After trying out the previous tutorial, we found that we could get the first one (the one with the etch e sketch frame) to work, but still found some faults in that the top of the screen couldn’t be used, and if you went to near the top, then it would erase what was on the screen.
With the second tutorial, the problem we found was that the code in arduino was not accurate enough for processing to find the arudino board port. Therefore it could not be used well

Therefore we have tried to develop this further b y creating basic processing code that could run the same system, but hopefully with less issues.
