Experiencing lots of lag

Using two different readStringUntil "characters"

Well, I don’t have any Arduino hardware and neither even seen 1 in front of me yet! So I can only do blind coding in the dark for you. Theoretically, an Arduino C code like this 1: void setup() { Serial.begin(115200); } void loop() { const int x = map(analogRead(A1), 0, 1023, -10, 10); const int y = map(analogRead(A0), 0, 1023, -10, 10); Serial.print(x); // "-5" Serial.write('\t'); // '\t' Serial.println(y); // "10" + "\r\n" delay…
