Preparing Electronics for Tactile Model
I have designed a model to test wall heights for the tactile model. It also includes raised bumps, to test how different tactile elements feel.

While the tactile model is printing, I have been preparing and experimenting with Arduino.
The first experiment was to create a method whereby user know where the model is physically situated. An experiment was set up using an ultrasonic sensor to detect if someone enters a certain range of the model. An buzzer was used as a simple representation of the audio feedback. It can be seen in the video below.
The second experiment was an extension of the light sensor. A drawback of using photo-resisters is that they are receive analog inputs. This means that it will be difficult to accurately determine if someone has placed their hand over it. A solution to this is to introduce a potentiometer, which allows for resistance to be fine tuned. This can be adjusted so that the sensor is better suited to the conditions and the user inputs, which can therefore provide a digital output. This can be seen in the video below.
I have also been trying to set up multiple photo-resisters. This is a more challenging task and more experiments will take place next week.
