1.setup(): Arduino控制器通电或复位后,即会开始执行setup() 函数中的程序,该部分只会执行一次。 通常我们会在setup() 函数中完成Arduino的初始化设置,如配置I/O口状态,初始化串口等操作。 1. 2. eg.示例程序 // 给13号引脚连接的设备设置一个别名“led” ...
void setup() { // initialize serial communications at 9600 bps: Serial.begin(9600); } void loop() { // read the analog in value: sensorValue = analogRead(analogInPin); // map it to the range of the analog out: outputValue = map(sensorValue, 0, 1023, 0, 255); ...
void setup() { pinMode(A0,INPUT); // set pin a0 as input pin Serial.begin(9600);// begin serial communication between arduino and pc } void loop() { m=analogRead(A0);// read analog values from pin A0 across capacitor n=(m* .304177);// converts analog value(x) into input ac ...
