21st Century Learning and Teaching

In our previous blog post (Tutorial…), we were playing around with a LED MATRIX <===> First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Scrolling Text with 8×8 LED MATRIX  <===> and we will continue to use the LED MATRIX, but this time with a Wi-Fi connection. We will use the module “ESP8266” which you can purchase worldwide around as it is very popular and it costs ONLY 7.49 €.

Wire Library

This library allows you to communicate with I2C / TWI devices. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to the AREF pin and the additional one is on pins 20 and 21.

As a reference the table below shows where TWI pins are located on various Arduino boards.

As of Arduino 1.0, the library inherits from the Stream functions, making it consistent with other read/write libraries. Because of this, send() and receive() have been replaced with read() and write().

The Raspberry Pi Foundation has launched the Raspberry Pi 3 Model B+, offering a faster CPU and faster wireless throughput than its predecessor, the Raspberry Pi 3 Model B.

Raspberry Pi 3 Model B+ comes exactly two years after the launch of the Raspberry Pi 3 Model B and is in line with Raspberry Pi Foundation's two-year B+ 'evolution' upgrade.

In other words, the changes don't warrant calling it a Raspberry Pi 4, but there are noticeable improvements, including a faster processor, higher Wi-Fi speeds, and faster Ethernet.

Today, at Embedded Linux Conference 2018, Arduino announced the expansion of the number of architectures supported by its Arduino Create platform for the development of IoT applications. With this new release, Arduino Create users can manage and program a wide range of popular Linux® single-board computers like the AAEON® UP² board, Raspberry Pi® and BeagleBone® as if they were regular Arduino boards. Multiple Arduino programs can run simultaneously on a Linux-based board and interact and communicate with each other, leveraging the capabilities provided by the new Arduino Connector. Moreover, IoT devices can be managed and updated remotely, independently from where they are located.

To further simplify the user journey, Arduino has also developed a novel out-of-the-box experience for Raspberry Pi and BeagleBone boards, in addition to Intel®  SBCs, which enables anyone to set up a new device from scratch via the cloud without any previous knowledge by following an intuitive web-based wizard. Arduino plans to continue enriching and expanding the set of features of Arduino Create in the coming months.

Light guided rotating and moving plastic container. In previous Maker tutorials WE were using LEDs and vibration motors, WE will continue with it and adding some NEW components: a transistor and a LDR (Light-Dependent Resistor). WE will use ALSO AGAIN a plastic container, this time a transparent one so that persons could see…

The Mini BUG Robot In last blog post (tutorial) WE were practicing OUR soldering by creating "JOHNNY the ski-man", a bit "Electronics-Art" using electronics components. In the video below, which I created with the FREEWARE <===> Windows Movie Maker <===> WE see ALSO "The Mini BUG Robot" who gives "JOHNNY" a ride. It…

In this project we’ll show you how to make a WiFi enabled, portable Weather Station using an ESP8266. LINKS BELOW! The software, written by Daniel Eichhorn, uses the Wunderground API to pull weather data. It shows the date, time, current weather conditions, 4-day forecast and even moon phases.

The user interface features lovely typography and icons that makes really a clean layout. The 2.4” TFT Feather Wing combined with the Adafruit Feather HUZZAH ESP8266 make assembling this project incredibly easy. Full Tutorial, Files and Code: https://learn.adafruit.com/wifi-weath...

The new feature will allow Pi owners to write Arduino Sketches to interact with sensors, motors, electronic boards and other hardware attached to the Pi's GPIO pins.

Arduino Sketches can now be used to program the Raspberry Pi, marking a moving together of two of the biggest maker platforms.
The cloud-based Arduino Create platform is designed to simplify the creation of Internet of Things applications.
Want to use the $35 Raspberry Pi computer to build your own hardware but only ever used Arduino boards? Well you're in luck.

If you know how to write programs to control hardware using Arduino boards you can now use the same language to control hardware attached to the Pi, the co-founder of the Arduino Project Massimo Banzi announced yesterday.

Banzi revealed a new feature in the cloud-based Arduino Create service that will compile Arduino Sketches — programs typically used to interact with Arduino boards and attached hardware — into a form that can be run on a Raspberry Pi.

The feature will allow Pi owners to write Arduino Sketches to interact with sensors, motors, electronic boards and other hardware attached to the Pi's GPIO pins.

"The idea is there's a tonne of people that know how to use Arduino and they can take their knowledge and apply it to this," Banzi told the Embedded Linux Conference 2018 in Portland in the US.

Bastelplatine ist flotter und hat GBit-LAN
Der Raspberry Pi 3B+ hat schnellere ARM-Prozessorkerne, es gibt ac-WLAN für das 5-GHz-Frequenzband und Gigabit-Ethernet. Der Preis der Bastelplatine beträgt 40 US-Dollar.

Pünktlich zum Pi-Tag erscheint der Raspberry Pi 3B+ der Rasperry Pi Foundation. Die Bastelplatine folgt auf den Raspberry Pi 3B und hat trotz der vermeintlich kleinen Namensänderung mehr Neuerungen integriert, als die Bezeichnung Raspberry Pi 3B+ impliziert.

BEAUTIFUL AND CLEVER

The Monarch flashes its LEDs when its antennae touch. But it's also clever! It uses a clock source and shift register in a particular configuration in order to generate its patterns. Through it, one can learn about the basics of digital design, clocking, and randomness.

It is a third in a series of electronic 'bugs', the first is The Lady and the second is The Gent.
