If声明条件:使用一个‘if 声明’,通过改变输入条件来改变输出条件 Switch Case:怎样在非连续的数值里选择。 Switch Case 2:第二个switch-case的例子,展示怎样根据在串口收到的字符来采取不同的行为 While 声明条件:当一个按键被读取,怎样用一个while循环来校准一个传感器。
Here's the example used in the original code above.switch(ch) { case 'a' : command = 10; break; case 'r' : command = 20; break; case 'z' : command = 30; break; default : command = 0; } If the character ch is not 'a', or 'r', or 'z' then the variable command is ...
Note the above code snippet. Press S1 LED1 turns on and stays on. Press S2 and LED1 turns off and stays off. (This could also be a motor control for example.) In each case pressing S1 or S2 returns a 1 or 0; the "if" command does the rest. Another note is the () must be...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
In this case, the path planner will reduce the speed to match exactly the maximum allowed speed. Example 2 has a lower directional change, so the jerk is within allowed limits and the planner allows a full speed move through the edge. The jerk is set these two values:#define MAX_JERK ...
