This course is designed as a week-long tutorial to engage with ubiquitous devices in the domain of smart environments and how to use machine learning to build smart devices. Here, we use an Arduino Nano RP2040 Connect (https://store.arduino.cc/products/arduino-nano-rp2040-connect).

Tasks

Task 0: connect an Arduino Nano ESP32 board

Solution Task 0.1: LED Blinking

 1 # Blinky example
 2 
 3 import time
 4 from machine import Pin
 5 
 6 # This is the only LED pin available on the Nano RP2040,
 7 # other than the RGB LED connected to Nano WiFi module.
 8 led = Pin(6, Pin.OUT)
 9 
10 while (True):
11    led.on()
12    time.sleep_ms(250)
13    led.off()
14    time.sleep_ms(200)

Solution Task 0.2 Control external RGB

 1 # RGB example
 2 
 3 import time
 4 from machine import Pin
 5 
 6 # RGB LED connected to Nano WiFi module.
 7 ledG = Pin(2, Pin.OUT)
 8 ledR = Pin(3, Pin.OUT)
 9 ledB = Pin(4, Pin.OUT)
10 print("start")
11 
12 while (True):
13     print("*")
14     ledG.on()
15     ledR.off()
16     ledB.off()
17     time.sleep_ms(250)
18     ledG.off()
19     ledR.on()
20     ledB.off()
21     time.sleep_ms(250)
22     ledG.off()
23     ledR.off()
24     ledB.on()
25     time.sleep_ms(250)

Task 1: read Acceleration from Arduino Nano ESP32 board

Solution Task 1.1: Read Accelerometer and Gyro

 1 import time
 2 from lsm6dsox import LSM6DSOX
 3 
 4 from machine import Pin, I2C
 5 lsm = LSM6DSOX(I2C(0, scl=Pin(13), sda=Pin(12)))
 6 
 7 while (True):
 8     accel_data = lsm.accel()
 9     print('Accelerometer: x:{:>8.3f} y:{:>8.3f} z:{:>8.3f}'.format(*accel_data))
10     gyro_data = lsm.gyro()
11     print('Gyroscope:     x:{:>8.3f} y:{:>8.3f} z:{:>8.3f}'.format(*gyro_data))
12     print("")
13     time.sleep_ms(100)


Solution Task 1.2: Read analog values - Code Example Arduino Nano Connect RP2040

A0 is the analog input with 16 bit resolution. It reads the analog value every second and print it to the console- 

 1 #Example usage for Arduino Nano
 2 from machine import Pin, ADC
 3 from time import sleep
 4 
 5 analogPin = ADC(Pin(26))
 6 
 7 while True:
 8   analogVal16 = analogPin.read_u16()
 9   print(analogVal16)
10   sleep(1)

Task 2: Jupyter Notebook


Task 2.1: is it moved?

  • read acceleration and gyro
  • calculate the differences between values
  • show an ouput when it is move
  • create a file on the device that logs, when it is moved

Task 2.2: it was turned upside down?

  • read acceleration and gyro
  • make a rule based "AI" that records
    • it was put upside down
    • it was turned 360
    • it was moved "quickly"

Task 3: ML on Arduino Nano Connect RP2040

We will use https://github.com/eloquentarduino/everywhereml to detect the same gestures as in Task 2.2. For this, install everywhereml: 

pip3 install -U everywhere

Using everywhereml we can train a model on a more powerful machine for deployment on a microcontroller. See https://eloquentarduino.com/posts/micropython-machine-learning for example for such a training process. Assuming that our ML model is trained and stored in variable clf then we can save the model to a file using 

clf.to_micropython_file("MyModel.py")

The MyModel.py file can then be saved and called directly on the microcontroller. To run the model on the microcontroller, assume your data is stored in x and you trained a RandomForestClassifier. Then you can predict via the following code snippet 

import MyModel
clf = MyModel.RandomForestClassifier()
clf.predict(x)

Task 4: connect both boards to WIFI

  • connect both boards to WIFI using Tutorial_Network
  • use the Arduino Nano ESP32 as output (showing a color)
  • use the Arduino Nano Connect RP2040 as input (recognize with rules 3 gestures)
