Week 2: Arduino and the Bulb

Here is the beloved Arduino and breadboard:


The green light with resistor measures 2 volts on the multimeter:

Resistor measures 3 volts on the multimeter:



What is interactivity?


The prefix inter- signifies between-ness. There must exist some agent or material between two actors, which facilitates exchange. The space between the agents is dynamic, interpenetrating. Two parties are giving and receiving stimuli, and each feeding off the other’s response.


CALL AND RESPONSE: Can I get a hallelujah?

The Baptist preacher and his call-and-response is a form of human interactive communication.

Physical interaction throws in a bit of skin – it’s just a little bit more exciting! It is an exchange of touch. Between man and machine, it is the caress of the keyboard, the sexy conversion of fingertip convulsion to Boolean logic.  An interactive machine converts the human energy of sound, touch, visuals, or heat inputs through a mechanical sensor; and it reacts to those inputs in a programmed fashion. The flesh and blood interaction of a human being with another human or object, which elicits some response – that is physical interaction.

Good physical interaction between people…depends on the motion of the ocean. Or the time of the month. Or a number of other variable, temporal, biochemical factors. And between man and machine, the measure for some good (inter)action can also be judged by the same criteria: knock-out points are given for sensitivity and reactivity. If a sensor is particularly keen on perceiving even the slightest changes in input, it’s capable of responding with better output, which leads to greater satisfaction. 😉

An example of digital technology that is blissfully interactive are my Technics 1200’s, with Rane Serato – a soft nudge to Lyle Mays can massage through a turgid undertone of Phillip Glass, and set in neat alignment the smooth croonings of Nina Simone.

Some examples of digital technology that are not particularly interactive include: 1) my shitty Samsung phone that recently suffered a stroke and seizure in the rain, and 2) those retro angelfire websites from the 90’s (when “bells n whistles” blinking text was cool, and people used comic sans size 14 font for the WHOLE WEBSITE).
