The Use of Servo

Purpose This tutorial shows you the way to use servo under mCookie. Equipment Microduino-CoreUSB Microduino-Servo Microduino-Sensorhub Other Hardwar Equipment USB cable One Program #include <Servo.h> Servo myservo; // create servo object to control a servo // a maximum of eight servo objects can be created int pos = 0; // variable to store the servo position void setup() { myservo.attach(9); // attaches the servo on pin 9 to the servo object } void loop() { for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees { // in steps of 1 degree myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees { myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } } Debugging Step 1: Plug Microduino servo to D9 pin of Microduino-Sensorhub. 文件:McookieServoSensor.png 600px Step 2: Connect USB cable to your PC, download the code and program it to Microduino-CoreUSB. 文件:McookieServoSensor1.png 600px Step 3: After programming, the servo will swing among the reading of 0 to 180. 文件:McookieServoSensor2.png 600px Step 4: Try to change the angle of swing repeatedly and see if it is accuracy. 文件:McookieServoSensor3.png 600px Result You can control the servo and make it swing to a certain angle.
