21st Century Learning and Teaching

RFID RC522 Tag-Card Reader with LCD1602-I2C - We were already playing around with LCD's in our previous tutorial <===> First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Super Starter Kit UNO R3 Project | LCD and Sensors Project <===> but there we used the SPI-Bus, meaning: connecting 12 wires (Potentiometer connections included...)!! With the I2C Bus we need ONLY to connect 4 wires!!

1.Vorwort zur Arduino Anleitung

Diese Anleitung soll als Grundlage zum Erlernen der Arduino-Plattform dienen. Sie soll Anfängern einen einfachen, interessanten und eng geleiteten Einstieg in die Arduino-Thematik geben. Die Anleitung orientiert sich dabei hauptsächlich an praxisorientierten Aufgaben mit einer theoretischen Einführung vorab. Diese sollte man vorher unbedingt lesen, um bei den späteren Praxisaufgaben nicht an Kleinigkeiten zu scheitern.

Diese Anleitung ist im Rahmen einer Unterrichtstätigkeit entstanden. Sie kann kostenlos zum Erlernen der Arduino-Plattform verwendet, jedoch nicht ohne Erlaubnis kopiert oder anderweitig verwendet werden. Die Anleitung wurde sorgfältig erstellt und wird kontinuierlich gepflegt, jedoch wird keine Garantie für die Richtigkeit und Vollständigkeit übernommen.

Für die praktischen Aufgaben sollte man mit einigen elektronischen Bauteilen versorgt sein. Auf dieser Internetseite können sie passende Arduino-Sets bestellen, die speziell auf diese Anleitung zugeschnitten sind.

Here is a quick and easy little robot that can be built and assembled in about half an hour with the right tools and parts.

I didn't invent it. I saw a video of a thing like this on YouTube and thought 'Hey, that looks fun, I'll build one.'

So I grabbed some servos out of my junk box, an old cellphone battery I had kept in the hope of finding something cool to do with it, an arduino pro 3.3v that I had bought on a whim because I needed to reach the quota for free delivery and went to work.

An hour or so later, here it was!

Let's start with the basic assembly.

Cut off the mounting arm that's opposite the side where the wires come out on one of the servos (This will be your back servo). The back servo points down and the other forward. You can use glu or cable ties to keep them together.

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...

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.

Maker-First Steps in Electronics-Soldering Learning.

When WE start with electronics on the beginning we can work with so-called “Breadboards“(see photo below please), but soon or later soldering will become a MUST and an habit! SO, the BEST WE can do is to GET some PracTICE with soldering; in this tutorial we will make a bit “Electronics-Art“.

Building a Variable Power Supply With Few Components In previous tutorial Maker-First Steps in Electronics, the basics WE got a bit the PracTICE of soldering and WE learned ALSO about schematics, resistors, LEDs, diodes and OHM's Law. WE used ALSO a 9 Volt battery as a power supply for our projects; BUT batteries are expensive (3,99 €)…

I purchased this Arduino LCD-Keypad shield from Amazon and it had terrible documentation. I made this video for anyone else looking for the pinout of this v1.0 board.

Download Data Sheet:

https://docs.google.com/file/d/0B4YAsbVrVvjlOG1oZURDNEdSWGc/edit

Some Sketches require the OLED_I2C Library, here you can download it as a ZIP-File and include it through the Arduino IDE:

1) Click on "Sketch"

2) Click on "Include Library"

3) Click on "Add ZIP.Library..."

Have FUN and enjoy Coding!

How to connect and program the Geekcreit 0.96 inch 4 pin white I2C OLED module with Arduino. OLED display based on a SSD1306 OLED driver IC.

In this tutorial a 0.96 inch monochrome OLED display from Geekcreit is connected or interfaced to an Arduino. Libraries are then installed and some example programs run which show how to use the display in an Arduino sketch.

The display connects to Arduino using only four wires – two for power and two for data, making the wiring very simple. The data connection is I2C (I²C, IIC or Inter-Integrated Circuit). This interface is sometimes called TWI (Two Wire Interface).

At the very lowest level, the Arduino Wire library is used to communicate with the display. Libraries are available that make it easy to start using the display right away to display text and graphics. These libraries are installed in this tutorial.

FriendlyElec has released a $35 rival to the Raspberry Pi 3 B+, outdoing the better-known board with 2GB of memory, Gigabit Ethernet, and a more powerful GPU.

The NanoPi K1 Plus follows FriendlyElec's Nano Pi K2, released last year with similar dimensions to the Raspberry Pi 3 for $40.

The NanoPi K1 Plus shares similar specs to the Nano Pi K2 and maintains the Raspberry Pi's form factor, but offers double the RAM, Gigabit Ethernet, and 4K video playback.

The device also has the same 40-pin GPIO pin-header as the Raspberry Pi 3, so it should work with Raspberry Pi accessories and housings.

Instead of the NanoPi K2's 1.5GHz Amlogic processor, FriendlyElec opted for an Allwinner H5 quad-core 64-bit Cortex A53 processor that runs at 1.4 GHz as well as a six-core Mali450 GPU. The Raspberry Pi 3 B+ uses a 1.4GHz Broadcom BCM2837B0, Cortex-A53 ArmV8 64-bit SoC.

The NanoPi K1 features three USB 2.0 ports, one microUSB 2.0 port for power, a microSD slot, while wireless support includes 802.11 b/g/n.

Didactic model of the "first transistor".In this project the models such as constructing a didactic model of the first transistor for which I made use of the materials that can be easily obtained, in addition to a little painting, the prototype / model I did on a scale a little larger than the original.

But from before, a bit of history.It all started at Bell Labs, where American physicists Jhon Bardeen, Walter Houser Brattain, and William Shockley conducted experiments and observations to try to create a solid-state amplifier, making use of the properties of semiconductor materials, thus replacing the Vacuum used at that time.The above image shows the first transistor created at Bell Labs in Murray Hill, New Jersey, United States in 1947.

Its inventors won the Nobel Prize in Physics in 1956 for "their research on semiconductors, and the discovery of the transistor effect." Now we continue with the instructions...
