During one of my many AliExpress shopping sprees, I recently found a cute little 1.3" High Resolution 240x240 pixel IPS TFT display. Till now, I only used monochrome 128x64 OLED displays, so this little toy sparked my interest. Using it would be a matter of connecting it to the SPI bus … or so I thought!
It has been almost a year since I started the activity board project. So it is time to wrap it up. As said in the last activity board blog post, the only thing left to do was to finish the interface …
If you you are a tinkerer that likes to play around with Arduino’s and electronics, you’ve probably played around with a 4 pin I2C OLED display more than once. To step up my game, I thought it would be fun to give myself a little challenge and try out a barebone OLED screen without the convenient breakout board.
As most of the Arduino tinkering makers, I have some NeoPixels LEDs in my drawers. Especially the 8x8 NeoMatrix is a beautiful piece of illumination. But till now, I didn’t have any good use for it yet. Time to make it a bit more useful!
As told a few weeks ago I was quite successful in blowing up my Adafruit Neopixel NeoMatix. Not once, but twice. And although the bypass was a nice workaround for the time being, I wanted a more permanent fix for my beloved LEDs.
While working on one of my Arduino projects, I was in the need for a simple wrapper for communication with the Adafruit Bluefruit LE nRF8001 Breakout.Since I was unable to find one (especially one that was Swift-ready) I wrote a Swift-wrapper myself. It is based on a Bluefruit LE Connect.It has all the basic needs for basic two way communication and is easy to implement.Check out nRF8001-Swift on GitHub!
When I still lived at my parents, I knew the way to my father’s ‘secret’ electronic ingredients stash. It was right across the hall. Now, although I like the fact of having my own house, it’s somewhat inconvenient to drive 30 minutes before I can loot some of his stuff.
As a side effect of my electronics hobby I developed the addiction of online parts shopping. From time to time I browse the well known electronics shops looking for parts I don’t need. One of the brands with the highest wanna have factor is Adafruit. Adafruit has a wide verity of neat little components that are accompanied with clear documentation and nice code samples. One of my recent Adafruit purchases is an 0.96" monochrome 128x64 pixel OLED display. During my purchase, I had no idea what to use it for … until I got my hands on it!
