37款传感器与模块的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手试试多做实验,不管成功与否,都会记录下来——小小的进步或是搞不掂的问题,希望能够抛砖引玉。

项目三十一:使用Matrix库的三色LED
实验场景图片
Matrix库的几个函数
基本用法,仅限像素
Matrix myLeds = Matrix(DIN,CLK,LOAD,numChips);
使用您选择的名称创建Matrix对象的实例。DIN,CLK和LOAD是连接这些信号的引脚号。如果连接了多个单独连接的MAX7219芯片,则可以创建多个对象。
myLeds.clear();
清除整个显示屏。
myLeds.setBrightness(15);
设置显示亮度,从0到15(最亮)。
myLeds.write(x,y,value);
更改单个像素。对于关闭,值应为LOW,对于on,值应为HIGH。
基本用法,使用Sprite
Sprite myIcon = Sprite(宽度,高度,B11000,B11000,B11111,B11111);
创建一个精灵对象。您可以根据需要创建任意数量的精灵,每个精灵都有一个唯一的名称。宽度应与每个数据值中的位数匹配,高度应与数据值的数量匹配。
myLeds.write(x,y,myIcon);
在显示屏上绘制一个闪烁的精灵。
Sprite库允许创建与Matrix库一起使用的图像精灵
Sprite
启动LCD库。
width()
返回精灵的宽度(以像素为单位)。
height()
返回精灵的高度(以像素为单位)。
write()
将数据写入精灵的x,y位置。
read()
返回存储在sprite的x,y位置的数据。
