It also has a nice little box made for it, hence the name text/html 2024-08-21T01:38:56+00:00 Anonymous (anonymous@undisclosed.example.com) https://pvela.gatech.edu/classes/doku.php?id=ece4560:controlbox:issues&rev=1724204336&do=diff Resolving Issues with the Arduino Control Box The Arduino microcontroller used has limited memory, while the student who programmed it used a lot of bloated publicly available libraries. That combination means that there is very little memory for runtime variables. Most things are manageable except for the communication part. When there is too much communication, then slow processing and filling buffer lead to memory overflow. I don't know what happens, but either programming memory is over…
