We’ve recently received a new product from MonksMakes (http://www.monkmakes.com/) called a Raspberry Squid.
These are RGB LEDs which have built in current limiting resistors, and header sockets that will fit straight onto the GPIO pins of a Raspberry Pi. There’s also a push button which, like the LED, has a built in protection resistor and header sockets to fit straight onto the GPIO pins.
We think these are a brilliant idea, as for a quick maker project it saves all the usual fiddling around with breadboards or soldering. The image below shows how easy they are to use:-
The Squids are also easy to use in terms of programming, as it’s simply a matter of referencing the correct GPIO pins from whichever programming language to choose to make use of. The http://www.monkmakes.com/ web site also contains a link to a Python library and some example Python programs that you can use with the Squids.
If you’re feeling adventurous, there are also instructions for how to make your own Raspberry Squids.
