Tips
- Use Google Chrome or Microsoft Edge — Web Serial is not supported in Firefox or Safari.
- For the Serial Plotter, print numbers separated by commas or spaces from your Arduino (e.g.
Serial.print(val1); Serial.print(","); Serial.println(val2);). - Up to 6 data channels can be plotted simultaneously.
- The monitor keeps the last 500 lines; the plotter keeps the last 200 samples.
