Below is a list of resources to be used in the initial phases of building the Carddio prototype.
| 48HoursLogo | A project is always more fun when you have a nice logo to rally around. Our experience with 48HoursLogo and Girly were very positive. |
| Pulse Sensor | This Arduino compatible device measures pulse using light applied to the fingertip or earlobe. It's not as good on the wrist, but useful for testing Arduino and Processing code. |
| Dia Portable |
Dia is a tool for making diagrams. For this project, we will use Dia Portable to make the initial circuit diagrams. |
| Red Bear Lab | Bluetooth 4.0 (BLE) Arduino shield with apps for Android and iOs. |
| Processing | Easy to learn and use programming language that works well for prototyping and graphics. |
| Arduino | Prototyping microcontroller that is ideal for IoT experimentation. Hardware called Shields can be connected to add functionality like BLE. Grab a breadboard and change the world! |
| GitHub | Open source software development and version control platform. Carddio will be posting circuit diagrams, Processing code, etc. as it is developed and tested. |
