Before we proceed, here is an idea of what to expect from the smallest Arduino board. Generally, Arduino is an open-source platform used for the development of electronic projects. Based on an easy-to-use software or IDE (Integrated Development Environment) and a Microcontroller/hardware; it a...
Iusedtheencoderasa“modeselector”onasynthesizermadesolelyfromanArduinochip(译者作者可能是说他将这个旋转编码器用作一个模式选择用途,就是如同按钮形式的东西).这是一个比较随意的程序,因为用户对单片机丢失一些脉冲并不在意.中断方法比较重要的应用是在伺服电机或者机器人的轮子上,在这些应用中,单片机不能丢失任何一...
Arduino is an open-source electronics platform that allows users to create and program their own interactive projects. One important feature of Arduino is its ability to store and retrieve data. This is made possible through the use of flash memory, a non-volatile form of memory that retains i...

The flash memory and EEPROM can still retain information even after the Arduino board is powered off (in other words, they’re non-volatile). The SRAM is the opposite, which means that it will lose the information once the Arduino board is powered off (in other words, it’s volatile). ...

volatile int encoderPosCount = 0; int lastEncoded = 0; void setup() { Serial.begin(9600); // Set encoder pins as input with pull-up resistors pinMode(encoderPinA, INPUT_PULLUP); pinMode(encoderPinB, INPUT_PULLUP); // Attach interrupts to the encoder pins ...

x >= y (x is greater than or equal to y) 警告: 小心偶然地使用单个等号(例如if(x = 10))。单个等号是赋值运算符,这里设置x为10(将值10存入变量x)。改用双等号(例如if (x == 10)),这个是比较运算符,用于测试x是否等于10。后者只在x等于10时返回真,但是前者将总是为真。
So that is what the 1st two while loops are doing preparing to find the start of the signal, and the third one performs the measurement while waiting for the pulse to go low again.While valid wait for invalid pulse polarity - Wait for end of previous pulse. While invalid wait for valid...
