MORE ABOUT Arduino

Released last October at the 2019 Maker Faire Rome, the new Arduino Pro IDE is based on Eclipse Theia.

Pixy2 is an artificial vision sensor for rapid recognition of moving shapes and colours. It follows objects at a rate of 60 images per second and has algorithms for recognition of shapes and colours. To better follow moving objects, it may be mounted (as an option) on a pan-tilt support, and control the vertical and horizontal movements itself.

From small DIY projects to large industrial applications – PLCs that work on an open source software base changed the way how tech professionals do their control and automation. They don’t fully lock you in to a specific vendor and enable you to customize the control and automation process of your specific application possible.

This is a submission from Distrelec on a free live webinar on IoT security in collaboration with the world’s leading open-source hardware and software manufacturers, Arduino. Sharing a wealth of industry knowledge, Gianluca Varisco (Chief Information Security Officer at Arduino) will provide a detailed understanding on why the future and success of IoT is in the “security of things”.

Creating a new sketch in the Arduino IDE makes the editor open a template containing skeletons for the functions setup and loop. What if you don't like this template? Can you edit it somehow? Yes, you can, and here is how.

This Arduino project, described in the November & December 2017 issue of Elektor is both useful and original in many respects. It is notable for the use of a component a bit out of the ordinary: a load cell. For electronics purposes, this is a simple variable resistance which measures the mechanical deformation to which it is subjected.

When you have to use the Arduino IDE on a public or university computer on which you are not allowed to install anything, you may not be allowed to install any board packages or libraries. Making the Arduino IDE portable solves this problem.

This glowing new bargraph thermometer from Elektor Labs is based on an Arduino Nano. It offers a beautiful graphical representation of ambient temperature using a Russian IN-9 tube and an illuminated scale with various RGB-controlled colours. The temperature scale in degrees Celsius as well as Fahrenheit extends from 10 °C to 30 °C / 50 °F to 85 °F. The circuit consists of a 5-to-150 V "voltage doubler" step-up converter, an IN-9 tube driver based on a low-voltage rail-to-rail opamp, two RGB LEDs and of course the Nano.

Take two DVD players, use one as a plotting platform moving forward and backward, and mount the other vertically on it to provide left and right displacements. Add a simple RC servo to it to move the tool up and down and away you go.

Suppose you want to measure a slowly-varying voltage from a sensor, or perhaps plot the discharge curve of a battery. Is it really necessary to sit there and note down a reading from the multimeter every so many seconds or minutes? It is less tedious and much more elegant to use this Arduino-based unit connected to your oscilloscope. Two questions motivated Kurt Schuster at the beginning of this project: ‘is my battery any good?’ and ‘is this charger charging my battery correctly?’
