Hardware: Arduino UNO R4 Miniboard Software: Arduino IDE 2.3.6 Microsoft Excel with Data Streamer add-in (Microsoft 365) Problem Description: I'm trying to stream sensor data (digital status from pin 3 and analog value from A0) from my Arduino UNO R4 Miniboard to Excel using the Data Streamer ad…

Also correct. Do you have in the arduino code Serial.print with the appropriate data items? Perhaps show us that.

void setup() { Serial.begin(9600); } void loop() { Serial.println("1,"); delay(1000); } So this is my code. Is this helpful for you?

I would do the most sijple test of Serial.println("1"); BUT have you clicked 'Start Data' in the Excell sheet?

In German, Startdaten must be clicked

How did you 'kill' the Serial monitor?

[image] When I open it it appears on the left of the output tab. I close it then with the "x" on the tab...

[image] huggi0619: I tried this one: That’s only a snippet of code printing to Serial monitor. How is the controller connected to the Pc? Using USB it will work unless You have a damaged or defect controller.
