Only need to declare serial.begin once, and whatever you set needs to be compatible with all devices.
It sets the speed of the TX/RX lines for the UART on the Arduino. (pins D0 & D1)
Most of the time I only use serial as a program debug; printing stuff to the Arduino Console window.
Once I did use it to send commands between a UNO and a Pi Zero, worked pretty good.

Thanks thought only once was needed.
Thanks guys, got it all working, light and distance sensor on I2C all working. Just need to get the Adafruit Sound FX module working.
I found this helpful:
Hi Kevin,
Thanks for posting resources you find helpful, you may save someone in the future a lot of stress with a similar problem.
Andreas Spiess does have some excellent tutorials so itâs worth checking out his other videos.
Good luck with the Sound FX module, let us know how you go with it.
I have been working on the adafruit sound fx, I just wanted ask about the SoftwareSerial.h library it asks for. It say it is a arduino included library, which I canât find, nor can I find where to download it from anywhere. It isnât included in the adafruit sound fx board files either.
Can you suggest where to find it, I canât go further with the board otherwise. I thought Iâd ask you first before going to Adafruit direct as there will be a few days delay in replies.
Thanks Kev
Thanks, that is the missing file.
This is the Adafruit Sound FX board example file.

> Error compiling for board Arduino Nano 33 BLE.
Is it possible that this code wonât work on a Nano33BLE format. I found this earlier:
SoftwareSerial.h Library not found - Using Arduino / Installation & Troubleshooting - Arduino Forum
As you discovered, there is no SoftwareSerial library for the SAMD architecture of the Nano 33 IoT. However, there is no need for one. The Nano 33 IoT has an unused hardware serial port named Serial1 on pins 0 and 1, so just use that. It's also possible to get more if you need it, but you most likely don't so we won't worry about that.
Note that the Nano 33 IoT is different from the classic Nano because the serial port on pins 0 and 1 (Serial) on the classic Nano is also used for uploading sketches and other communication with the computer (e.g., Serial Monitor), so it's not really convenient to use Serial for other purposes on the classic Nano. This is why you will often see people using SoftwareSerial library with the Nano, Uno, Pro Mini, etc. But the Nano 33 IoT is different because the Serial1 serial port on pins 0 and 1 is not used for anything, so you are free to use those pins for your own purposes.
If so, I take it if I do as this guy was instructed?
Two more questions. I wanât the Sound FX board to be triggered to play âPower is ONâ when the unit is turned on. What can I use as the trigger?
Is there a need to calibrate the Nano33BLE IMU(I use to measure movement and angles, Piico Distance sensor, Piico Light Sensor? If so, when(eg, every time on start up, once when first using? Is this the same with the other modules? If so how do I do it, as it will need to be easy to do for someone that has no idea on this sort of stuff.
Youâre most welcome, Kevin. Would not hurt to try the suggestions in that thread. Nobody there reported any holy smoke coming out of the boards.
Regarding the calibration, Adafruit has a page.
Regarding coding, Jim will be a better help. My expertise with codes stop at filling in the postal codes on mail.
cheers G
I have been trying to get the Adafruit SoundFX board working via TX/RX on Nano33BLE which I have found out is Serial1. here isnât much info on this as it is different to other Arduino modules. I am having trouble with the code, it says I have not declared in the scope:

Arduino forum explanation, but no example. OK for someone experienced but not for a nubie
Can someone simply explain how to declare and setup Serial1 to write(TX) to the adafruitSFX(RX) and read SFX(RX) to (BLE)TX?
This is the example given by Adafruit:

> Vol + and - (only when not playing audio)

> Current play time, and bytes remaining & total bytes (when playing audio)
>
> Connect UG to ground to have the sound board boot into UART mode

Means the compiler does not know what âSerial1â is and therefore does not know what to do with it.
The Arduino has a built-in hardware USART to send and receive serial data. This is also used to load programs and for debugging making it hard to use a serial port for a project. The âSoftware Serialâ library was developed to over come this problem. It sends serial data via two PWM pins on the Arduino. This is what the Adafruit example is doing.
âSerial1â is just a way of differentiating between the built-in hardware serial port and one that use a software approach. âSerialâ is defined in the core compiler libraries. âSerial1â is also used in relation to the Atmega 2560 board, the processor on that board has 4 hardware USARTs. Would steer away from using âSerial1â.
The processor on the Nano33BLE (SAM D21/DA1) is quite powerful and configurable. But pretty sure the Nano interface is just like a normal Arduino. Most Arduino libraries should work ok.
Suggest you use the Adafruit example to get the connection between the Nano and Sound FX board working. The code defines D4 Reset, D5 TX, D6 RX. Actual pins on the Nano are 22, 23, 24 respectively.
So connect âŚ
Nano pin 22 to RST on Sound board.
Nano pin 23 (TX) to TX on Sound board.
Nano pin 22 (RX) to RX on Sound board.
The Adafruit web page for the Sound board defines TX as an output and RX as an input; normally you would connect TX to RX. (output to input).
But the Adafruit example swaps the TX & RX definitions in:
SoftwareSerial ss = SoftwareSerial(SFX_TX, SFX_RX);
The built-in Software Serial example defines it as:
SoftwareSerial mySerial(10, 11); // RX, TX
Maybe Adafruit thought it would help to just connect TX to TX but for people like me having worked in serial communications all my life, we would naturally connect TX to RX and wonder why it does not work. This kind of confusion has happened many times in the past.
Once you get the Adafruit example to work you can incorporate it into your other code.
Apologies for not keeping abreast of your development, I have been busy on Raspberry Pi stuff.
Regards
Jim
To do this, in void setup() make the last step sending a command to the Sound board to play the track where you have recorded âPower is ONâ.
sfx.playTrack("name");
name would be whatever the file is called.
You may need to add a delay while the track is played and then pause the Sound board.
delay(2000); // wait 2 seconds.
sfx.pause();
Regards
Jim
I have been trying for the last week. SoftwareSerial.h doesnât work with Nano33BLE board which I found others have found as the TX(1)/RX(3) ports on the board are hardware based as Serial1.
Also get the following error with the Adafruit code for the SFX

> Error compiling for board Arduino Nano 33 BLE.
> ```Being hardware Serial, I found allot of people saying to just create a simple sketch like the following(it took me a bit to get it to compile as I wasnât declaring things correctly(like Serial1 and incomingByte). I got the following to compile. I havenât run it with my main code yet so crossing fingers:
#include <Arduino_LSM9DS1.h>
char incomingByte = 0;
void setup() {
Serial1.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
if (Serial1.available() > 0)
{
incomingByte = Serial1.read(); //read the incoming byte
Serial1.print("Received: ");
Serial1.println(incomingByte, DEC); //send the byte to the terminal in decimal format
Serial1.write("SFX Board recieved loud and clear");
}
}
Is this working in the right direction or am going down the wrong path?
@Kevin79611 Thought just occurred to me.
The Nano33BLE is programmed via the USB interface. And further reading of the Arduino help page states the TX1 RX0 pins are defined as Serial1. The instructions on the page detail installing a Board driver which would then allow use of Serial1. Arduino Mbed OS Nano Boards.
YES !!! It is the right direction as long as you have loaded the Board driver as per the web page.
.
Pretty much my last 2 posts are useless, deleted them. I am just working through the problem and trying to understand the board without having one in front of me.
Use Serial1 in your code to send commands to the Sound board using the Adafruit Library.
Connect TX1 (output) on the Nano33BLE to RX (input)on the Sound board.
Connect RX0 (input) on the Nano33BLE to TX (output) on the Sound board.
Adafruit example changed to use Serial1, compiles ok. Code below.
Sorry, some of my help has been useless, the path I have taken is what would have happened anyway if it was my project.
Hope this helps.

Any help is help. I will give it a try tomorrow, just had a nice feed out for the first time in a year thanks to covid. Iâll post how I go and once I get it right I will try and compile a simple âHow tooâ as I like the Nano33BLE and would like to try the Sense, there is just lacking tutorials at the moment.
Cheers

In the Adafruit tutorial on Serial triggering:
Serial Audio Control | Adafruit Audio FX Sound Board | Adafruit Learning System
It says you can call for a track to play by name using the following format:
(PT09 WAV\n);
But I get the following error, can anyone explain why:
stray \ in program
â\nâ is like pressing the âenterâ key, newline etc.
Possible you donât need it anymore. Or it might be sent automatically.
Try without the â\nâ.
Adafruitâs tutorial is pretty old now.

Jim
