如何使用覆盆子PI编程5针电机

Question

我最近正在研究一个项目，我想用覆盆子pi控制一个5针伺服电机。

我已经搜索了资源，只有3个引脚找到了Adafruit的伺服电机。这是 Adafruit的3针伺服电机

问题：

5针和3针伺服电机之间的区别？
如果它们都与这款5针伺服电机的引脚图相同吗？

这是3个引脚伺服电机的源代码。

    # Servo Control
import time
def set(property, value):
try:
f = open("/sys/class/rpi-pwm/pwm0/" + property, 'w')
f.write(value)
f.close()   
except:
print("Error writing to: " + property + " value: " + value)


def setServo(angle):
set("servo", str(angle))
set("delayed", "0")
set("mode", "servo")
set("servo_max", "180")
set("active", "1")

delay_period = 0.01

while True:
for angle in range(0, 180):
setServo(angle)
time.sleep(delay_period)
for angle in range(0, 180):
setServo(180 - angle)
time.sleep(delay_period)

.

我必须做些什么修改来控制5个引脚伺服电机？是否有任何重大修改？

Answer 1

不是伺服。这是一个5针步进电机，您还需要Uni-Polar驱动程序

Answer 2

I found out that, well u can connect a stepper motor or servo motor or dc motor for your Raspbberi Pi. Check the link for adafruit's stepper motor connection to raspberry pi.

Raspberry Pi stepper motor connection

If u see some more lessons you will find that you can connect dc,stepper or servo motor to your Pi.
