Success at last!!
Thanks to the code Bryan helped us write, and some soldering skills from Holly and I, we have built upon what we have got so far, and today we were able to get the HRMI to communicate with the arduino! In short, we successfully asked the HRMI for a heart rate, the arduino calculated what “track” we should then be at, and moved the MP3 player to the correct track number! I was wearing the heart rate monitor, and it was playing different tracks as my heart rate changed. We were so excited and happy that it worked that my heart rate was increasing and the tracks were changing accordingly! It was brilliant, believe me.
The image I’ve posted is a screen shot that shows ‘proof’ that we got it to work. We are just a bit scared that once we try to transfer everything from the breadboard to the lilypad that something might screw up. So I’ve ‘documented’ the achievement as best I could.
In order to get the HRMI to talk to the arduino, we had to change some of the settings on the HRMI that came as factory default (this was the key). We needed to install the OPO jumper so that the HRMI could operate on I2C signals. This meant that we also had to uninstall the SJ1 jumper.
The next step is to move everything from the breadboard to the lilypad, which is, as I mentioned, the scariest part.
Cross your fingers for me**
Good luck with the switch over! Don’t mess up my code!
awesome work, awesome colour choices — congrats!

Hi,
This is so cool. I am a technologu entrepreneur and have been working with wearable remote healthcare/wellness sensors. I have developed something really cool that you would probably be very interested in. Feel free to send me a quick email and we can get in touch and have a quick conversation.
Thanks for all your incredbile work. Great to read about and follow.

hi, i’m a student from USYD, working on the Heart rate interface & Arduino at the moment as well. but i tried to use the sample coding from dan julio’s web. but seems it didn’t work. so confuse with the sample code now. did you use AnalogIn pin to connect the HRMI to the Arduino? i follow the instruction in the sample code, which install the OPO jumper & uninstall the SJ1. the status LED of HRMI is flashing to send signals. but Adruino still didn’t print any data. is it anything wrong in the sample code? Could you help?
sincerely
Kerry Lin
