Some weeks ago I got some Adafruit NeoPixel, a compact RGB LED module. Each LED module has a WS2812 chip that only needs three wires: power, ground and data. The data protocol is self-clocking, at a rate of 800KHz. The LED modules can be chained to build longer LED stripes. (For more details see the […]
I’ve been playing with the GPIO capabilities of the Raspberry Pi before using Python, which comes with easy GPIO access for the Raspberry Pi.
Java 8 for ARM
As I’m yet not very familiar with Python I got excited when Oracle accounced Java 8 for the ARM platform, so I downloaded the JDK […]
Do you remember the LCD display? I’ve connected it successfully to an Arduino lately, so when I got my Raspberry Pi some days ago it was just a matter of time to try connecting the two:
I followed the nice instructions […]
Although I’m mostly working with the “normal” digital input / output on the Arduino, it might be a good idea to play with the PWM output, too, just to have a basic knowledge about it if needed.
I’ll not go too much into detail about the theoretical background of PWM (highly suggesting you to read […]
Just some shameless self-promotion:
I recently uploaded my 3rd open-source project to SourceForge.net. It’s called jspinfo() and – for all of you who are familiar with PHP – it’s like phpinfo() but as a JSP file.
So, if you are a developer and you need some information about some common server settings, then […]
Earlier today I’ve been following the Arduino Tutorial for driving a 74HC595 shift register which turned out to work pretty well.
In short, a shift register is an electronical component that can be controlled using 3 wires to change the output of 8 pins, or even more when two or more shift registers […]
