21st Century Learning and Teaching

Well, I made some searches on the internet and I found the right answer on a forum about this error, which says that one should scan the I2C Address of the device and replace the “lcd.init();” by “lcd.begin (0x3F,16,2);” whereby “0x3F” is the I2C Address of my LCD1602/I2C module. I scanned to find out the I2C Addess with this sketch, please check here:

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:

Unpacking the Starter-Kit . Unpacking my NEW Arduino-UNO Starter Kit, which I ordered at Conrad (English version), looks GREAT, quality stuff and well documented! Feeling HAPPY like a kid who got something NEW to play with it! Click here for the Conrad German version. I just finished reading the included projects book: the project codes (Coding) don’t look that difficult; should be easy to learn. The book is very well documented, fool proof! Let the adventure begin!

Super Starter Kit UNO R3 Project From Elegoo. In one of my previous blog posts I used Arduino-UNO Starter Kit, which I ordered at Conrad (English version) and I wasn't really impressed by the manual, it didn't satisfy to my expectations and needs. SO, I was looking around to find some distributors for a BETTER version...…
