Hi,
I am new to Arduino IDE software and I have problem coding for RedBearLab Blend Micro V1.0.
I need to convert continuous analog signal (ECG signal) to digital signal and transmit the digital signal via bluetooth to arduino uno (which will be connected to the computer with usb cable).
May I know where can I get basic coding to do the above function?
Thank you!
And what exactly is "RedBearLab Blend Micro V1.0"?

Blend micro has both a micro-controller unit and a blue tooth component.
It seems to be an Arduino compatible board that includes a Bluetooth module.
What is the peak-to-peak voltage range of the ECG signal and what is its highest frequency?
If the voltage and frequency are within the capability of the Arduino you could use analogRead() to digitize the signal.

The peak-to-peak voltage range is 2V and the highest frequency component is 40Hz with noise approximately 10mV-100mV.
On that basis there should be no difficulty using the Arduino ADC to digitize the signal.

Does that mean I can actually use the example code in Arduino IDE to digitize the signal?
How can I incorporate coding for Bluetooth transmission to the Arduino uno connected to the computer?
ReadAnalogVoltage.ino (761 Bytes)
That is avery simple program, but it represents what you need to do. You need to decide how often you want to take samples. There is a lot of theory about that which has nothing to do with Arduinos. I think 2 times the wave frequency is considered a minimum, so may 4 times would be a suitable balance between accuracy and data volume.
Treat the Bluetooth issue as a separate project to start with. Get your Bluetooth device and learn how to send "hello world". In fact Bluetooth is just serial by wireless.

Now tell me how long did you google for.

The Silicon Chip reference is because I get this electronics magazine.
