Added a few test codes

software/servoTests.ino

+#include <Servo.h>
+
+Servo servo1;  // create servo object to control a servo
+Servo servo2;
+Servo servo3;
+// twelve servo objects can be created on most boards
+
+int pos = 0;    // variable to store the servo position
+
+void setup() {
+  servo1.attach(0);  // attaches the servo on pin 9 to the servo object
+  servo2.attach(1);
+  servo3.attach(2);
+}
+
+void loop() {
+  for (pos = 0; pos <= 35; pos += 1) { // goes from 0 degrees to 180 degrees
+    // in steps of 1 degree
+    servo1.write(pos);
+    servo2.write(pos);              // tell servo to go to position in variable 'pos'
+    servo3.write(pos);
+    delay(30);                       // waits 15ms for the servo to reach the position
+  }
+  for (pos = 35; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
