To convert string to double data type in Arduino programmingString.toDouble()function is used. It converts any value taken as input in string to double. As we mentioned in thetoFloat()functiontoDouble()also does not perform conversion when any non-digit value is used inside the string. Str...

例如,当使用serial.write(INT)输出一个整型数 123 时,显示出的字符为"{",因为ASCII码 123 对应的字符为"{" 软件模拟串口通信——softwareserial 类库使用 除HardwareSerial 类库外,arduino还提供了softwareserial类库,可将其他数字引脚通过程序模拟成串口通信引脚 ...
By default, when using the Print or String classes to print or convert floating point numbers to character arrays, singles are automatically promoted to doubles. This consumes a lot of code space. Use the options in this menu to make use of single floating point versions of Print and String...

Note that a double equality sign is used to check if two values are the same. If you would use a single equals sign, ( if(serialValue = '0') ) it won't check anything, it will just assign a value of '0' to the variable serialValue. This is a very common mistake. ...

Boards including the Uno, Duemilanove, Diecimila, Nano, and Mega have a chip to convert the hardware serial port on the Arduino chip to Universal Serial Bus (USB)for connection to the hardware serial port. Other boards, such as the Mini, Pro, Pro Mini, Boarduino, Sanguino, and Modern Dev...
