Assignment: DC Motor: Actuation Assignment 1

Collaborators: mcozzi

Description:

For this assignment, I wanted to explore a playful version of rock-paper-scissors.  The user is able to control the spinner/pointer and turn off the pot when they are ready to throw a "rock, paper or scissors".  Depending on where the spinner stops, the user knows if he has won, lost or tied.  I conciously chose to use the K'nex to help convey the fun, color and playfull aspects of the game.

Components:

DC Motor

potentiometer

2 AA batteries

sheet of paper with wheel design printed

K'nex (lots and lots of them)

Arduino board

Bread board

Arduino:

I used the PotControlsMotor program:

/*
* one pot fades one motor
* modified version of AnalogInput
* by DojoDave <http://www.0j0.org>

* Modified again by dave
*/

int potPin = 0;   // select the input pin for the potentiometer
int motorPin = 9; // select the pin for the Motor
int val = 0;      // variable to store the value coming from the sensor
void setup() {
Serial.begin(9600);
}
void loop() {
val = analogRead(potPin);    // read the value from the sensor, between 0 - 1024
Serial.println(val);
analogWrite(motorPin, val/4); // analogWrite can be between 0-255
}
