此内置函数将返回字符串输入的第一个字符,该字符将与上表中的指令之一相对应。 请注意,通常,每次要将新的草图上传到Arduino时,都必须断开HC-05模块的连接,但是由于我们使用的是Arduino Mega,就有了四个单独的硬件串行端口!因此,我们只需要将蓝牙连接到剩余的端口之一就可以同时进行这些操作了。 需要记住的另外一件...
Arduino开发板有多种型号,如Arduino Uno、Arduino Mega等,选择哪种型号取决于项目的需求。 I-BUSRC开关也有不同的类型,包括单键、多键、编码开关等。 应用场景 智能家居系统中的灯光控制、窗帘控制等。 工业自动化中的设备远程控制。 模型飞机、遥控车等遥控玩具的控制。

Similarly, if you are using Arduino mega pins 20 and 21 are SDA and SCL respectively. Arduino Digital Clock using DS3231 Pi Module circuit diagram So, connect the SDA or D pin of your RTC module to the SDA pin and the SCL or C pin to the SCL pin of your Arduino board. The Vcc ...
The Arduino Mega is perfect for projects requiring a lot of input/output pins, for instance more complicated robots, 3D printers, and other sizable automation tasks. When you need to interact with a lot of sensors or other devices, or when you need to control a lot of different actuators ...
Arduino Mega RaspberryPi3 三、代码 & 运行 RF24库中自带的GettingStarted例子非常方便,其代码包含发送端和接收端两种类型, 默认为接受模式,输入T时切换为发送,输入R则切为接受模式,并有简单的超时判断。 为了易于理解,可简单修正代码,让接收端返回一自增数字。
