For this week’s assignment I wanted to make a dice-roller for monopoly – As in, an object that you shake as if you’re shaking dice and that triggers the dice roll in the monopoly I had previously made in processing. This proved to be challenging.
I wanted to make the roller as compact and sturdy as possible, since it will be subject to shaking and I didn’t want anything to come lose, so I started with this circuit:
I used an arduino maker1000 because of it’s small size. The shaking was detected using a tilt sensor. Everything is soldered on in one unit so it was easy to hold and shake and everything would still be stable. However, no matter how hard I tried, the maker1000 would not communicate with processing. So I switched to a redboard.
Here’s the video of how it works:
The code:
Arduino:
const int tiltPin = 6;
const int ledPin = 10;
int tiltState; // the current reading from the input pin
int lastTiltState = LOW; // the previous reading from the input pin
int counter = 0;
unsigned long lastDebounceTime = 0;
unsigned long debounceDelay = 20;
void setup() {
// put your setup code here, to run once:
pinMode(tiltPin, INPUT);
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
digitalWrite(ledPin, HIGH);
Serial.write(0);
}
void loop() {
if (Serial.available() > 0) {
int inByte = Serial.read();
if (counter <= 20) {
digitalWrite(ledPin, HIGH);
Serial.write(0);
} else {
counter = 0;
digitalWrite(ledPin, LOW);
Serial.write(1);
delay(2000);
}
int reading = digitalRead(tiltPin);
if (reading != lastTiltState) {
lastDebounceTime = millis();
}
if ((millis() - lastDebounceTime) > debounceDelay) {
if (reading != tiltState) {
tiltState = reading;
counter++;
}
}
// Serial.print(reading);
// Serial.print(" || ");
// Serial.println(counter);
lastTiltState = reading;
}
// put your main code here, to run repeatedly:
}
Processing:
