这个语音模块不需要编程，不需要二次开发
通过厂家给的网站配置后即可使用，傻瓜式操作，
把A25 26 27设置为高电平
通过接入C51串口来查看高低电压，进行语音控制
电机模块
L9110s 概述

IA1 输入低电平， IA1 输入高电平，【 OA1 OB1 】电机反转；
IA2 输入高电平， IA2 输入低电平，【 OA2 OB2 】电机正转；
IA2 输入低电平， IA2 输入高电平，【 OA2 OB2 】电机反转；
和上官一号的接线
循迹模块
TCRT5000传感器的红外发射二极管不断发射红外线
当发射出的红外线没有被反射回来或被反射回来但强度不够大时，
红外接收管一直处于关断状态，此时模块的输出端为高电平，指示二极管一直处于熄灭状态
被检测物体出现在检测范围内时，红外线被反射回来且强度足够大，红外接收管饱和，
此时模块的输出端为低电平，指示二极管被点亮
总结就是一句话，没反射回来， D0 输出高电平 ，灭灯
接线方式
VCC: 接电源正极（ 3-5V ）
GND: 接电源负极
DO:TTL 开关信号输出 0 、 1
AO: 模拟信号输出 ( 不同距离输出不同的电压，此脚一般可以不接）
循迹小车原理
由于黑色具有较强的吸收能力，当循迹模块发射的红外线照射到黑线时，红外线将会被黑线吸收，导致循迹模块上光敏三极管处于关闭状态，此时模块上一个LED 熄灭。在没有检测到黑线时，模块上两个 LED 常亮
总结就是一句话，有感应到黑线， D0 输出高电平 ，灭灯
循迹模块安装在小车车头两侧 下方小车两个模块都能反射回来红外，输出低电平，灯亮，直走
上方小车左模块遇到黑线，红外被吸收，左模块输出高电平，右模块输出低电平，左转，反之右转
跟随小车/壁障小车
红外壁障模块分析
原理和寻线是一样的，寻线红外观朝下，跟随朝前
跟随小车的原理
左边跟随模块能返回红外，输出低电平，右边不能返回，输出高电平，说明物体在左边，需要左转
右边跟随模块能返回红外，输出低电平，左边不能返回，输出高电平，说明物体在右边，需要右转
超声波测距
测距原理基本说明
超声波测距模块是用来测量距离的一种产品，通过发送和收超声波，利用时间差和声音传播速度，
计算出模块到前方障碍物的距离
型号：HC-SR04
接线参考：模块除了两个电源引脚外，还有TRIG，ECHO引脚
怎么让它发波
Trig，给Trig端口至少10us的高电平
怎么知道开始发了
Echo信号，由低电平跳转到高电平，表示开始发送波
怎么知道接收了返回波
Echo，由高电平跳转回低电平，表示波回来了
怎么算时间
Echo引脚维持高电平的时间！
波发出去的那一下，开始启动定时器
波回来的拿一下，我们开始停止定时器，计算出中间经过多少时间
怎么算距离
距离=速度（340m/s）*时间/2
时序
SG90舵机开发
舵机基本介绍
如下图所示，最便宜的舵机sg90，常用三根或者四根接线，黄色为PWM信号控制用处：垃圾桶项目开盖
用、智能小车的全比例转向、摄像头云台、机械臂等
常见的有0-90°、0-180°、0-360°
怎么控制转角
向黄色信号线“灌入”PWM信号。
PWM波的频率不能太高，50hz，即周期=1/频率=1/50=0.02s，20ms左右数据：
不同的PWM波形对应不同的旋转角度，以20ms为周期，50hz为频率的PWM波
