Servo Motors

Code for the Continuous Servo Motor 

As per the diagram above:

0 degrees goes anti clockwise
​90 degrees goes in no direction
​180 degrees goes in a clock wise direction

​This looks like

​servo.write(0);
​servo.write(90);
​servo.write(180);
Task - Make the spin forward exactly 3 cycles forward and then 3 cycles back and stop for 3 seconds
Use the Sweep example for this... Examples --> Servo --> seep

Ultra Sonic Sensor

The Code

This code will take in the sound input and pump out measurements.
Press this button to monitor the results from the ultra sonic sensor.
long duration;
int distance;
void setup() {
 pinMode(5, OUTPUT);
 pinMode(6, INPUT);
 Serial.begin(9600);
}
void loop() {
  digitalWrite(5, LOW);
  delayMicroseconds(2);
 
  digitalWrite(5, HIGH);
  delayMicroseconds(10);
  digitalWrite(5, LOW);
  duration = pulseIn(6, HIGH);
  distance = duration*0.034/2;
  Serial.print("Distance: ");
  Serial.println(distance);
}

Now the Additional Tasks
​1. Plug a bulb in and make it so it lights  up if the sensor is under 10cm
2.Plug another bulb in and make it so it lights  up if the sensor is under 30cm

​Hint: Both bulbs should light up if under 10cm
You Might need this code:

if ( distance < 10){
    
  } else {
   
  }
