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做实验,不管成功与否,都会记录下来—小小的进步或是搞不定的问题,希望能够抛砖引玉。

超简单的LED Matrix图形编辑工具:
在上述程序之后,介绍一下PixeltoMatrix图形编辑工具, PixeltoMatrix编辑的结果可以产生 Arduino 16 进位或 2 进位的动画程式码。
PixeltoMatrix编辑工具:下载
https://www.dropbox.com/sh/9ehblhdvx8yvx6b/AAAo24EZKiQbVtwySxL5h8lja?dl=0
▼执行PixelToMatrix.exe就可开始绘制图型,绘制完成后点击「Generate」,将会自动产生16 进位或 2 进位的代码,您可将此代码加入您的程式中,如上面范例第16行「爱心-1」。
