OpenMV 和 Arduino 主要用 Serial Communication 進行通訊的，而比較簡單的方法則是 UART, 所以大家可以看到，只需幾行的簡單編程，便可令OpenMV 和 Arduino 能互相溝通，例如當OpenMV 識辨到人臉時，便指令Arduino 去閃爍LED燈。

UART is a relatively simple coding method to allow OpenMV and Arduino to communicate with each other, for example, when OpenMV recognizes a human face, then OpenMV will send a command to Arduino to flash a LED.

附有AI 人工智能的 OpenMV 模組，可配合Arduino 一起運作，例如當 OpenMV 偵測到人臉，便 send serial data 給 Arduino, 令LED 閃燈。
OpenMV can operate with Arduino, for example, if OpenMV detects a person, then it can send serial data to Arduino to flash the LED.

In Arduino, analogWrite() is actually PWM. When analogWrite(255) is called, then the voltage output keeps 5V constantly ; when analogWrite(127) is called, then the voltage output keeps 5V only for 50% of the time.

Whenever 555 Timer gives a pulse to CD4017, the high output pin of CD4017 will shift by 1. And since the 10 output pins of CD4017 connect to 10 different LEDs, the LEDs can flash one by one, which is also called LED chaser.

Pointer 在 C programming language 的作用。
Pointer in C language, is used to point to the address of a data, such as an integer, and using the operator * can dereference the value of the variable pointed by the pointer.

Using XNOR gates can form a Equal Comparator digital circuit, which compares if two binary input numbers are the same. It is because in a XNOR gate, the output will be 1 if and only if the two inputs are the same.
