two Arduino (Nanos) via NRF24 WIFI modules.
This tutorial is about how to configure the Raspi so that you can develop your project easily and comfortably even without a desktop on the Raspi. To execute remote commands we will use SSH, Samba for simple file exchange.
This tutorial shows you how amazingly easy it is to take pictures and videos with the raspi camera and a little python code.
Two examples of communication based on the MQTT protocol: a simple chat tool for text messages and an automatic exchange of (image) files.
Wanna be able to talk to your computer? JARVIS it is a prototype for a command control by speech recognition which is based on a pre-trained artificial neural network. It is able to recognize and respond to spoken commands in real time.
Smart Gate is an ideal project to get started with Arduino. It is really simple, but contains all the essential components needed for more complex projects: you have to control a servo motor to open and close the gate, to query an ultrasonic sensor and to switch a red and a green led.
The goal of the project is to build a small but fully functional gripper arm for a robot. The arm used is the EezyRobot arm, the parts can be printed with a 3D printer. The focus of the project is the programming of the Arduino microcontroller that controls the arm.
The Arduino Smart Car is an ideal entry-level project that can be expanded at will to actually become smarter and smarter. The parts are cheap, the programming effort for the Arduino (programmed in C++) is manageable.
The "Falcon Not So Heavy" is an airworthy model of the Falcon Heavy rocket from SpaceX. The Falcon Heavy is a 1500 ton rocket, which uses a total of 28 engines to bring up to 64 tons in a low Earth orbit. What is really special about the Falcon Heavy, however, is that the three boosters of the rocket can be reused.
3D printing offers many new possibilities in building models, for example the construction of models that have never been offered commercially. I have decided to build models of rovers that have been to Mars or will go in the future (luckily there are not that many).
FlyRider is the fulfillment of a childhood dream: flying like a bird. FlyRider follows the idea to realize a manned drone with as little effort as possible. Which does not mean that it is easy... FlyRider will be a multicopter design capable of carrying a real person.
Is it possible to build a semi-autonomous "Mars" rover for less than € 750? That is exactly the idea behind the "Discount Mars Rover ". Instead of spending a lot of money on prefabricated hardware, the aim is only to use cheap materials and low cost electronics.
