21st Century Learning and Teaching

SO, you are a retired EDUcator, TEACHer, Instructor, LEHRENDER: WHAT to do NOW?!! Well, that was the question I was asking myself when I became retired in 2014. As I did innovation in Modern-EDUcation in my country Luxembourg, there was NO WAY to give that up, BTW! SO, years before my retirement I…

Avec les nouveaux modèles d’enseignement, tous les équilibres, tous les codes sont remis en cause. Au sens strict du terme, il n’y a plus d’enseignant, pas de cours, pas de programme, rien que des cas concrets à résoudre en trouvant soi-même la solution ou en s’associant à d’autres élèves. Cette pédagogie met l’accent sur le comportement, les capacités à travailler à plusieurs et à apprendre très vite en autonomie.

Pour Romain Martin, vice-recteur pour les affaires académiques de l’Université du Luxembourg, «la principale erreur consiste à se focaliser sur les technologies elles-mêmes. Il ne faut pas simplement regarder l’outil, mais comment ces outils sont utilisés.» Une désacralisation des technologies pourtant au cœur des enjeux, au profit d’une démarche pédagogique nouvelle. La tendance est ainsi à l’«adaptive learning».

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!!

First Steps with the NodeMCU ESP8266 Wi-Fi Module. In our previous tutorials we were using already the NodeMCU ESP8266 Wi-Fi Module and we discussed about "Security", "Cyber-Security" issues while using "IoT", "Internet of Things" and the importance that the router MUST be protected by a NEW password and NOT ALLOW to let connect any…

SO, after that one has becoming a little bit familiar with all that new stuff one has lived already some experience and one is asking if there aren’t any helping tools and devices to make life much easier… YES, and there are some very interesting prototype shields, board holders and breadboard jumper in different lengths…

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 €.

How-To transform an LCD1602 SPI Sketch to an LCD1602 I2C Sketch We were already playing around, as seen on my tutorials below, with the Temperature/Humidity sensors DHT11, DHT22 and LCD1602, without I2C possibility. There were a lot of cables to connect, we will try out this time to use a LCD with I2C bus connection as it…

image2cpp is a simple tool to change images into byte arrays to use with (monochrome) displays suchs as OLEDs, like those from Adafruit or Sparkfun.

While searching for a way to generate these arrays, I mostly found links to a piece of Windows software. Both the flakey results and the hassle of having to boot a virtual machine just to convert an image lead to me writing this pure html + javascript solution.

Alternatively you can also enter a byte array as input to turn it back into an image. This might be useful for debugging, or when you want to write the byte array yourself. I don't know.

Running the tool

You don't need any special dependencies / internet connection; all the necessary parts sit in a single .html file. So just open this index.html page in a (recent) browser to run the tool.

Or you can use the online version at:
