We need to develop a software to control how much time a Kart (Go Kart Racing) stays in pit. Each time must be on the pit's at least a determined time (lets say 3m or 180s)
When the Kart arrives at the pit-lane entrance there should be a computer equipped with a Bar-code Scanner so the Kart (and the driver) will be identified and the counter starts (of the three minutes). This system must be able to monitor at least 30 Karts. On a second computer we must have a screen showing the time spent on the pit's of the 6 Karts more close to the determined time, in this example 180s. When one Kart is more than 180s the timer must disappear.
The software must also register how many times in a race a kart and a driver entered the pit-lane.
