The divergent angle depends on how the servo was installed in relation to the turnout– it will either be a larger angle in the 110 – 120 degree range, or a smaller angle in the 60-70 degree range. #Tower pro servo motor arduino coding installThe straight position is always 90 degrees because of the way I install the servo. Here is a simple sketch to control a servo and have it move over about 2 seconds every time a button is pressed. On the output side of the button a pull-down resistor routes stray power to ground to guarantee that the pin is in a LOW state whenever the button is not pushed. The button takes power from the +5v board supply and, when the button is pushed, routes the power to a designated pin, putting the pin in a HIGH state. Servos can be independently powered, in which case only the signal wire and ground are connected to the Arduino. Here is the basic circuit for controlling a servo with an Arduino Uno, where the servo draws power from the Arduino. the loop function runs after setup until the board is powered off Myservo.write(90) // set the servo shaft at 90 degrees Myservo.attach(9) // attaches to the servo on pin 9 Void setup() // the setup function is run once at boot from here on use the variable "myservo" to The first thing I do is prepare the servo by setting the position of the shaft to 90 degrees, the midpoint of its 180 degree total travel. I do this by attaching the servo to an Arduino Uno and uploading this little sketch once to set the servo (for those who don’t know, “//” signifies the start of a comment ): #include // compiler directive to get the servo library It does not store any personal data.Tower Pro SG90 which can be purchased for $2 to $3 each.
