[image] programming_electronics_academy: It feels like a drop-in replacement for Serial? A replacement for the Serial object as you would use it when writing sketches for other board models, yes. However, note that there is still a Serial object for the UNO Q board. It is just that the Seria…

Hi @programming_electronics_academy I’m exactly in your situation. I guess you are using a Windows 11 PC and Arduino Q via USB. Being in this situation, I was told one week ago to wait for a new release of Arduino App Lab thats should fix this issue, that at least in my mind in far from being a n…

As an aside, I am actually on a Mac, but also using “PC Hosted” mode - i.e., the Arduino Q is connected to my computer via USB. I suppose it is the early days yet for the Q, lots to try and figure out. I have had success with most of the built in App examples.

Hi @apagliari . [image] apagliari: They are trying to sell :money_mouth_face: the “small computer motion” with the dongle with usbc ports… and all related new hardware (usb c cameras, usb c microphones,..) to be bought. I'm not sure I understand what you mean by this. If by "sell", you mean t…

Arduino UNO Q Software updated and now the Serial Monitor is working.

Hi @smolschneider . Did you try the example sketch provided in the documentation?: https://docs.arduino.cc/tutorials/uno-q/user-manual/#from-serial-to-monitor

Yes, but this “serial.print” sends the strings to RX/TX which is the UART. I want to send the text to the monitor resp. the Console displaying in the App Lab of the computer screen. Following to the manual this should be done with: void setup() { // Initialize the Monitor Monitor.begin(); } …

[image] smolschneider: void setup() { // Initialize the Monitor Monitor.begin(); } void loop() { // Transmit the string "Hello UNO Q" followed by a newline character Monitor.println("Hello UNO Q"); delay(1000); } Using Arduino IDE 2.3.7, upload the following sketch and che…

…. I tried all this and it did not work. I want to run som ePython programs (like calculation a fibonacci) number and print out the result to the Console (? Monitor on the App Lab of my Computer ; a MacPro). … the App Lab looks to be a cool environment, but there must be a way to print out a value t…

Arduino UNO Q via IDE - No Serial Monitor Output

Yes, the examples are nice, but a simple “Hello world” does nor print out on the Monitor (Console), this is very confusing?
