We also saw it is possible to control the reading and execution of circuits using programming code rather than through rewiring of physical electronics. In some ways, then, the integrated circuit begins to place these components into a “black box.” But the individual electronics are still there, all the same. In this way, all that is apparent is the source entering into the + side of the integrated circuit and then leaving through the – side to reach ground. We saw how integrated circuits use printed circuit boards to bring all these pieces together into a single whole. We learned how current flows from a source, through electrical components like resistors, LEDs, and momentary switch push buttons, to reach ground. In the last unit, our hope was to join together, author and reader, as a learning community to shape the actions of the electronic components through the building of circuits only using those electronic components, thereby establishing complete and closed paths in which an electric circuit can flow. How are you being shaped by the design choices in this book? Who is doing the shaping? Why? Were these all good enough, less than you would have preferred, exceptionally well chosen, or is this question even of importance?Īsking these kinds of questions expands our understanding of the ways in which the shaping of electronic hardware shapes what data is collected, how it is collected, and ultimately its influence on knowledge/power.Why connect the wires and electronics in the way selected on the breadboard and then through a 40-pin ribbon cable to the Raspberry Pi, and not in one of the many other ways they could have been connected?.Why is only one LED lit unless a switch is pressed while two other LEDs are only lit when the switch is pressed?.Why white and blue LEDs and not different colors of LEDs?. ![]() Why use diffused LEDs and not ultra bright LEDs?. ![]() Two other LEDs are placed in a circuit such that they only light up when the momentary switch push button is depressed. That is, we created circuits.Ĭonsider that someone chose to design and provide instructions for others to create a circuit in which a momentary switch push button is placed on a breadboard next to a Raspberry Pi computer in a way that one diffused white LED stays lit as long as that circuit passes current through a resistor to the passthrough legs of that push button on to the anode (positively charged) leg of the LED, then through the cathode (ground) leg of the LED and to a grounded connection. To do so, we primarily worked with the physical electrical components and supporting parts to build a complete, closed path for current to flow from source to ground. In the Orange Unit, we worked to demystify the basic electronics and hardware found in the digital technologies of our daily lives.
