Tasks

Project 0: connect a Arduino Nano ESP32 board

solution Project 0: LED Blinking

# Blinky example

import time
from machine import Pin

# This is the only LED pin available on the Nano RP2040,
# other than the RGB LED connected to Nano WiFi module.
led = Pin(6, Pin.OUT)

while (True):
   led.on()
   time.sleep_ms(250)
   led.off()
   time.sleep_ms(200)

solution Project 0: Control external RGB

# RGB example

import time
from machine import Pin

# RGB LED connected to Nano WiFi module.
ledG = Pin(2, Pin.OUT)
ledR = Pin(3, Pin.OUT)
ledB = Pin(4, Pin.OUT)
print("start")

while (True):
    print("*")
    ledG.on()
    ledR.off()
    ledB.off()
    time.sleep_ms(250)
    ledG.off()
    ledR.on()
    ledB.off()
    time.sleep_ms(250)
    ledG.off()
    ledR.off()
    ledB.on()
    time.sleep_ms(250)

Project 1: read Acceleration from Arduino Nano ESP32 board

solution Project 1: Read Accelerometer and Gyro

import time
from lsm6dsox import LSM6DSOX

from machine import Pin, I2C
lsm = LSM6DSOX(I2C(0, scl=Pin(13), sda=Pin(12)))

while (True):
    accel_data = lsm.accel()
    print('Accelerometer: x:{:>8.3f} y:{:>8.3f} z:{:>8.3f}'.format(*accel_data))
    gyro_data = lsm.gyro()
    print('Gyroscope:     x:{:>8.3f} y:{:>8.3f} z:{:>8.3f}'.format(*gyro_data))
    print("")
    time.sleep_ms(100)


solution Project 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- 

#Example usage for Arduino Nano
from machine import Pin, ADC
from time import sleep

analogPin = ADC(Pin(26))

while True:
  analogVal16 = analogPin.read_u16()
  print(analogVal16)
  sleep(1)

Project 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 2.2. For this, install everywhereml: 

pip3 install -U everywhereml

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)
