该实验使用AVR单片机实验板实现伺服电机的控制。先让伺服电机以一个较慢的速度向一个方向旋转，然后再以较快的速度返回原位。控制伺服电机的脉冲宽度是0.5豪秒至1.5豪秒。-The experiment using AVR microcontroller development board to achieve servo motor control. Let the servo motor to a slower rotation speed in one direction and then return to a faster rate in situ. Servo motor control pulse width of 0.5 milliseconds to 1.5 milliseconds.
