I'm following the directions found here >https://learn.sparkfun.com/tutorials/experiment-guide-for-redbot-with-shadow-chassis/experiment-1-software-install-and-basic-test and whenever I try and upload any code to the arduino I receive the errors below. The COM port is correct and the board is set to Arduino Uno/ Genuino Uno. Any help would be much appreciated.
