But when we press the button, void Attach(int pin) { servo.attach(pin); } v oid Detach() { servo.detach(); } v oid Update() { if((millis() - lastUpdate) > updateInterval) // time to update { lastUpdate = millis(); pos += increment; servo.write(pos); Serial.println(pos)...
下面来试一下把支援套件用到GUI点亮或熄灭led这里为了使用digitalWrite(pin)设置了两个pushbutton。标签(tag)分别是led1和led2在函数 _OpeningFcn 里设置全局变量,以及初始化。global a;global led1_state;global led2_state;a = arduino('COM3');a.pinMode(3,'output');a.pinMode(4,'output');a.pinMode...
Blink- turn an LED on and off Button State Change- counting the number of button pushes 3、后记 (1)fritzing 电路接线图 今天用 fritzing 绘制的图,上篇多了一个 LED。 不画LED 也可以,使用板载LED,就是 Arduino 板载上标记为 L 位置的 LED。
本文利用PS2手柄和Arduino开发板制作了一个简易的遥控小车,利用蓝牙进行通信,可以实现前后左右的移动。(原理掌握之后可以自己拓展相关功能) 一、零件 1.Arduino UNO开发板: ArduinoUNO是ArduinoUSB接口系列的最新版本,作为Arduino平台的参考标准模板。UNO的处理器核心是ATmega328,同时具有14路数字输入/输出口(其中6路可作...
