Light sensor
This sensor allows mOway to recognize the light intensity that enters through a
small half moon-shaped opening on the top part of the chassis. Since it is facing forward
it enables it to detect where the light source is located and to act accordingly.
The output of the AVAGO APDS-9002 sensor is connected to the analog port of
the microcontroller so that with a simple reading of the ADC we can register the light
intensity level and any change in intensity levels based on the last reading

Expansion connector
This connector allows the mOway to connect with any commercial modules or
electronic circuits the user may choose.
As shown in the above table, it is possible to connect commercial SPI devices. On
the other hand, the RF BZI-RF2GH4 module available in the market is totally
compatible with mOway and with specific libraries. This module enables the mOway to
communicate with other robots and with a PC via the RFUsb. With this module it is
possible to create complex collaboration applications without having to worry about
complicated wireless communications.
