Arduino HC-05 (Bluetooth) Interfacing
In this post we will access Arduino over Bluetooth either through ur PC or Android device. This will be useful in case when you have sensors interfaced to ur arduino board and want to send this information to ur Mobile. Things needed to do this experiment: 1. Arduino Uno 2. HC-05 Connections: 1.Connect TX of HC-05 to TX of Arduino 2.Connect RX of HC-05 to RX of Arduino 3.Connect GND of HC-05 to GND of Arduino 4.Connect VCC of HC-05 to 5V of Arduino Power up the device either by connecting USB or a battery. Now you can scan this on your PC or Android device to see whether your device is listed out. For example in Ubuntu I can run hcitool scan and it lists out all the Bluetooth devices. Now you can see a device with name HC-05 in the list. This means your HC-05 is working properly. You can also check the same on your Android device. Now you have to pair your Ubuntu Bluetooth with HC-05. In order to achieve this: 1.Go to Bluetooth Icon, and cli...
