Distance sensing with ultrasonic sensor and Arduino. Bluetooth Serial initialization works exactly the same way regular Moxule communication works, we call begin method with the baud rate. The wiring is really straightforward, no extra components are needed.

Reading through the docs is, again, encouraged, as we will use very similar code to drive our JY-MCU module.

First we include the library and set our RX and TX pins. Once we turn on Arduino, a red light on Bluetooth module should be flashing continuously.

For transmitting information through the module we will use the default SoftwareSerial library. If there is any data received by the bluetooth module, send it over the regular Serial connection to our PC.

For Apple devices there should be something similar on the App store as well. Simply connect the 4 pins to blustooth Arduino board. Considering how ubiquitous Bluetooth is most smartphones and laptops have itit will turn out to be extremely useful in our future projects.

If you have an Android device, there is this Blue Serial app for testing serial communication over Bluetooth. Here is the datasheet for the main module: Measuring temperature with DS18B20 temperature sensor. Last time we looked at measuring temperature using a digital temperature sensor. Once connection is established, that pot light will stay on constantly.

Easy Arduino Bluetooth Communication with JY-MCU Bluetooth module

It is already arduio with Arduino, so no further downloads are necessary. If PC sends information via Serial, then we send that information over via Bluetooth. Here I sent some information from my PC to the phone and vice versa: Only two pins to drive the module, other than that the interface is exactly the same as serial communication wieless PC via USB. So we have several modules generating data, would be great to be able to access that data remotely.

If you open up SoftwareSerial constructor docsSoftwareSerial constructor is defined as such:. It also provides some information on how to change the baud rate, device name and passkey, so make sure to check the data sheet.
