Ever thought of controlling any electronic devices with your smart phone ?Controlling your robot or any other devices with your smartphone will be really cool. Here is is a simple and basic tutorial for interfacing Bluetooth with arduino
Step 1: Things You Need
Hardware
- Bluetooth Module HC 05/06
- Arduino
- LED
- 220Ω Resistor
- Android device
Software
- Arduino IDEArduino IDE
- Android Studio (Not Really required I will provide the android application :D)
Step 2: Watch How Does It Works ?
Watch the video tutorial
Step 3: Let’s Start Building
The circuit is so simple and small , there is only few connection to be made
Arduino Pins___________Bluetooth Module Pins
RX (Pin 0)___________________TX
TX (Pin 1)___________________RX
5V_________________________VCC
GND_______________________GND
Connect a LED negative to GND of arduino and positive to pin 13 with a resistance valued between 220Ω – 1KΩ. And your done with the circuit
Note : Don’t Connect RX to RX and TX to TX of Bluetooth to arduinoyou will receive no data , Here TX means Transmit and RX means Receive
