The conditional… or “IF” statement Programs that count really fast or create MADLIBs are a ton of fun, but part of encoding knowledge is the ability to make decisions in code. To do that we need something that will allow the code to take two different paths… the “if” statement. The if statement checks a value… Continue reading Lessons on PI – Lesson 3 (cont.): A little programming…
The Sense Hat What’s a hat? Hats are the term that the Raspberry PI community uses to identify bits of hardware that are made to plug into the Raspberry Pi’s GPIOs (General Purpose IO) – that row of pins along one side of your pi. There are lots of these out there to make interacting with… Continue reading Lessons on PI – Lesson 4: The Sense Hat (and a little VIM)
On the Shoulders of Giants That phrase, “On the shoulders of giants”, has come to mean, “discovering truth by building on previous discoveries” which just about sums up all of computer science. That idea, is the reason Computers are moving so fast! When you can reuse the work being done by hundreds of thousands of people… Continue reading Lessons on PI – Lesson 2: On the shoulders of giants (apt-get, and git)
Make has a write-up on wand-control with a simple reflective wand. But… I just worked through it… its *way* broken. The git pull brings down the source with improper tabs and spaces. Also, its specific to python 2, as the print statements all have to be replaced. For now – turn back. Check it… Continue reading [BROKEN]Turn on a lamp with a gesture – IR Cam Image Processing!
Digital Logger’s IOT Logic Outlets In my previous two articles – we show two ways the Raspberry Pi can control power through Wifi: Raspberry PI for controlling TP-Link POWER Raspberry PI for Controlling Wemo Power These assume wifi-enabled outlets, which are great, but there are some cases where you really want the Raspberry PI to… Continue reading Raspberry PI Controlling Power through GPIO (no wifi needed)
MagPi Issue #53 This issue of the MagPi magazine has a great set of intro-to-programming articles that are short and sweet. To boot these folks have made this magazine available for Download. Its a tremendous resource. When teaching kids, having something that gets it done fast is important, and they’ve done a great job with… Continue reading MagPi Issue #53 is Fantastic for an Intro To Python Programming!
