Introduction to Coding

In this lab, the main task was to operate the model AEV using the Arduino functions. We had to build the sample AEV before coming to this lab. After installing the functions into the Arduino nano, we needed to test the AEV on the test track located in the Engineering room. Brandon typed out the functions and downloaded it onto the Arduino Nano and then Jacob, Cameron, and Payne all went to the test track to test the AEV out and make sure that it worked. Then after we tested it, we realized that there wasn’t enough power to move the AEV, so we increased our power of the motors to make sure it moved.

We learned that the original code for the AEV to move didn’t have enough power going to the motors to actually get it to move on the test track. So we went into the coding and increased the percent of the power that we need to use. For the testing that we have done, we have never had the battery at full charge. For the next tests, we need to make sure that the battery is at full charge so that we can have an accurate measurement of how much power is needed to move the AEV.
