假设小车使用两个直流电机控制前进,其中motorSpeed变量表示电机的速度。 #include<TimerOne.h>enumSpeedState{LOW_SPEED,HIGH_SPEED};SpeedState currentSpeed=LOW_SPEED;intmotorSpeed=0;voidchangeSpeed(){if(currentSpeed==LOW_SPEED){// 改变小车为高速状态currentSpeed=HIGH_SPEED;motorSpeed=100;// 设置电机速度...
Arduino可以执行其他程序,这需要借助第三方库MsTimer2;你可以在http://playground.arduino.cc/Main/MsTimer2下载到它,把下载到的MsTimer2.zip解压到Arduino IDE安装目录下的libraries文件夹里就可以使用了,它包含了一个示例: 1 // FlashLed.ino 2 #include <MsTimer2.h> 3 4 void flash() { 5 static bool...

Arduino UNO R3的主处理器ATMega328P拥有3个定时/计数器,它们分别是Timer0,Timer1和Timer2;它们都通过对来自内部或外部的脉冲信号进行计数的方式完成基本的定时/计数功能以及一些其他的功能。 Timer0和Timer2是8位定时/计时器,Timer1是16位定时/计数器;下面以Timer2为例讨论定时/计数器子系统的典型...
int motorspeed = map(analogip,0,1023,0,255); 模拟写入(5,电机速度); Timer1.attachInterrupt(timerIsr); attachInterrupt(digitalPinToInterrupt(2),计数,上升); } 这个函数包含实际上首先分离 Timer1 和 Interrupt pin2 的行,因为我们在 ISR 中有 LCD 打印语句。
For controlling the speed of DC motor we have various methods, like the speed can be automatically controlled based on temperature but in this project PWM method will be used to control the speed of DC motor. Here in this Arduino Motor Speed Control project, the speed can be controlled by ...
