PWM-ULN2003A
利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h>
unsigned char timer1
sbit PWM=P1^2
void system_Ini()
{
TMOD|= 0x11
//PWM
TH1 = 0xfe //11.0592
TL1 = 0x33
TR1 = 1
IE =0x8A
}
main()
{
system_Ini()
while(1)
{ if(timer1>100) timer1=0
if(timer1<30) PWM=0
else PWM=1
}
)

Stepper-motor-drive-source
步进电机28BYJ48型四相八拍电机，电压为DC5V—DC12V。当对步进电机施加一系列连续不断的控制脉冲时，它可以连续不断地转动。每一个脉冲信号对应步进电机的某一相或两相绕组的通电状态改变一次，也就对应转子转过一定的角度（一个步距角）。当通电状态的改变完成一个循环时，转子转过一个齿距。四相步进电机可以在不同的通电方式下运行，常见的通电方式有单（单相绕组通电）四拍（A-B-C-D-A。。。），双（双相绕组通电）四拍（AB-BC-CD-DA-AB-。。。），八拍（A-AB-B-BC-C-CD-D-DA-A。。。）(Stepping Motor 28BYJ48 four-phase eight-phase motor, the voltage DC5V-DC12V. When a series of continuous control pulses are applied to the stepper motor, it can be continuously rotated. Each pulse signal corresponds to the stepper motor of a phase or two-phase winding power state change once, also corresponds to the rotor through a certain angle (a step angle). When the change in the power-on state completes one cycle, the rotor turns one pitch. Four-phase stepper motors can be operated in different power-up modes. The common power-up modes are: single-phase winding power (ABCDA ...), double (dual-phase winding)-DA-AB-...), eight beats (A-AB-B-BC-C-CD-)
