Hi there! Okay so here is my story. I'm flying up to see my fiance for her birthday and I really want to make her something special. So! I decided it would be fun if I could make her a digital circuit design! Here's how I want the project to go.
Her favorite number is "333". Basically, what I want to do is I want her to be able to turn on the device with a power switch. Then, I want there to be a start and reset button or switch, which ever is easier. Now, she'll turn on the device and then whenever she pushes/switches "start", basically I want there to be 3 "7-segment displays" starting at 000 and ending at 333 counting up in increments of 1 (i.e. 000 001 002 .... 220 221 222... 330 331 332 333) pretty fast, I'd say I'd like it to be about 10 seconds long, whatever is possible. Then once the 333 is displayed, I want the display to freeze on that number and then I want another display made of LEDs or something to light up and say "I Love You". And then of course, if she wants to see it again she can reset the circuit to it's initial state and run it again.
I did take a digital circuit class about a year ago, and currently don't have the time to go back and recall everything (Taking 12 hours this summer at college). But I have been around the block so I'm a little experienced. So basically, I have everything in my mind that I want. I'm not sure at all where to begin or what parts I'm going to need. I'm thinking since i'm using a counter, I'm going to need flip-flops. Any help in this design will be extremely appreciated and helpful for making her birthday gift special and unique.
Thanks!
