Midterm- birthday card Arduino combination code

Transcription

1 William Kasurak Midterm- birthday card Arduino combination code Initially for this assignment I wanted to create a jukebox combination lock that allowed the user to set a one pin combination for the combination lock portion of the code and then assign a different song to be played depending on which of the 9 numbers the keypad I bought for the assignment. The Arduino would be housed in a cardboard jukebox encasing and have space for a speaker, the keypad and a 2 leds; this way when the code was entered through the pad after the code had been declared correctly a green led would blink and then a song would play through the speaker using tones however I was not able to quite get the syntax down in my sketch so that the code could be changed from within the sketch, because I could not find the resources to help me get the right syntax for a char* array to include variables that could be declared in the loop portion of the sketch! This caused me to move onto my second concept working on the limitation of only being able to code a combination lock that I could change the combination too through editing the sketch in two places, one to establish the passcode and another to establish the length of the code so that when all the digits were entered correctly in sequence an if statement could be triggered setting the lock to an unlock state. I decided to instead use all the same components as in my jukebox concept to create a new piece that functioned as a riddle for the class. I wanted to create a piece that indirectly invited all the class to celebrate my birthday with me on our trip to new york together in march as it will take place during the trip. So I set it so that the pin for the pass code would be 8 numbers long, leaving enough for me to set the pin as my birthdate in dd/mm/yyyy format. The keypad would now instead be inlayed into the inside of a card that I would present to the class during the critique, the card would say you are all invited to attend a secret event in NY on one of the days of our trip with me if you can guess the date 21 years ago that it would have happened on if we went then. The class would probably solve the riddle quickly seeing as how they know my age approximately and there are only a set number of days we are on the trip. When the code is entered correctly the first 7 notes of happy birthday, confirming the event to be my birthday if the code was entered correctly coupled with the green led shining. A simple on state for a period of 5 seconds of the red led would occur during which input to the keypad would be blocked would occur if the wrong combination were entered. Unfortunately due some rotten luck, even though I spent over 15 man- hours over the week/weekend on the assignment and couldn t get my keypad to work halfway through the work so unfortunately I will not be able to show a functioning version of this in class.

2 Here is the circuit diagram for the final version For Whatever reason Github won t work for me yet again this week so I ll include my code here it comes in two parts the firs part is a library I had to input into a tab in the Arduino sketch naming it pitches.h

9 Here is the mockup sketches I did for both versions of my concept. and here is the final version ( no video available of working version because of keypad (keybad,morelike) failure!)
