Lap Counter Project

3629 Views 10 Replies 10 Participants Last post by  -Sy-
Hello all,

I am a Slot car racer, and I am building a lap counter for home use for my GCSE electronics project. To help me with researching this project, I would like some info on what the most important aspects are, so if any of you can spare a minute to help, I would appreciate it greatly.
Please number the following aspects 1-12 in order of importance:

1. Ease of portability
2. Ability to count up to set number of race laps and then switch over to count down mode for the race
3. Size/compactness
4. Sound at the end of the race to signal the race is finished
5. To be mains powered
6. To be battery powered
7. Should the counter be a box at the side of the track
8. Should the counter be a bridge type over the track
9. Should the counter be mechanical and then be fixed to the underside of the track
10. Should an Infra Red non-contact sensor be used
11. Should individual lap times be recorded
12. Should the best lap time only be recorded

Please answer and feel free to add any general comments as well.

Arduino is good, the initial cost is low, however if you want to make it do anything serious, then the add ons can make it expensive....I've been playing with one for several weeks...good points IDE is free, buggy but free...downside no online debugging facilities...I've now gone back to PIC microcontrollers, they are cheap, well featured and there are lots to choose from. I bought the easypic 7 dev. Board and IDE for c from mikroelectronica...good price and a lovely development system, with full debugging support.

Timing depends on Pic chosen and can easily time to millisecond resolution and higher.
