Arduino开发之Digital Push Button(Red) 环境搭建: 1. Arduino UNO R3开发板, 2. Arduino IDE。 我这里使用的是1.8.3。可以在https://www.arduino.cc/en/Main/Software下载并安装。 安装好之后,桌面会有如下图标。 示例开发: 1.连接设备。 本例中我们以Analog Linear Temperature Sensor(DFR0023)并结合DFR...
Arduino uno Breadboard LED 220 Ohm & 10 KOhm resistor Push button Step 2: The Circuit When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton, so the pin is connected to ground (through the pull-down resistor) and we read a LOW. When th...

For the bluetooth connection the Leonardo comes with a hardware serial interface (RX/TX). With other Arduinos like the UNO you may have to switch to a softserial. For this the code has to be adapted accordingly. Why use audio cables?
