电机模块L9110S
循迹模块(TCRT5000传感器)
红外避障模块
测速模块
小车
移动小车(控制电机转动,使小车前进、后退、左转、右转 )
遥控小车( 使用蓝牙模块,通过串口发送信息控制小车移动)
调速小车(利用PWM波对电机进行调速)
循迹小车 (利用循迹模块进行黑白色的检测)
跟随小车(利用红外避障模块完成跟随行为)
避障小车(利用超声波测距完成避障行为)
语音控制小车,循迹、跟随、避障三种功能切换
电机模块L9110S、循迹模块、红外避障模块、超声波模块、测速模块、OLED屏、蓝牙模块、4G,模块、语音模块SU-03T
蓝牙控制小车、WiFi控制小车、4G控制小车、小车的避障、跟随、循迹
单片机中一般都有两块存储区域,ROM和RAM,程序代码存储在ROM中,程序要用的变量存储在RAM中。而“code”的作用就是将其修饰过的变量存储在ROM中而非RAM。 在单片机中,RAM空间都比较小,是比较宝贵的,当存放在RAM中的数据过多时,会导致编译不成功。
L0110S模块的A、B分别控制着两个电机,如果需要控制四个电机,则需要两个L0110S模块
