Tasks

Project 0: connect a Arduino Nano ESP32 board

solution Project 0: 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 Project 0: 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()

Project 1: read Acceleration from Arduino Nano ESP32 board

solution Project 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 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- 

 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)

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

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)
