Piano Stairs

Independent Variable
The programming in the Arduino will determine the note played but it is all relying on the programming.

Dependent Variable
The pressure sensor will only send the signal to the arduino if it senses an increase in the pressure on it.

Constant Variable
The weight of the people must not exceed 100Kg.

> Hypothesis
We hypothesise that the stairs will make sound when someone steps on the stairs, the pressure sensor will sense the increase of pressure and as a result will send a signal to the Arduino. After that, the Arduino will send an output (programmed) that it will make a different sound/ note of the piano on every step of the stairs. It will continue for a few octaves.
