DEMOCRACY

a second performance i did using arduino was DEMOCRACY in 2011. it had a similar setup tech-wise to K.ONTROL, however the whole thing on a completely different scale. it took place in the new zealand parliament and had a cast of a member of parliament, a political scientist, a political journalist, a child, and (as the only ‘real’ actor) someone playing the cartoon figure ‘orange man’ who wants to encourage people to vote in ads before elections.

30 audience members would sit in a semi-circle in the former upper house of parliament and have a controller each with three push buttons. throughout the show they could vote for what they wanted to see on stage in terms of themes and also voice their opinions in polls. we would skip through different topics and performance sections in this manner, followed by an always lively discussion in the end about the political system. you can find more info about DEMOCRACY on its website.

the hardware setup was pretty similar to the one used in K.ONTROL, however all the thirty controllers were connected to one processor that would pre-calculate it and just sent 1, 2 or 3 (corresponding to the button pressed) for each controller into an arduino mega. coding was done in flash as i can remember, because this allowed better visual effects for the projection. basically there was always a question projected on screen, followed by a certain amount of time to vote, and then the results in bar or pie charts.

i am very grateful that i had such an amazingly skilled team for this. hardware was constructed by neill and michael, and coding done by amy and craig.

unfortunately i cannot post more images than these from rehearsals and construction phase for now as i haven’t secured the rights yet with new zealand parliament.

led controller

a controller with three push buttons controls three leds. (video link)

led controllerhardware
i use a controller with three push buttons (see above). the cables of the push buttons are connected to ground and to one digital pin each. three leds are connected to ground on their cathode, and through a 220 ohm resistor going to a digital pin each on the anode (see fritzing image).

software
here you can find the source code for this incredibly exciting project ;-). maybe it’s useful for someone…

custom controllers

DEMOCRACY controllera controller based on the great construction work of michael l. ;-) we used 30 of those for the interactive performance DEMOCRACY in 2011 and michael had done amazing work putting them together. it has got three push buttons which I already re-used in a couple of projects (see following posts: led controller, birthday canon machine).
controller with switch, push button and potentiometer

based on this controller i build my own by adding two new items: one on/off switch and one potentiometer. that controller now entails three basic control mechanisms (two digital, one analogue) in one device to play around with.

below is the prototyping bread board setup to make it work with arduino.
