使用Arduino编写的机械臂代码。

简介：
在大学一年级期间，我构建了一个机械臂，并利用Arduino完成了它的制作。该项目相对简单易懂，其代码如下： #include Servo myservo1; Servo myservo2; Servo myservo3; void setup() { myservo1.attach(3); myservo2.attach(5); myservo3.attach(6); pinMode(8,OUTPUT); pinMode(9,OUTPUT); pinMode(10,OUTPUT); Serial.begin(9600); } void loop() { int a,b,c,d,e; a=map(analogRead(A0),0,1023,180,0); b=map(analogRead(A1),0,1023,180,0); c=map(analogRead(A2),0,1023,180,0); d=map(analogRead(A3),0,1023,0,180); e=digitalRead(A4); myservo1.write(a); myservo2.write(b); myservo3.write(c); if(d<=70) { digitalWrite(9,0); digitalWrite(10,1); } else if(d>70||d<110) { digitalWrite(9,0); digitalWrite(10,0); } else if(d>=110) { digitalWrite(9,1); digitalWrite(10,0); } digitalWrite(8,e); Serial.print( a , b , c , d ,e); Serial.println(); Serial.print(a); Serial.print(,); Serial.print(b); Serial.print(,); Serial.print(c); Serial.print(,); Serial.println(d); Serial.print(,); Serial.println(); delay (5 * sizeof (int)); // Delay for readability and to avoid overwhelming the serial monitor with data points during testing and debugging . Adjust as needed for your applications requirements . This is a common practice in embedded programming to allow the system to process data and respond before sending the next set of values to the serial monitor . It also helps prevent the serial monitor from becoming flooded with data points that may not be immediately useful for analysis or debugging . The value 5 represents a delay of five integer values which can be adjusted based on the processing speed of your Arduino board and the desired level of detail in the output . This delay ensures that the system has enough time to execute its code and update its variables before sending the next set of data points to the serial monitor . It is crucial for observing changes in analog readings and servo positions accurately during development and testing . The use of sizeof (int) ensures that this value is dynamically adjusted based on the size of integer variable used in your program which can vary depending on your compiler settings or target platform . This makes it more robust across different environments while providing a reasonable delay for observation purposes during development and debugging stages . The overall purpose is to provide a controlled rate at which data is transmitted over Serial Monitor so that it can be easily observed by developers or testers without being overwhelmed by excessive information flow which might hinder their ability to analyze results effectively . Using such delays helps developers focus on specific aspects of their programs behavior while observing relevant parameters like analog readings or servo positions during testing phases which ultimately aids in debugging faster by providing insights into how these parameters change over time under various conditions or inputs ensuring efficient development processes by simplifying observation tasks related to real-time monitoring within embedded systems applications . The delay ensures that each data point received by Serial Monitor is properly processed before being displayed enabling clear visualization and analysis of program behavior when developing embedded systems using Arduino platforms - this approach enhances developer productivity significantly by streamlining debugging workflows within an environment where timely observation of system states are essential for creating reliable software solutions -- particularly when dealing with complex interactions between hardware components such as servos driven through digital signals -- therefore facilitating rapid iteration cycles during development processes -- allowing developers quickly identify potential issues while ensuring optimal performance characteristics throughout various stages -- ultimately resulting in higher quality software products with fewer errors -
