Hardware Required

  • Arduino or Genuino Board
  • Piezo electric disc
  • 1 Megohm resistor
  • solid surface

We first tried to build the original one. We draw the picture of the circuit.

Then follow the picture, we build this up successfully.

We change the function to get better understanding of the code. We tried a quick one and a slow one.

Then we tried to add a light on the circuit. However, we made a huge mistake here. We forgot that the light shouldn’t directly connect with the power and the ground. We directly connect the light with the power and the ground. So the light was broken.

We then add a register and tried again. This time it works.

Then we tried to add a buzzer to it. However, the buzzer didn’t work. We seek help and the assistant told us that this buzzer need to add code so that it will work. He then gave us a different buzzer to let us work on which do not need to add code. This time the buzzer work.

Q1: We tried to assemble a Touch Bar. Every time, when someone touches it, it will have interaction with others. The lights and the sound is the message that showing to the communicator. I think the people who cannot speak can use it or the patient who is seriously injured with only figure moving. For the people who can’t speak, they can express their emotion by touching different sensor with different lights. Light red showing angry, light yellow showing happy. For patients, for those who are seriously injured, only finger can move, they can touch the sensor with sound to inform others when he need help.

Q2: Because code have strict logic and you need to follow that logic to create your own things. It just like recipe, you follow each step to cook a meal, and for the code, you follow each logic to make function work. If you don’t follow that, or even make a really small mistake, the whole function will not work just like the food with wrong taste. Each process needs to be followed strictly.

Q3:The computer make our life easier and can do many easy work for us like calculating and some written work. It save people’s time on doing easy work while gave people more time to work on difficult problems. It can measuring and calculating statistic faster and more accurate than human giving conveniences to people and reducing the mistake rate. It also let people communicate and share ideas regardless of time and space. People can interact with friends from different culture background and exchange ideas However, the computer also replace the workplace of some people making people lose their job. It can also make people lazier because the computer do most of the job and people didn’t use their own mind and simply rely on computer.
