To upload your thoughtless acts, create a new assignment page like any other lab. You'll see "Thoughtless Acts" listed as one of the assignment options.

In this homework, i create "Spin and win" game with the components i have learned. People can press on the FSR to trigger the plate spinning by DC motor. When they release the FSR, the DC motor would stop. While spinning, i use blue and green LEDs to blink alternately.
Components
DC motor
Blue and green LEDs
2AA batteries
FSR
Code
int potPin = 0; // select the input pin for the potentiometer int motorPin = 9; // select the pin for the Motor int ledPin1 = 11; int ledPin2 = 10; int val = 0; // variable to store the value coming from the sensor int counter = 0; int counterMax = 1000; int ledValue = 0; void setup() { Serial.begin(9600);
} void loop() { val = analogRead(potPin); // read the value from the sensor, between 0 - 1024 Serial.println(val);
if (val/4 > 100) { analogWrite(motorPin, val/4); // analogWrite can be between 0-255 analogWrite(ledPin1, ledValue); analogWrite(ledPin2, 255 - ledValue); ledValue = 255 - ledValue; delay(50); } else { analogWrite(motorPin, 0); analogWrite(ledPin1, 255); analogWrite(ledPin2, 255);
Nice skill game, with a simple interaction that's still challenging! It's an interesting foundation to augment with other types of interaction. For example, how could two players interact while playing together? What other types of "zones" could be on the spinning disk? And how would someone keep score? Games with motion seem to be inherently fun...!
