This lab aims to team member’s enhance the ability of using Arduino software of controlling the AEV.
The group installed the lab equipment successfully. While installing the lab equipment, one of the member connected the motor wire in a wrong direction. Fortunately, before testing the overall equipment, another team member discovered this error and fixed it. The point is that the same color wires should be attached with each other. If the direction of wires is wrong, it may result in irrational running behaviors of the vehicle or may damage the electric motor.

And the team members have been familiar with basic control functions of Arudino software and have a good knowledge of controlling the electric motors. In this process, the team discovered that when the electric motor starts running, there would be a delay. And the team indicates there are three possible reasons for this delay:
- Electrical signal between Arduino and motor may be delayed at very beginning of the running.
- The battery may need to be charged.
- There may be some force friction in the motor due to the mechanical issues or lack of lubricating oil.
