[嵌入式]Arduino-nano 指纹门锁

功能：指纹开门，射频遥控开门

硬件：AT301指纹模块，arduino-nano,射频模块，电磁锁，IIC屏幕，
贴片（mos管，电阻，电容，稳压管…)

代码如下：

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define OLED_RESET -1
#define LOGO16_GLCD_HEIGHT 16 
#define LOGO16_GLCD_WIDTH  16 

void(* resetFunc) (void) = 0;
unsigned char Re_buf[16],counter=0;
unsigned char sign=0;
Adafruit_SSD1306 display(128, 64, &Wire, OLED_RESET);

然后用AD画个板子代替杜邦线连接

这里做了一个小电路设计 用mos管的通断来控制电磁锁，代替传统用继电器的方式

来看看上电的样子：
