CPU: Central processing unit is the brain of AUTO MODE METRO TRAIN. It processes all inputs and gives corresponding outputs.
MOTOR: Here we use two types of motor-
- To run the wheels
- For opening & closing door
OBSTACLE DETECTOR (IR):
It uses IR receiver and IR transmitter . If any obstacle is found in front of train , the intensity of IR sensor increased, abruptly and obstacle is detected.
It uses magnets on the track near the station , when train passes through this track , train sense it because of reed switch and it display information like “welcome station- A OR previous station- B”.
