Tasks

Project 0: connect a Arduino Nano ESP32 board

• Install the basic software https://labs.arduino.cc/en/labs/micropython
• connect the board via USB
• Make the orange LED (pin 6) blink using micro python https://docs.arduino.cc/micropython/basics/digital-analog-pins/
• Connect an external RGB LED (pin 2, 3, 4), https://www.sketching-with-hardware.org/wiki/RGB_LED
• Control the external RGB LED (on, off, mix color, brightness)

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()

25     time.sleep_ms(250)

Project 1: read Acceleration from Arduino Nano ESP32 board

• read data from the accelerometer and the gyro and print them (Arduino IDE) https://docs.arduino.cc/micropython/basics/board-examples/
• extend you program to write the data from the accelerometers to a file, https://www.sketching-with-hardware.org/wiki/FileIO
• transfer the file to your computer
• optional: add the photo resistors to your board, read their values, and write them to the file, too, https://www.sketching-with-hardware.org/wiki/LDR

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

• connect the board
• install the Juypter Notebook, https://www.sketching-with-hardware.org/wiki/Jupyter
• read the accelerometer and the gyro and show it in the 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

• use https://github.com/eloquentarduino/everywhereml to detect the same gestures as in 2.2

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)
