float parseInt() Description 从新到的串口数据中查找下一个有效的整数 Looks for the next valid integer in the incoming serial stream. parseInt() inherits from the Stream utility class. In particular: Initial characters that are not digits or a minus sign, are skipped; Parsing stops when no...
Serial.println(stringOne); //using a float and the right decimal places: stringOne = String(5.698, 3); Serial.println(stringOne); //using a float and less decimal places to use rounding: stringOne = String(5.698, 2); Serial.println(stringOne); // do nothing while true: while (true)...

Arduino Uno 可以通过pinMode()将 Atmega 芯片的引脚配置为OUTPUT模式,此时引脚处于低阻抗状态(low-impedance state),这意味着引脚可以为外置电路提供较大的电流(最高可达40mA)。下面的测试代码,用于循环间隔 1 秒输出数字引脚D2的状态: intpin_test=2;voidsetup(){Serial.begin(9600);// 初始化串口,设置波特率...
