What Is CAN Controller Area Network
Invented by Robert Bosch GmbH in 1980 for automotive applications
Asynchronous Serial Bus Simple 2-wire differential bus Absence of node addressing
• Message identifier specifies contents and priority• Lowest message identifier has highest priority
Non-destructive arbitration system by CSMA with collision detection
Multi-master / Broadcasting concept Sophisticated error detection & handling system

ULTRASONIC SENSOR
•With 2.5V - 5.5V power the ultrasonic provides very
short to long-range detection and ranging, in an
incredibly small package
• The LV-MaxSonar-EZ1 detects objects from 0
inches to 254-inches (6.45-meters) and provides sonar
range information from 6-inches out to 254-inches
with 1-inch resolution.
