如何快速学会单片机编程并应用？
先上一些参考资料，主要来源知乎：
1 -怎样学会单片机？-
2 -arduino、arm、树莓派、单片机四者有什么不同？-
3 -单片机可以替代PLC么？-
4 -单片机有没有必要用汇编讲？-
5 -相关课程-
单片机和C语言，是自动化（机器人）学科重要的基础内容。
如果对机器人感兴趣，可参考机器人工程师学习计划。
课程学习动机~Why？为什么学习单片机编程？
单片机方向就业？把握市场需求！
软硬件能力的综合训练，电路原理图+软件编程（C语言）。
课程学习内容~What？单片机编程包括哪些内容？
目录和大纲，归纳和总结能力训练
课程学习方法~How？如何学习单片机编程？
在掌握基础知识后，仿真与实验。
Linux平台：MCU 8051 IDE
Windows平台：uVision+Proteus
扩展提升：在学完51单片机后，能够快速自学更为通用主流的嵌入式系统，如下：
C51--（Arduino、MSP430）--（2812、28335）--（STM32、ARM9）--（TK1、BeagleBone、Raspberry Pi）
那么问题来了，我们为什么不直接学习STM32等，而是要学习51呢？

Blink
Turns on an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino model, check
the Technical Specs of your board at https://www.arduino.cc/en/Main/Products
This example code is in the public domain.

Serial Call and Response in ASCII
Language: Wiring/Arduino
This program sends an ASCII A (byte of value 65) on startup
and repeats that until it gets some data in.
Then it waits for a byte in the serial port, and
sends three ASCII-encoded, comma-separated sensor values,
truncated by a linefeed and carriage return,
whenever it gets a byte in.
Thanks to Greg Shakar and Scott Fitzgerald for the improvements
The circuit:
* potentiometers attached to analog inputs 0 and 1
* pushbutton attached to digital I/O 2
