前两天发布的一个用Arduino制作的RC控制器,有朋友留言说对这个项目的制作过感兴趣,所以本期我把制作的详细过程与大家一起分享。 第1部分—发射机原理图 下面是这个项目的示意图,其中包含所有连接和组件值。在下面的完整部件列表中也检查这个项目所需的所有内容。确保你把降压转换器设置为12.6V和3.3V,然后再连接到...

ARDUINO LILYPAD SWITCH User Manual Description:This is a simple ON/OFF switch for the LilyPad. When the switch is in the ON position it is closed and when it is in the OFF position it is open. Use it to trigger behavior in your programmed project, or to turn LEDs, buzzers, and ...
leaving us with a more compact microcontroller board which we'll secure with 4 tiny screws onto the underside of the top cover followed by the mode button with its cap and holder screwed into place. Right next to it, we'll insert an active piezo buzzer for sound indication. Then we can...
whereabouts through hearing. After that, let's click “WRITE” and then “READ” to save those changes. Now, when flicking on the arm switch, the drone should allow for its motors to spin up when increasing the throttle. Also, the buzzer should beep when the corresponding switch is flick...
You can use a rotary encoder with push button function or three plain push buttons. The addition of a complete key matrix up to 4×4 buttons is also possible. For acoustic feedback, a piezo buzzer can be added.The current implementation supports direct connection to IO pins of your Arduino...
在本套件中,Grove-Buzzer是一个无源蜂鸣器,所以需要一个交流信号(AC)来控制它。这就引出了下一个知识点,如何用Arduino产生方波(交流信号)! 一个简单的方法就是使用PWM。 Seeeduino上有六个数字引脚,上面标有“〜”符号,表示它们可以发送PWM信号:3、5、6、9、10、11。 它们被称为PWM引脚。
There is a pretty huge amount of code in this Sketch. Just press the “Copy” button on the top right of the code text field for it to automatically highlight the whole code for you. /* Arduino Mario Bros Tunes With Piezo Buzzer and PWM ...
