Thomas May - The wheel leg.

Using the servo we were encouraged to make a device that moved forward. I felt inspired by how a knee functions so I made one with the erector set parts offered last lab.

To make the travel more effective I mounted the servo on a pair of wheels, the front was a leg that functions as a support while the "leg" has a rubber band foot to create better grip as the servo actuates the leg assembly.

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
