| `pinMode(buttonInput, INPUT_PULLUP);` | 您需要使用 INPUT_PULLUP 作为按钮开关的 pinMode()函数中的第二个参数。 | | `int sensorVal = digitalRead(buttonInput);` | 开关的值被读入每个循环的变量中。 | | `if (sensorVal == HIGH) {``digitalWrite(LEDOutput, LOW);``} else {``digitalWri...
将文件另存为项目文件夹中的gpio_button.py。如果使用终端窗口,请执行以下操作:导航到您的项目文件夹。在我的 Pi 上是$ cd ~/TRG-RasPi-Robot/code。 类型touch gpio_button.py。 类型idle3 gpio_button.py。这将在 Python 3 的空闲 IDE 中打开空文件。 输入以下代码: # GPIO example using an NC-SR04...
The function starts by reading the touch point data and determining the touch strength. When the strength exceeds 555, the touched variable is set to true. If the code detects a touch input, the function checks whether the repeat button is visible. If it is hidden, the calibration is ...

Run the .exe and move your mouse, the software will automatically detect the position of the mouse. If you press the left button of the mouse, the textbox will show the event. You can see the code in the attachments ordownload the demo here. If you want to DIY this demo, you need...
you install an Arduino library. You should notice that almost all of our library was stored atGithub. We will provide Arduino libraries when a product need a library, likeCAN-BUS Shield V2. But for some other simple products, there is no need to write a library such as Grove - Button....
A recent implementation of this menu system uses the Nextion touch-screen displays. These displays come with some nice tools for designing buttons and sliders and using images as backgrounds. The Nextion tools compile the local touchscreen code into a file that can be copied to an SD card, an...
