Unit 3 Lab 2R
Metro Access Activity
In this lab, you will build a fully functioning metro turnstile that scans a rider’s Metro Card, stores the card holder’s metro account information, and then opens the turnstile to allow entry.

Light Sensor
Light Sensor
A Light Sensor responds to the intensity of light level with an increasing signal voltage. The Light Sensor can be used to make a decision based on a set threshold between 0 and 100. 0 refers to no light (dark) and 100 refers to very bright light.
Position Servo
Position Servo
A Position Servo will turn to a specific angle from 0 to 180 degrees and could be used to open and close a door. A Rotation Servo will rotate continuously and could be used to spin the blades of a fan.
Simulating Metro Card Scan

Validating the Metro Card
Validating the Metro Card
In this section, you will create a list of riders using the Contact List you have already created, assign an expiration date to each metro card, and develop code that checks whether or not the metro card is valid and has not expired.
