The C is just a simple push button, besides of rotation push down the knob will switching between scanning mode or make a selection on setting mode. There are many kinds of rotary sensors there. We are to use RE111M for our PCB on version v2.12. To make our Arduino Walkie Talkie ...
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...

在工作中或者日常开发中，我们使用 Git 进行开发上传至 Github 等托管平台，有些时候，我们必须把某些文件放到 Git 的工作目录中，但是又不能提交它们，比如保存了数据库密码的配置文件、ide 的配置文件等等，不然每次查看状态都有未监视的文件Untracked files ...，有强迫症的话肯定不舒服，而且每次都要取消掉这些文...

When the Reset (ENABLE) button on the ESP32 module is pressed it starts counting seconds, which are displayed on the serial monitor. The count continues until the push button we attached to our module is pressed. It can be reset to start again. 1 2 3 4 5 6 7 8 9 10 11 12 13 ...
其中有一些还安装了一个能够在轴上按的button,就像音乐播放器的控制button。Some of them are also equipped with a pushbutton when you press on the axis (like the ones used for navigation on many music controllers). 它们的精度多种多样。有每圈16步到1024步的各种。价格也从2到200欧元不等。
这里的STK500v2 bootloader会用Port B4 (即Arduino板上面的Digital Pin 12) 决定行bootloader定系行application ﹐所以reset时如果Digital Pin 12系Low就会入bootloader(板上粒LED会长亮) ﹐如果系High就吾行bootload而直接行application code﹐我建议加枝10k ohm pull up resistor同一粒 pushbutton晌 Digital Pin 12...
