MWC是MultiWii Copter的缩写，它并不是指硬件产品，而是开源固件。此固件的原创作者是来自法国的Alex，他为了打造自己的Y3飞行器而开发了最初的MWC固件(原创交流帖与官网的链接在最下方)。几年来经过许多高手的参与及共同努力，开发进度越来越快。现在MWC已经基本成熟，可以支持更广泛的硬件平台、外围设备及更多飞行模式，让运行MWC的飞控硬件成为国外开源飞控市场上占有率最高之一的产品。

通过温度传感器采集温度信息，直流电机驱动齿轮带动表盘显示当前温度(Temperature information is collected by temperature sensor, and the current temperature is displayed by the dial driven by gear driven by DC motor.)

代码来回建筑使用基于泰文 328 Arduino 平台上的嵌入式微型控制器线追随者。有 5 光电二极管作为传感器读取使用 arduino。要追溯到的行被假定为黑我颜色和背景必须是白色。因此上面的白色部分传感器会产生较高的值作为输出，上面的黑色部分要低。现在逻辑写入驱动电机，控制使用 IC L298 每个电机的转速。

The AGC is a smart programmable gain amplifier (PGA). The amplifier gain is adjusted based upon the input signal level so that the output is at a specified Target Gain. The AGC can be configured to be either a mono or stereo input / output component. For illustration purposes, the following discussion will highlight the stereo configuration.

与单极步进电机不同，双极步进电机每相只有一个单绕组，没有抽头。 为了反转磁极，绕组中的电流需要反转，这意味着双极步进电机驱动通常更加复杂并且通常需要H桥排列。 由于没有公共端，每相有两个引线，典型的两相电机会有四根引线。 尽管双极电机通常驱动更加复杂，但它们确实具有它们的优点，因为更好使用的绕组，双极电机比同重量的单极电机更强大。 这是因为单极步进电机在相同空间中有两倍的导线量，并且在任何一个时间只能使用其一半，这意味着单极电机仅有约50％的效率。(Unlike the monopole stepper motor, the bipolar step motor has only one single winding per phase, without a tap. In order to reverse the magnetic pole, the current in the winding needs to be reversed, which means that the bipolar step motor drive is usually more complex and usually requires a H bridge arrangement. Since there is no public end, each phase has two leads, the typical two phase motor will have four lead. Although bipolar motors are usually driven more complex, they do have their advantages, because the better use of windings and bipolar motors is stronger than the same weight monopolar motors. This is because the unipolar stepper motor has two times of wire quantity in the same space, and it can only use half of it at any time, which means that the single pole motor is only about 50% efficiency.)

利用arduino控制超声波模块测量距离数据

说明：  DS18B20 温度传感器相关库文件，还需要DallasTemperature库文件配套使用。(DS18B20 temperature sensor related library files, also need Dallas Temperature library files supporting use.)

说明：  Arduino_STM32-master

Arduino遥控格力空调。你可以用Arduino单片机和一个红外发射管就可以开关自己家里面的格力空调。如果是其他空调，你可以根据需要将编码改掉就可以了。
