This unit introduced us to "phases of development", where a finished product is achieved in several parts or phases. Our first phase was to acquaint ourselves with interfacing the Arduino Uno and a servo. Our second phase was coordinating an HC-SR04 Ranging Sensor to provide input used to control a servo via Arduino Uno. Our third phase is the final phase of this development cycle resulting in a finished product with two HC-SR04 Ranging Sensors, a servo, and an Arduino Uno.
Fork and complete the schematic shown below which will be used in phase III for Generation One Parking Garage Gate.
Parking Garage Gate Generation Two
New Feature: The car driver can push a button causing a virtual ticket to print out in the Serial Console and causing the gate to open.
Phase I of Parking Garage Gate Generation Two involves getting acquainted with interfacing the Arduino with a push button component. Unfortunately, my order of simple push buttons was cancelled and we must share a 5 key keypad component instead. Here is a link to a page where you can read up on this new component.
We will use this time library to keep track of the time for our new parking garage gate.
