Hi
I'm brand new to this, so be kind!
I've been asked to make a timing system of the F1 in Schools club at the school I work at. The students design and make a small model racing cars are powered by CO₂ cartridges and are attached to a straight 20m track by a nylon wire.
I was wondering if anyone had done this or something similar using Arduino as it was recommended to me?
I've seen lots of timers that use the same start and finish gate/sensor, but am struggling to find something that uses a sensor at the start and a different onm at the finish.
Thanks in anticipation for all your help and understanding

Use such a project having a start timer setup. Then add a stop timer sensor using another digital input pin. Save the srart time and the finish time. Then cam ulate finish time minu start time
I agree. Any lap timer, which we assume uses one sensor to both start and split or finish laps should be amenable to the modification suggested - a second sensor which only needs to be able to do the same thing.
So where the code you find reads one sensor and does or does not do anything, simply use both sensors and if either one is active, do the right thing - start if not timing, finish if the timer is running.
Get the single sensor lap style project working with as little tinkering with the code or hardware as you can manage.
We here if that part doesn't go so well.

Can you post drawings / pictures of your track with dimensions? Meters / cm or feet / inches? Size of car and construction material? Estimated speed?
