Raspberry PI 2 – Python controlled circuits Button & LED experiments

So the last set of experiments definitely piqued my interest in the Raspberry PI platform and its capabilities to measure, control and otherwise interact with the physical world. In reality though, all I’ve done is play with some cheap hobbyist parts that could be picked up at any electronics shop. Still circling around the true capabilities of the PI, I realize I now need to connect the hardware capabilities to the software for creating a proper controller or event-driven system. Afterall, the hardware is where the “Things” aspect of the “Internet of Things” comes in to play and the software is what potentially reaches out to the “Internet” to connect multiple distributed devices or call out to cloud services for message relay between systems, analytics or additional intelligence.
As with the last article I sifted through the web resources out there to try to find the most relevan ones. The following videos show you how to extend the basic Breadboard/Circuit knowledge with the use of logic gates to do “code-on-chip” types of behaviors where your board/circuit can add a bit more intelligence to its basic input/output capabilities, how to safely extend the basic components with real-world sensors, and how to connect directly to the Raspberry PI as a power source via GPIO ribbon cable to control physical electronics experiments with code:

BC$ = Behavior, Content, Money
The goal of the BC$ project is to raise awareness and make changes with respect to the three pillars of information freedom - Behavior (pursuit of interests and passions), Content (sharing/exchanging ideas in various formats), Money (fairness and accessibility) - bringing to light the fact that:
1. We regularly hand over our browser histories, search histories and daily online activities to companies that want our money, or, to benefit from our use of their services with lucrative ad deals or sales of personal information.
2. We create and/or consume interesting content on their services, but we aren't adequately rewarded for our creative efforts or loyalty.
3. We pay money to be connected online (and possibly also over mobile), yet we lose both time and money by allowing companies to market to us with unsolicited advertisements, irrelevant product offers and unfairly structured service pricing plans.
