Hey Kevin,
Looks like we’ve got a few errors here. Can you please send through your code from loop down too?
I’m fairly sure it’s just that there’s no implicit conversion between the two data types that are being used here. You should just need to identify which line needs to be which datatype and then switch it in the code so that it compiles correctly.
Hi Bryce,
I was just trying to see if the example code in Arduino would Verify, which it didn’t. The code I am trying to incorporate these two devices into is quite extensive, but all worked with no errors. I did have an Adafruit Distance Sensor originally working, but changed to the piico. I am also still not understanding how to code in the I2c for the VEML6030 and VL53L1X, I can’t get me head around the example: [[I2C Bus and the Arduino - Tutorial]]((https://core-electronics.com.au/tutorials/i2c-with-arduino.html)

This is an electronic eye for my newly blind dog.
The original code:
IMU algorithm detects movement of the Nano33BLE and then reads distance from objects which then turns on a buzzer, vibrator motor to indicate to the dog an object is in his way. This is done within the ‘case’ code.
The new code changes distance sensor from adafruit to piico and adds in a piico light sensor connected toI2C as well as an Adafruit FX board connected o UART.
IMU algorithm detects movement of the Nano33BLE and then reads distance from objects which then turns on a buzzer, vibrator motor and vocal commands to indicate to the dog an object is in his way. This is done within the ‘case’ code. Light sensor turns an LED on and off when dog is moving in the dark so we can see him if he goes outside.
That is as simple as I can explain it
Any suggestions to why the example coding in Arduino IDE for the VEML6030 piico light sensor and the VL53L1X piico distance sensor as they won’t compile?
I was told to use these:
Can you post the compile error messages and what you did to install the libraries ??
There are a number of reasons why something might not compile.
I found both libraries in the Arduino IDE, installed them and compiled the examples ok.
Note: I did not use GitHub and I don’t have a VEML6030 or VL53L1X to test it further.
Getting the right library and getting it to work can be quite frustrating with the Arduino IDE. I have used the IDE extensively for many different devices, it could be something simple that is causing it not to work or it could be quite complex.
If I can see the compile messages I might be able to help.
Cheers

Hi Kevin,
I would have a watch of chapter 5’s guide here: https://core-electronics.com.au/tutorials/arduino/arduino-workshop-for-beginners.html
Sam runs through getting an I2C sensor hooked up to the Arduino. Those two libraries are just from a couple well known Maker companies, there are plenty others and will have different function calls and even differing amounts of functionality worked into them.
Let me know if you need anything else.
Would I of been able to use my original code using adafruit VL53L0X with the piico VL53L1X?
Loaded your code and compiled it ok, eventually. Found 2 issues as listed in the error messages.
error one: class and I2C address assignment
#define VL53L1X_sensor 0x29
VL53L1X sensor (VL53L1X_sensor);
change to
#define VL53L1X_sensor 0x29
VL53L1X sensor;
add the I2C address assignment to setup
void setup() {
sensor.setAddress(VL53L1X_sensor);
{
Serial.begin(9600);
while (!Serial);
Serial.println("Started");
error two: syntax
if (luxVal >= 10);
{digitalWrite(D2, 255);
delay (1000);}
else {digitalWrite(D2, 0);
}
change to
if (luxVal >= 10)
{digitalWrite(D2, 255);
delay (1000);}
else {digitalWrite(D2, 0);
}
Note: removal of ; at end of if statement
Regards
Jim
Thanks Jim
Its usually something small like this and you can’t see for looking. Always good to have a second set of eyes go over it. I will give that a go and post my results.
HI Jim
I ran the sketch with the adjustments you suggested. All those errors are gone.
However there is a new one for the light sensor:

Hi Kevin,
The line int time = 100; redefines a variable that is used by some of the include libraries or Arduino built in libraries. There are quite a few of these variables. This has caught me out a few times too.
Simple fix, change time to time_01 or something that makes sense to you. Also you will need to change everywhere in your code where time is referenced to time_01.
Hopefully that should fix it.
Cheers
Jim
That is awesome, I will do that. Thanks Jim.
Is there a way to open the arduino library files to see the code?
That seems to of worked but now it is giving an error for the Arduino Nano 33 BLE and the piico VL53L1X sensor module. Can I use coding for the VL53L0X sensor, as I used that in my original code and it works I only changed when I was referred to use the piico range to bring costs down and to use I2C to simplify wiring.

Error compiling for board Arduino Nano 33 BLE.
These errors are in the libraries, not a place I would want to alter.
Usually it means the library has not been debugged enough or is not written correctly or something else.
When this has happened for me I start looking for a better library or one that works.
I would do what you say, go back to a stage that worked. VL53L0X sensor code.
Regards
Jim
EDIT: Sometimes the libraries may not be valid as zip files or may be out of date.
Suggest using the Arduino Library manager to install libraries, these are kept up to date and usually don’t make it to the list unless they are fully debugged.
I think the VL53L1X library you have used is the Pololu Git Hub link, try the Adafruit one, all Adafruit libraries I have used work nicely. Pololu make excellent stuff, most of the time their libraries are good, I have experienced a couple that were not.
Thanks again Jim your a legend. These small things are sometimes the worst to find without a good understanding/ I am coming from a logic programming background with industrial PLC’s. No libraries just code that is a written logical story. Arduino is fantastic its just going to take me a few more mistakes to learn it better. I am glad I found Core this is a great shop a resource you guys are awesome. Lets see how I go now.
When combining sketches some have different serial bus speeds called on at serial.begin is only one needed for wire or for each module?
