Tasks[edit]

Task 1: Getting Started[edit]

Solution Task 1.1: LED Blinking[edit]

 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 1.2 Control external RGB[edit]

 1 # RGB example
 2 
 3 import time
 4 from machine import Pin
 5 
 6 # RGB LED connected to the RP2040
 7 ledG = Pin(25, Pin.OUT)
 8 ledR = Pin(15, Pin.OUT)
 9 ledB = Pin(16, 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)

24     ledB.on()
25     time.sleep_ms(250)

Solution Task 1.3 Read Light-Dependent Resistor (LDR)[edit]

See LDR. 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)


Solution Task 1.4 Combine Light-Dependent Resistor (LDR) with Blinking LED[edit]

 1 from machine import Pin, ADC
 2 import time
 3 
 4 led = Pin(6, Pin.OUT)
 5 analogPin = ADC(Pin(26))
 6 
 7 while (True):
 8   analogVal16 = analogPin.read_u16()
 9   print(analogVal16)
10   rate = analogVal16 / 300 # create a simple mapping
11   led.on()
12   time.sleep_ms(int(rate)) # convert the rate to an integer type
13   led.off()
14   time.sleep_ms(int(rate))

Task 2: Read Data[edit]

  • read data from the accelerometer and the gyro and print them (Arduino IDE) https://docs.arduino.cc/micropython/basics/board-examples/
  • extend your program to write the data from the accelerometers to a file; see the instructions for FileIO.
  • transfer the file to your computer
  • optional: add the photo resistors to your board, read their values, and write them to the file; see the instructions for LDR.

Solution Task 2.1: Read Accelerometer and Gyro[edit]

 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 2.2: Read analog values[edit]

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

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

Task 6: Getting Started with Jupyter Notebook[edit]

  • Connect the board
  • Install the Jupyter Notebook,
  • Read the accelerometer and the gyro and show it in the notebook

Task 6.1: is it moved?[edit]

  • 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 6.2: it was turned upside down?[edit]

  • 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 7: Deploy Machine Learning Models[edit]

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

See EverywhereML for downloading the full example and a dataset to experiment with.

pip3 install -U everywhereml

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. There are other approaches to code generation such as m2cgen https://github.com/BayesWitnesses/m2cgen/tree/master or emlearn https://github.com/emlearn/emlearn

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 8: Connect to WiFi[edit]

This is an optional task.

  • Connect both boards to WIFI using Tutorial Network
  • Use the Arduino Nano RP2040 Connect as output (showing a color)
  • Use the Arduino Nano RP2040 Connect as input (recognize with rules 3 gestures)
