Roadmap

2. USB3. NFC

1. Arduino primer

4. WIFI

Arduino Primer

Arduino is an open source hardware prototyping platform

Arduino Primer

What makes it special?

• Easiness to use• Modularity• Awesome community support

Open Accessory Protocol

Google’s protocol for usb communication with third party devices

Open Accessory Protocol

How does USB work?

Open Accessory ProtocolHow does USB work?

• Host• Slave

Open Accessory ProtocolHow does USB work?

• Host • Slave

- Is the power source

- Keeps track of connected devices

- Initiates the data transfer

- Communicates with host via endpoints

- Can draw power from host

- Describes it’s protocols & capabilities to the host
