Hello all,
I have designed a DIY project to acquire ECG signal now i have to transmit it through Bluetooth module HC-05. I have connected the analog output of my DIY ECG model to the A0 of analog input of my arduino R3 development board. I have connected the bluetooth module HC-05 correctly now i am cofused how the analog signal be converted to digital for the transmission through HC-05 as I am not much familiar with the arduino coding. Please help me out here.

Before going on to such an advanced project, study the simple examples that come with the Arduino IDE.

Learn to read the analog inputs and print the data on the serial monitor.

Then learn how to send data by Bluetooth. When all that works, you can put the two together.
