ST / Mbed 2 deprecated Seeed_BlueBot_demo

Nucleo board with Seeed bot and bluetooth shields demo.

Dependencies:   BluetoothSerial SeeedShieldBot mbed

This code shows a simple application composed of a Nucleo board, a Seeed Bot and Seeed Bluetooth shieds:

This picture shows how the three boards are stacked together:

You will need also to use an application on your phone to send Bluetooth commands and to be able to control the Bot shield. We have used the Bluetooth spp tools pro Android application.

Look at this video to have more details about this demo:
