What would you recommend I do now?

There are two usb serial ports on theUNO R4. One is used for normal serial communications and the other is used for program upload. Some times the UNO R4 does not manage the switching between the ports correctly. The issue is discussed here
https://github.com/arduino/ArduinoCore-renesas/issues/73

The work around (which may actually fix the situation for further uploads) is to manually put the board into programming mode, and select the port in the ide for the upload.

Workaround

Unplug the USB cable of the UNO R4 WiFi board from your computer.

Connect the UNO R4 WiFi board to your computer with the USB cable.

Press and release the button marked "RESET" on your UNO R4 WiFi board quickly twice.
You should now see the "L" LED pulsing.

Select the port of the UNO R4 WiFi board from Arduino IDE's Tools > Port menu.
The double reset you did in step (3) can cause the port number of the board to change, so don't assume you already have the correct port selected.

Upload the sketch to the board as usual.

You may want to confirm that when you double press the reset button you can indeed see the port change.

I have other boards which sometimes have trouble switching the ports, and manually putting the board into programing mode so you see the L led pulsing is used on them as well.

Ok. Your steps worked! Thank you so much! I believe my Arduino did not work because I had no USB connection to the computer . Anyhow, I continued onto step 10 of the experiment and downloaded grove_control_LED.ino, which consists of the following code:

#include <SoftwareSerial.h>
 
#define SOFTSERIAL_RX_PIN  2
#define SOFTSERIAL_TX_PIN  3
 
SoftwareSerial softSerial(SOFTSERIAL_RX_PIN,SOFTSERIAL_TX_PIN);

int led = 13;
 
const char *voiceBuffer[] =
{
    "Turn on the light",
    "Turn off the light",
    "Play music",
    "Pause",
    "Next",
    "Previous",
    "Up",
    "Down",
    "Turn on the TV",
    "Turn off the TV",
    "Increase temperature",
    "Decrease temperature",
    "What's the time",
    "Open the door",
    "Close the door",
    "Left",
    "Right",
    "Stop",
    "Start",
    "Mode 1",
    "Mode 2",
    "Go",
};
 
void setup()
{
    Serial.begin(9600);
    softSerial.begin(9600);
    softSerial.listen();
    pinMode(led,OUTPUT);
    digitalWrite(led,LOW);
}
 
void loop()
{
    char cmd;
 
    if(softSerial.available())
    {
        cmd = softSerial.read();
        Serial.println(voiceBuffer[cmd - 1]);

        if((voiceBuffer[cmd - 1]) == "Turn on the light"){
          digitalWrite(led,HIGH);
        }
        else if((voiceBuffer[cmd - 1]) == "Turn off the light"){
          digitalWrite(led,LOW);
        }
    }
}

However, when I uploaded this set of code, the following output and error messages resulted:

What would the recommended fix for this issue be?

NOTE: I am still using Arduino IDE 2.3.4 per @UKHeliBob's instructions in post 20.

Use Serial1 instead of Software Serial. You've been down this road before. See Post #4.

gfvalvo · February 5, 2025, 1:43am

Why use SoftwareSerial? Doesn't UNO R4 have an available hardware UART?

tgg1 · February 5, 2025, 1:50am

I changed all mentions of "SoftSerial" and "Serial" to "SoftSerial1" and "Serial1," but it still won't work.

gfvalvo · February 5, 2025, 1:59am

You need to be more specific than that.

Did it compile after switching to Serial1? Did you properly connect the Grove Speech Recognizer to the correct pins to use Serial1 instead of SoftwareSerial?

tgg1 · February 5, 2025, 2:00am

This is the code after I altered it:

#include <SoftwareSerial.h>
 
#define SOFTSERIAL_RX_PIN  2
#define SOFTSERIAL_TX_PIN  3
 
SoftwareSerial softSerial(SOFTSERIAL_RX_PIN,SOFTSERIAL_TX_PIN);

int led = 13;
 
const char *voiceBuffer[] =
{
    "Turn on the light",
    "Turn off the light",
    "Play music",
    "Pause",
    "Next",
    "Previous",
    "Up",
    "Down",
    "Turn on the TV",
    "Turn off the TV",
    "Increase temperature",
    "Decrease temperature",
    "What's the time",
    "Open the door",
    "Close the door",
    "Left",
    "Right",
    "Stop",
    "Start",
    "Mode 1",
    "Mode 2",
    "Go",
};
 
void setup()
{
    Serial1.begin(9600);
    softSerial1.begin(9600);
    softSerial1.listen();
    pinMode(led,OUTPUT);
    digitalWrite(led,LOW);
}
 
void loop()
{
    char cmd;
 
    if(softSerial1.available())
    {
        cmd = softSerial1.read();
        Serial1.println(voiceBuffer[cmd - 1]);

        if((voiceBuffer[cmd - 1]) == "Turn on the light"){
          digitalWrite(led,HIGH);
        }
        else if((voiceBuffer[cmd - 1]) == "Turn off the light"){
          digitalWrite(led,LOW);
        }
    }
}

This is the error message I got:

Why did you keep that line if you're using Serial1 now?

Same question with this:

tgg1 · February 5, 2025, 2:10am

So, I removed those two lines (seen in post 29) and changed all mentions of "SoftwareSerial" and "SoftSerial" to Serial1," leaving me with this code:


 
#define SOFTSERIAL_RX_PIN  2
#define SOFTSERIAL_TX_PIN  3
 


int led = 13;
 
const char *voiceBuffer[] =
{
    "Turn on the light",
    "Turn off the light",
    "Play music",
    "Pause",
    "Next",
    "Previous",
    "Up",
    "Down",
    "Turn on the TV",
    "Turn off the TV",
    "Increase temperature",
    "Decrease temperature",
    "What's the time",
    "Open the door",
    "Close the door",
    "Left",
    "Right",
    "Stop",
    "Start",
    "Mode 1",
    "Mode 2",
    "Go",
};
 
void setup()
{
    Serial1.begin(9600);
    Serial1.begin(9600);
    Serial1.listen();
    pinMode(led,OUTPUT);
    digitalWrite(led,LOW);
}
 
void loop()
{
    char cmd;
 
    if(softSerial1.available())
    {
        cmd = Serial1.read();
        Serial1.println(voiceBuffer[cmd - 1]);

        if((voiceBuffer[cmd - 1]) == "Turn on the light"){
          digitalWrite(led,HIGH);
        }
        else if((voiceBuffer[cmd - 1]) == "Turn off the light"){
          digitalWrite(led,LOW);
        }
    }
}

I also received this output and error message:

Why do you have that written twice?

Serial1 doesn't have or need the listen() function.

Ooops

tgg1 · February 5, 2025, 2:21am

I fixed it! Thank you so much! Maybe it's because I stay up for 16 hours straight every day.

tgg1 · February 5, 2025, 2:25am

Thanks so much!!! It worked and I'm able to control the lamp, now! I really appreciate all of your guys help, including @cattledog, @UKHeliBob, @StefanL38, and @gfvalvo. Now I know how to control an Arduino!

tgg1 · February 11, 2025, 10:19pm

Hello everyone! I'm back again to ask another question. I will be presenting this at a science fair in a couple weeks. To demonstrate my project to its fullest (i.e.: have it turn a light on and off), do I have to connect my Arduino, Grove Speech Recognizer, and IOT Relay to WiFi and/or to a computer, or would my equipment work on its own? Thank you and have a great afternoon!

StefanL38 · February 11, 2025, 10:43pm

No you don't really "know" how to control an arduino. This would require weeks of learning 5 to 8 hours per day to really know an arduino.

It seems you started from zero knowledge one week ago.
did some copy and paste and posted error-messages without having a glimpse what the error-messages mean.

You will have to be much more specific.

describing with much more precission and much more details what your actual code does
describing with much more precission and much more details what "my equipement" means? Listing up each and every part that you are using
describing how this "IOT-relay" is now involved
describing what kind of IOT you are using is it
RemoteXY?
Blynk?
Arduino IoT-cloud?
something else?

You are working on an informatic project and in an informatic project the most needed thing is detailed information

I recommend that 4 weeks before you have to present your projects
make a simulated presenetation.
Go to a friend or any different place take with you what equipment you think you need and try to run your lamp on this different place.

I promise you:
you will discover many many things that go wrong in the first, in the second,an in the third attempt.

From loose wires
to no Wifi-Connection
to B
to C
to X
to y
to Z

There is always a learning curve in everything.

tgg1 · February 12, 2025, 3:09am

Hello everyone! I seem to have encountered another issue with my Arduino/equipment. A couple days ago, I accidentally dropped my entire project setup, and I was able to correctly identify all of the wiring connections before I dropped my equipment. However, upon trying to get the light to turn on, I found that the light would not turn on.

Tonight, after messing around with the code and the wiring connections, I ended up with this new code:

#include <SoftwareSerial.h>

#define SOFTSERIAL_RX_PIN  2
#define SOFTSERIAL_TX_PIN  3

SoftwareSerial softSerial(SOFTSERIAL_RX_PIN,SOFTSERIAL_TX_PIN);

const char *voiceBuffer[] =
{
    "Turn on the light",
    "Turn off the light",
    "Play music",
    "Pause",
    "Next",
    "Previous",
    "Up",
    "Down",
    "Turn on the TV",
    "Turn off the TV",
    "Increase temperature",
    "Decrease temperature",
    "What's the time",
    "Open the door",
    "Close the door",
    "Left",
    "Right",
    "Stop",
    "Start",
    "Mode 1",
    "Mode 2",
    "Go",
};

void setup()
{
   
    softSerial.begin(9600);
 
}

void loop()
{
    char cmd;

    if(softSerial.available())
    {
        cmd = softSerial.read();
        Serial.println(voiceBuffer[cmd - 1]);
    }
}

and this output:

Could someone please verify whether or not this is correct to resolving my issue? Thanks!

If you dropped it, why write new code, that would not have been damaged at all.

Did you draw a circuit diagram, how did you check your wiring.

Do you have a DMM? Digital MultiMeter?

You need to check all your wiring, new code will not necessarily fix the problem.

Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

You still don't get it.
As long as you don't provide sufficient information everything is just guessing.
Sufficient information means what user @TomGeorge wrote.
Additionally the compile log you posted just says the compiling was successfully.
That is insufficient.

what does

mean?

what does

mean?

You have to be much more specific.

What does

mean ?

What did you change in the code?
what did you change in the wiring?

I guess you can't tell because you have not documented it.
Hm well just one of the things to learn. Document your project

If you compare your two codes what differences to you detect?

What do you think makes a good presentation?

saying the words
"this is my arduino, this is my voice-recognition-module
this is the code
and now I will demonstrate you switching on/off the lamp"
???
You will be asked amany questions about the details.
And you should be able to answer them

what kind of interface is used between the arduino and the module?
what do you have to change in the code to make it react to different commands?
