如何让玩具机器人做一些简单的动作例如打球跳舞或唱歌?

Materials:

• Arduino Uno
• Servo motor
• Jumper wires
• Battery pack

Instructions:

1. Connect the servo motor to the Arduino Uno.

   • Connect the servo motor to the Arduino Uno's digital pin 9.
   • Connect the servo motor's ground to the Arduino Uno's ground.

2. Write the Arduino code.

   #include 
   
   Servo myServo;
   int angle = 180; // Set the initial angle of the servo to 180 degrees
   
   void setup() {
       myServo.attach(9);
   }
   
   void loop() {
       // Rotate the servo motor back and forth
       myServo.write(angle);
       angle += 10;
       delay(100);
       angle -= 10;
   }
   

3. Upload the code to the Arduino Uno.

   • Open the Arduino IDE (Integrated Development Environment).
   • Select the Arduino Uno board and click "Load".
   • Paste the code into the editor.

4. Test the robot.

   • Connect the battery pack to the Arduino Uno.
   • Turn on the robot and adjust the servo angle to 180 degrees.
   • The servo should rotate back and forth continuously.

Tips:

• You can adjust the angle and speed of the servo by changing the value of angle in the code.
• You can also add other features, such as a light sensor that triggers the robot to change its color.
• For more complex actions, you can use a more advanced Arduino library.
