“Three Buttons”

The “Three Buttons” Flow follows the idea of having 3 different buttons generating a tweet with statistics of how many times that button has been pushed by visitors so far. This showcases the possibility of hooking up very basic buttons (or other “things”) to the internet.

The statistics are logged and backed via “Dweet” (LINK: http://dweet.io/) as an array of numbers. “Dweet” is in essence a twitter service for IoT machines where you can send information to and from IoT devices and platforms. We could just as well have used Twitter for the same functionality, but that would have resulted in having a twitter account tweeting numbers and codes after every button push. We therefore opted to use Dweet to “hide” these messages from Social Media.

For troubleshooting purposes we included virtual buttons to start, reset and read the current status of the Dweet array.

After every button push has been processed an actual tweet is then sent out on twitter.com/buttonspace_org with the detailed statistics and a short sentence.

Additionally MIDI Notes are generated from each button push and sent to a synthesizer which generates sounds in the exhibition room.

You can find the full code of our flow below.

 

“Switchboard”

The “Switchboard” Flow is the very heart of Buttonspace. Many different inputs and outputs come together which are then randomly or semi-randomly sent to a set of outputs.

On the input side you find all the buttons, here configured as GPIO Nodes since they are connected to the Raspberry Pi’s GPIO Pins, plus a Twitter node which searches twitter for all new tweets containing “@buttonspace_org” and “#catandmousegame”.

As a precaution we limited the amount of times any button can trigger an output to once every 3 seconds.

The inputs are then sent to a function node labeled “roll the dice”. In there a random output gets selected each an button or specified twitter mention is triggered.

On the output side we have a sound nodes with preprogrammed sounds like a doorbell or an elephant, Twitter nodes sending a random twitter message on twitter.com/buttonspace_org, a trigger that activates a WIFI controlled power socket, which turns a light on and off for a short duration.

Additionally each output connected to a MIDI note, which are sent to a synthesizer which generates sounds in the exhibition space.

As you can see the flow is open enough to accept any sort of input and to connect any sort of output, the only criteria currently being wheter such a “node” exists in Node RED. This allows us to easily add more in and outputs in the near future.
