如下图所示,模块有一个2位拨码开关,1号开关LED Off是LINK灯的开关,可以关闭LINK省电,拨到ON为开,拨到1端为关;2号开关AT Mode是AT命令模式开关,拨到ON进入AT命令模式,拨到2端退出AT命令模式。 STEP 3: 连接到USB to Serial模块 1、设置DF-Bluetooth V3蓝牙模块需要借助USB to Serial模块,如下图所示,将蓝...
brakeOn(); } else { brakeOff(); } } } //end of code then attach your led(s) to pin 13 and Gnd. Thank you. which code is to be used # bluetoothcar3.0.ino.ino or # bluetoothcar4.0.ino.ino
InstallBluetooth Serial Monitor Appon your smartphone Copy the provided code and open it with the Arduino IDE, then upload it to your Arduino board. If you have trouble uploading the code, try disconnecting the TX and RX pins from the Bluetooth module, uploading the code, and then reconnecting...
For a brief introduction to the ESP32 with BLE on the Arduino IDE, we’ll create an ESP32 BLE server, and then an ESP32 BLE scanner to find that server. We’ll use and explain the examples that come with the BLE library.To follow this example, you need two ESP32 development boards...

Command your Drones to take off Tell your Smart Lights to Dance Ask your Robot to bring you a drink Or keep it simple and turn an LED on with nothing but your voice Very easy-to-use GUI Automatically searches for Bluetooth Devices and Bluetooth-enabled Arduino boards or boards with a blu...
In a previous post I showed how to connect an app inventor Android app to a Bluetooth module connected to an Arduino to control an LED. See Turning a LED on and off with an Arduino, a HC-06 and Android A few people have asked how to make it so that the app auto-connects to the...
In first example you could only control the LED from the Android app, here we extend the example so that we can also control the LED at the Arduino side. When the LED is turned on or off by the Arduino we want the button in the app to update to show the correct LED status. The ...
