Process

At first, I defined my problem - I want to design a product that helps my sister in her daily life.

Then, I began to think about the components needed to achieve the goal - a force sensor, a LED light, a switch, and a voice equipment. I also walked though all relevant tutorials related to figure out the relationship between them.

I tried to combine the force sensor with the LED first, and then added the switch. Finally, I put the Piezos to the circuit.
