Install the Modulino MicroPython library (see Getting Started with Modulinos for detailed instructions)
click on this link - you get - Oops! There’s nothing here
please can Arduino provide instruction on how to install modulino for python
as required for program
from modulino import ModulinoVibro
fromtimeimport sleep
vibro = ModulinoVibro()
while True:
# Vibrate for 1 second
vibro.on(duration=1000)
sleep(1)
# Turn off
vibro.off()
sleep(1)
@michaelbusfield is this the link you need?
Thanks for bringing this to our attention! I have submitted a formal report to the team responsible for the documentation on your behalf. I apologize for any inconvenience caused by the broken link.
The link is intended to target this page:
https://docs.arduino.cc/tutorials/modulino-thermo/how-general/
It might seem like the information in that tutorial won't be applicable to the Modulino Vibro, since it is located under the section of the documentation website dedicated to the Modulino Thermo. However, this tutorial is actually written to be generally applicable to all the Modulino Node products. The documentation team just arbitrarily placed it in the Modulino Thermo section, since the structure of the documentation website doesn't accommodate storing tutorials under a section that is general to a family of products.

As I know, Arduino NANOESP32 comes with a pre-installed Python interpreter which you have to enable. Check internet for the procedures.
Arduino has provided an IDE to create Python Script and then upload it into NANOESP32.
I played a bit few yeras ago; now I have forgotten almost everything. Currently, I am learning Pyhthon again using App Lab and Arduino UNO Q.
Thanks,
python programs are running perfetly on this nanoesp32 - it’s only modulino programs that are not working
Using UNO R4 or UNO Q check that your Modulino Module is workng.
already done - modulino vibro and thermo working fine with nanomatter running c/c++
Now, next step is to chcek your Modulino Module using UNO Q (if you have) which supports both Python Script and Arduino Sketch.

1. Have you connected the Modulino Module with the UNO Q board usin the Qwiic connector? Modulino Module is an I2C bus driven device handled by the MCU of the UNO Q. After making the connection, please take a photo with your mobile camera and post it here.
2. Now perform the following experiment to understnaf how MCU sends signal to MPU using Router Bridge for onward printin on the Console>>Python.
Step - 6 of this tread.
Repeated below:
6. Passing ADC data from MCU to MPU using Router bridge. Connect the Pot with MCU as per Fig-1.
Python Script for MPU (tested)
from arduino.app_utils import *
import time
last_print = 0
interval = 0.1 # seconds between loop checks
# A container to hold the latest ADC value
latest_adc = None
# This function will be called automatically when MCU sends notify
def on_adc(value):
global latest_adc
latest_adc = value
# Subscribe to MCU notifications
Bridge.provide("adc_data", on_adc)
def loop():
global last_print, latest_adc
current_time = time.time()
# Check every 100ms if there is new data
if latest_adc is not None and current_time - last_print >= 1:
voltage = latest_adc * (3.3 / 1023.0)
print(f"ADC: {latest_adc}, Voltage: {voltage:.3f} V") #shows on: Python console
last_print = current_time
App.run(user_loop=loop)
Arduino Sketch for MCU (tested)
#include "Arduino_RouterBridge.h"
void setup()
{
analogReadResolution(10);
Monitor.begin();
Bridge.begin();
}
void loop()
{
int adc = analogRead(A0);
Bridge.notify("adc_data", adc);
Monitor.println("Seding data to MPU."); //shows on: Serial Monitor of IDE and Console
delay(1000);
}
3. Now, develop app (application = script + sketch) using App Lab to show the readings of he Modulino onto Console>>Serial Monitor at 1-sec interval.
Thaks for this - program did run but then appeared to crash - eror message -Using CPython 3.13.9 interpreter at: /usr/local/bin/python

Channge the above line to the following and try again:
#include <Arduino_RouterBridge.h>
If the above does not work, do the following:
Now, you have do the trouble beginning the execution of small basic script.
1. Use App Lab to execute the following app.
Script: to show the message Forum on Console>>Python at every 1-sec inerval.
Sketch: to show the A0-voltage (Fig-1, post #14) on Console>>Serial Monitor at 1-sec interval.
2. Modify both the script and the sketch from Step-1 so that the MCU uses Bridge.notify() to send A0-voltage, and the script uses Bridge.provide() to collect the data at 1-second intervals.
simple C/C++ program on Arduino UNO Q working fine
#include <Arduino_RouterBridge.h>
#include <Modulino.h>
// Create object instance
ModulinoThermo thermo;
// Global Variables
float celsius = 0;
float humidity = 0;
void setup(){
// Initialization of the serial port, modulino object and thermo one
Modulino.begin();
thermo.begin();
Monitor.begin();
}
void loop(){
celsius = thermo.getTemperature();
humidity = thermo.getHumidity();
Monitor.print("Temperature (C) is: ");
Monitor.println(celsius);
Monitor.print("Humidity (rH) is: ");
Monitor.println(humidity);
delay(1000);
}
Still do not undersand why the modulino python programs are not working on devices such as NANOESP32

Repeated duplicate posting could result in a temporary or permanent ban from the forum.
Could you take a few moments to Learn How To Use The Forum
It will help you get the best out of the forum in the future.
Thank you.
I don't know python sorry..
From post #4 I see you appear to be missing device_manager.py, this was added to the git under branch tag motor..
I do not see it listed in the package.json and I'm thinking this is why you're missing it??
Manually download it and place it in the /lib/modulino/ folder might get you working..
good luck.. ~q
Please Arduino update the Micropython package installer for Modulino so that it adds all files needed.
I can find a device_manager.py file online but its not clear how to get this into the .mpy format required
The version of the Modulino package loaded by the Arduino Micropython package installer is clearly out of date.
the instructions and developer instructions provided on
do not work
Please can Arduino update all so that NANOESP32 can be used with Modulinion in Python
Thanks to Sebastian Romero for updating the Arduino Modulino package. Python Modulino programs are now working on NANOESP32.
