Chapter 2 – Brain Units
2.1 Brain units
Some of the input units can have their own "brain". The NeuLog sensors are such
brain units. They send to the control unit, upon request, processed data such as:
temperature (
o
C or
o
F), light intensity in Lux, distance in meters, etc.
The output units can also be brain units. For example, units that control the motor
speed and direction, lamp intensity, servo motor angle, etc.
These brain units are connected in a chain to the main control unit, which
communicates with them through messages.
Every brain unit has an ID number. Every message from the control unit starts
with ID number. Only the brain unit with this ID number interprets the message
and executes it.
This system construction is the way modern systems are built, and has important
advantages:
1. It creates a system with much less wires. The wires go from one module to
another and not from all modules to the control unit.
2. This kind of system can easily be changed and expanded, and does not
depend on the control units number of inputs and outputs.
The experiments in this chapter use the following brain units:

Neulog light sensor (NUL-204)

Neulog sound sensor (NUL-212)

Neulog motion sensor (NUL-213)

Neulog magnetic sensor (NUL-214)

Brain tracking unit (SNS-101)

Brain IR transmitter (SNS-160)

Brain gripper arm (SNS-167)
