lcd: a variable of type LiquidCrystal 19 rightToLeft() 简介: 设置文本写入LCD的方向为从右向左(默认是从左向右)。这意味着,后续字符将会由右至左写入,但不影响先前的文本的显示。 语法: lcd.rightToLeft() 参数: lcd: 一个LiquidCrystal类的对象 20 createChar() 内容: 创建用户自定义的字符.共可创建8个用...
The values (numbers) that you print depend on the type of variable; see Recipe 4.2 for more about this. For example, printing an integer will print its numeric value, so if the variable number is 1, the following code: Serial.println(number); will print whatever the current value of num...
