So, rather than send those 2 small values as TSV, w/ lotsa extra separator characters, we can simply send 2 bytes only using Serial.write(): [https://www.Arduino.cc/reference/en/language/functions/communication/serial/write/](https://www.Arduino.cc/reference/en/language/functions/communication/serial/write/) We just need to create a char array of length = 2: signed char xy[2]; #define BAUDS 115200 #define DELAY 10 #define…
