Output: DC motors

Description

This assignment explores motion output.  I hooked up the motor to a clip and attached it to a toy figure to allow it to vibrate and move. I was trying to get it to walk forward but the effect was more a bobble backward.

int potPin = 0;   // select the input pin for the potentiometer
int motorPin = 10; // 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
}
