NDS3 distance scanner - Nibo2 expansion module

The NDS3 expansion module additionally gives the Nibo2 the ability to measure exact distances to obstacles in a range from 10 cm to 80 cm. The sensor can be rotated by 180 degrees by a servo. This enable, for example, the exact orientation and the distance to a wall to be determined. Maps of the surroundings and a localisation can also be achieved by clever programming. The expansion module has an Atmel ATtiny84 a separate microcontroller for data processing and communicates with the Nibo2 via the I²C interface. The ATtiny84 can be programmed via the 6-pin ISP interface. Personal circuits can be built on an additional user area. 6 signals on the ATtiny84 and an additional 4 signals on the ATmega128 are available to control the personal circuits.
