hi to all
i'm very noobie @ programming arduino world. Apologise for my English.
i am trying to make a project to back up a drag race timing system with mega 2560 board with dual lcds, some leds as starting tree signal and switches to indicate that the vehicles have pass the finish line.
i have can only to achieve it with one lcd and a single start stop reset button.
i have copy paste all the sources on the net so it came like the attachment racetimer.ino
i also has upload on youtube for trial the system: indonesian drag racing association prototype timer tes 1 - YouTube
now, after all working normally.
i would like to add two more switches to indicate finish lines has been passed instead of using one switch for start, stop and reset and start new timer.
i also would like to add more timer on lcd display instead of only having one running stopwatch, both will show in top and bottom cursor instead of only have 00:00:00 (minutes:seconds:millis), need to change it into for example: top cursor "left 14:100" (seconds:micros) and bottom "right 14:300"
would it be possible to add another 16x2 lcd to display only the result? the first lcd showing the stopwatch action for both lanes and the second lcd showing only the result of the race.
would anyone can help how to modify the setup and sketches?
