Use the Rasp Pi to log data from bicycles and motorcyles
Costs
Table 1 provides an example of the expenses involved in the setup chosen by one of the groups. The largest expense for all groups proved to be the bicycles and the motorcycle, but neither is included in the statement. Anyone who wants to work on a similar project might already have some of the electronic components, so the costs could vary from project to project.

Conclusion
The end result of these projects looks to the future of what is possible and what makes sense. Creating the switches with a breadboard was a good idea for a prototype; however, it would be an even better idea to put the board and switches in a mountable housing to provide some protection against the elements and other dangers on the road.
In terms of potential applications, the projects presented here have practically no limits. For instance, it would be possible to adapt these setups for use with double-axle vehicles such as race cars.
