I hope you guys have a wonderful holiday season.
I have purchased a pulse sensor (http://pulsesensor.com/), and have successfully received values from it. The next step I want to take is connecting it to a Bluetooth module (HC-05), so I can transmit values to an Android app (Amarino library).
I am pretty clueless about how to connect Bluetooth to Arduino; On the hardware side, I have connected the HC-05 module to the sensor. IS there any code I must add to the sensor code to initialize the module, and what is the command to send data? Thanks in advance.
