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);
}
}
