HI,
I am new to Arduino and need a little help. I have already built a few timers for work(chemical lab performing chemical permeation test). Anyway, I video record city council meetings in my area (on the side). Normally I use a stopwatch and write down which camera I want to "cut" to in editing and jot down the time. My goal: built an Arduino stopwatch that, when button 1, 2, 3 or 4 is pressed, will record the time AND which button pressed (kind of like a "lap" function on a stopwatch).
A meeting can take anywhere from 10 minutes to 4 hours (sometimes without any breaks). The last meeting I recorded lasted 2.5 hours and I noted 39 "cuts" for editing. Microseconds and milliseconds are unnecessary, only hours, minutes and seconds. I have been researching it, but quite frankly I'm swamped with another project at my day job (a robot to shoot gas standards of chemicals, which I am almost done with, which is just another timer with 6 more functions).
I am imagining it would involve a digitalwrite to a folder location, a stopwatch/ timer library, one start button, one stop button, 4 or maybe 5 buttons to denote which camera, small lcd to display the stopwatch), and possibly a microSD card breakout board to store said data (although arguably a four hour meeting may only contain 80 to 100 lines containing the following type characters: "c2 - 3:10", for example, where c2 would indicate camera two and 3:10 is three minutes and ten seconds into the meeting as to when I need to cut to camera 2). I was thinking about using a microSD card so maybe I could pull the card out, and view it in notepad while I edit and it look something like:
c2 - 3:10
c1 - 4:35
c2 - 10:08
c3 - 15:43
etc....
Please keep in mind that I am not asking for anyone to write the code for me, just a littel advice on which functions I need to incorporate, libraries, etc
Any help would be greatly appreciated.
