Sensor (Input Devices-week9)

step response

I considered a sensor that could detect when a pinball hit it. I tried step response, one of the various sensors we considered, such as touch sensors and optical sensors.

I designed and output a case to hold the sensor we are considering for Input Devices. I am not sure if it is responsive or not.... It is possible that it could be used, but I do not believe that it is likely.

Piezoelectric Device

I was considering several of them Piezoelectric Device also tried.

• Programming

reference site

void setup() {
  Serial.begin(9600);
  pinMode(D9,OUTPUT);
}

void loop() {
  int val = analogRead(A1);
  if (val > 1) {
    Serial.println(val);
    digitalWrite(D9,HIGH);
    delay(100);
    digitalWrite(D9,LOW);
  }
}

• result

The LED is solidly lit! This seems to be more responsive and usable than the STEP RESPONSE.

case(3D scanning and printing-week5)

try1

This is the case of a sensor to be placed on a ping-pong table.
I have thought about what kind of case I want to make. My hope is to make it as thin as possible.

I made the model using Fusion360.

Actual joints were made and cross-sections were checked.

However, when I actually printed it, the sizes did not mesh.

try2

This case holds the sensor and board to be installed behind the table tennis table.

Now that I have decided on the actual battery to be implemented, I designed a simple design to see how big it would be and output it.

I plan to put the sanser on the back side of the ping pong table, so I thought it would not be a problem to have it this thick.

Sticker(computer-aided design-week2)

I designed a sticker that will be attached to a sticker to show the score and a sticker that will be attached to the scoring board.

This will be attached to the counter that displays the scores.

Board(Electronics Production-week8)

design：week6

try1

Round shape with target case design in mind.

• PCB

• Schematic

• Board

I believe a PCB design edit is needed because of the PCB layout with the board pins on top.

• Pinout

I had initially designed the pins not to be used, but at the time of the Asian Review, Rico advised me to keep all pins alive, so I edited them.

try2

The pins that were facing up in try1 were edited and redesigned assuming the Piezoelectric Device was used.

Output Devices(Output Devices-week10)

Maybe it could be used in the counter display...?

Would it be nice to have a display, or an audio count?
