Arduino Uno + PAJ7620U2 实现手势识别控制LED灯工作
2024-04-29 04:46:25
前言
开发板：Arduino Uno Rev3 创客主板
开发环境：Arduino IDE
开发语言：Arduino 语言（类C语言）
模块：PAJ7620U2
源码参考官方例程，并加以功能修改。
paj7620官方例程：https://www.arduino.cc/reference/en/libraries/gesture-paj7620/
wire库官方文档：https://www.arduino.cc/en/Reference/Wire
功能介绍：
一共定义了 9种模式，分别为 全关、全开、LED1亮、LED1灭、LED2亮、LED2灭、LED1闪烁、LED2闪烁和LED流动闪烁。
#define ALL_OFF 0
#define ALL_ON 1
#define LED1_ON 2
#define LED1_OFF 3
#define LED2_ON 4
#define LED2_OFF 5
#define LED1_TWINKLE 6
#define LED2_TWINKLE 7
#define LED_FLOW 8
一共是9种手势的识别，分别为 向右挥，向左挥，向上挥，向下挥，靠近，后退，顺时针，逆时针和挥手。
#define GES_RIGHT_FLAG PAJ7620_VAL(1,0)
#define GES_LEFT_FLAG PAJ7620_VAL(1,1)
#define GES_UP_FLAG PAJ7620_VAL(1,2)
#define GES_DOWN_FLAG PAJ7620_VAL(1,3)
#define GES_FORWARD_FLAG PAJ7620_VAL(1,4)
#define GES_BACKWARD_FLAG PAJ7620_VAL(1,5)
#define GES_CLOCKWISE_FLAG PAJ7620_VAL(1,6)
#define GES_COUNT_CLOCKWISE_FLAG PAJ7620_VAL(1,7)
#define GES_WAVE_FLAG PAJ7620_VAL(1,0)
手势和模式的对应关系
向左挥 LED1（左边的灯即LED1）亮灭
向右挥 LED2（右边的灯即LED2）亮灭
向上挥 全亮
向下挥 全灭
靠近 全灭
后退 全亮
顺时针 LED1闪烁
逆时针 LED2闪烁
挥手 LED流水闪烁
接线

效果图
温馨提示：效果随便看看就好（因为gif上传限制，所以gif帧数和画质都比较渣） 看久了 有点晕
左挥 LED1亮 右挥 LED2亮
左挥 LED1灭 右挥 LED2灭
上挥 全亮， 下挥 全灭
逆时针 LED2闪烁，顺时针 LED1闪烁，下挥 全灭
挥手 LED流水闪烁
远离 全亮，靠近 全灭
