In week four, the flex sensors were arrived and all previous sections could be connected. All the action modes of car was completed and tested. Moreover, the test of employing Bluetooth to control the car was successful, which means most work of car part was completed.  Working Details Motor Group: Before the lab, we have spent some time at home to writing the codes of the nine running modes, and each of them were tested to ensure they are working.  The video of testing is shown below.  However, there is a problem that the buttery could not supply enough voltage to run the motors and arduino at the same time. Therefore, a portable power bank was employed to supply power for the car, but it is too heavy for the car. Consequently, another power supply should be found. Video of testing In the morning of the lab day we were trying to connect the arduino and phone. At this time, the phone can find the Bluetooth. However, there are still some bugs on it, whic...

This week, a fter discussion, the work plan of two groups in week two was decided. For motor group, they should complete the library files of controlling part, and test them to make sure they work. Furthermore, they should spend some time too study the working principle of Bluetooth on arduino. For Flex Sensor Group, they are planned to test the resistance of flex sensors, and study the work principle of flex sensors on arduino. In addition, if they have enough time, they should complete some codes of Bluetooth and flex sensors.  However, the flex sensors still not available and we can't test the resistance and work principle of them this week. We had to work on the codes of Bluetooth and flex sensors first. Working detail Motor Group: In the morning of the lab day in week three, the work is boring. Actually, we spend almost the whole morning in debugging, because it is the first time for us to write the library files for arduino. There were some data type...
