    • Standard UART on the Mega runs at 115 200 bps. Transferring a 2 KB Base64 string (~2.7 KB raw) therefore consumes roughly 200 ms of raw transmission time. Adding the framing overhead and checksum, the end‑to‑end latency measured from hotkey press to LED confirmation averaged 350 ms, acceptable for most documentation workflows but noticeable in high‑speed gaming contexts.

    Mitigation: Participants experimented with binary transmission (avoiding Base64) and higher baud rates (up to 250 000 bps). While binary cut latency by ~30 %, reliability on cheap USB‑to‑UART adapters suffered, prompting a return to Base64 for its robust character framing. screenpresso133withserial mega 2021

    Traditional screen‑capture workflows are unidirectional: a user clicks a hotkey, an image is saved, and the workflow proceeds on the computer. By inserting a serial endpoint into this loop, the designers aimed to: Editing : Use built-in editing tools to annotate,
