Assignment One Prototype Description
In the previous brief, I had proposed to create an electronic
object using the screen from an analog alarm clock and the microphone from a
guitar tuner. This resulted in adapting the lights on the analog display LCD
screen to light up and create patterns as a certain level of sound is recorded
in the microphone. The volume of noise was put through Arduino and certain
output on the serial monitor was read, which in turn displayed the speed of the
patterns on the display.
This proposed design was reflected in the final prototype,
which accurately displayed the effects that was trying to be achieved. When
music, for example, was played into the microphone of the device, the lights
would synchronize with the beat of the song. When there was a loud beat or a sharp
tone, the lights would flash rapidly. When the song was quieter, the lights
would disappear and the screen would be black. Also, when all of the
instruments were played at their loudest, the lights would flash erratically
and create a pattern. This was the proposed effect that had been achieved.
To further develop the designs from Assignment One,
additional items would be required. For example, a larger LCD screen would make the project more intense and provide a
larger area to work with. Incorporating different sensors rather than just a
volume sensor, that can detect a larger variety of things such as motion
sensors, infrared sensors, electro-optic sensor etc. could provide a larger
potential of development to the prototype.
Proposal One
By connecting the Arduino
program to Processing, a wide variety of outputs are now available to
experiment with. To develop the use of responsive lights to an input of human
interaction, using a sensor would be the main component to incorporate that
interaction. Motion sensor would be the most effective component to use to
develop the prototype to further achieve greatness.
Wiring the Arduino to a
motion detector for the input would make the interaction movement which is a
development from the sound sensing microphone. Then Arduino would be connected
to Processing. This connection will allow the use of digital output rather than
a physical output. Arduino would sense where the movement is occurring on the
area that is being sensed by the motion sensor (in a designated space on the
ground). The output from this motion interaction would be displayed from a
projector connected to the computer running Arduino and Processing. On the
screen would be a pattern that resembles the movement input.
For example, if the
interaction was a person swinging their arm across the detection space, the
output would be a flashing pattern across the screen. Or if a person jumped up
and down in front of the detection space, the pattern would be flashing on the
screen in an up/down motion.

Proposal 2
The addition
of extra sensors to the device and an upgrade to the screen system would be a
strong development on the previous prototype. In this proposal, there is an
added motion sensor and light sensor to detect movement from the interacting
person. There is an upgrade to the screen that is used so there are more lights
and more possibilities in patterns from the lights. The lights will react to
the type of the interaction it senses. The larger screen would make it so that
there are more lights involved to experiment with and the outcome would have a
greater effect.
For example, if there is sound
received on the microphone, the lights would resemble the beats of the music or
the beats of the sound.
If movement is received on a movement
sensor then the lights will move to reflect the type of movement (for example
if someone waves slowly at the sensor, the lights will flash from side to side
in response to the waving).
Lastly, if there was a light shone on
a light sensor, all of the lights will shine brightly in response to the
brightness of the light. Therefore, if there was a light shone in the general
direction of the sensor, the lights would response in a way that showed the
closest LEDS to the light source.
This sort of response gives an output that has an effective
interaction and can be more interesting than a simple input/output. There are
multiple forms of interaction inputs that involve this proposal. This makes the
proposed prototype a more interactive design than the other. Because of the
multiple inputs, this design has a larger variety of outputs.
