  • Please note that you will encounter compilation errors as shown below: "Compilation error: WiFiNINA.h: No such file or directory". To solve this error, you need to install the library of  the WiFi "WiFiNINA". In Arduino IDE, choose "Tools" > "Manage Libraries" (as shown below). Under the library manager, search "WiFiNINA" and click the "Install" button to install the library as shown.



  • More examples of Arduino Nano RP2040 Connect and the built-in WiFi can be found on the Arduino IDE as shown below: "File" > "Examples" (choose any from the examples under "Examples for Arduino Nano RP2040 Connect" or "Examples from custom libraries").

Programming support of Arduino Nano RP2040 (ABX00053 / ABX00052):

 a) Arduino IDE: 2.3.x / 1.8.x / web-editor: C / C++ language 

- Please refer to the lab sheets.

 b) MicroPython: (no need to compile / flashing, No compilation / library compatibility errors) (Just run scripts)

  i) Official MicroPython reference website / Arduino website

 ii) Why MicroPython might be taking over Arduino IDE: 

  MicroPython Basics: What is MicroPython? (By Tony DiCola)

  Five 5 Advantages of Using Micro Python for Embedded Software Programming

  (YouTube video) Time to Say Goodbye to Arduino IDE and Go On to Micropython/ Adafruit Circuitpython?

- Eliminating the library/compiler installation or compiler-version-conflict problems with MicroPython / CircuitPython 

- Easier debugging (no need to compile & flash to debug - just type your command to debug)

Sensors & Actuators

They are probably available in the PolyU EEE IoT hardware labs: (first come first serve)

1) Buzzer modules (鸣器模块) https://item.taobao.com/item.htm?_u=iodb0t204a6&id=45312865305  

Please note that some buzzers can work with AC or periodic pulse signals only (not DC signals).


Please use the buzzer module with source (easier uses, no need of high-frequency pulses).

Ref code: https://esp32io.com/tutorials/esp32-button-piezo-buzzer   http://pan.baidu.com/s/1hqByZty

Tact switch circuits: (need pull-up resistor and serial protection resistor)

e.g. 

    https://learn.sparkfun.com/tutorials/button-and-switch-basics/all


The source means the sound vibrating sources. In case you are using the non-source buzzer module, you need to generate 2k to 5k high-frequency pulses. So it is recommended to use the buzzer module with source (有源蜂鸣器模块)

-----     -----      -----

2) Photoresistor-1 module KY-018 (光敏电阻模块)  

 https://pan.baidu.com/s/1VMFN1fVo5jxB80IYTsY67A   (password:   y8jw) - please download test program in Google drive

3) RGB Led tri-color module (三色LED模块)  
By applying analog voltages on R = Red, G = Green, B = Blue to display the LED in different colors.
With built-in small resistors on board, it is safer and more compact to use this than using external resistor network (better safety & small size).
4) Microphone module (声音传感器模块)      sound sensor

5)   Laser distance-measuring module GY-530 VL53L0X (激光测距传感器)     
https://item.taobao.com/item.htm?_u=kodb0t20541&id=551955373190   http://pan.baidu.com/s/1dEPYrIh

Ref: https://pan.baidu.com/s/13_WpuJZDb_K2oH_yewQhYw 提取码: 2frr


7) Ultrasound module new-version HC-SR04 (超声波测距传感器) 
      Note that we have different versions. Check below info from Taobao:

Taobao Ultrasound modules (it should support 3.3V) - RP2040 needs to solder a resistor to provide 5V, thus the low-voltage version or 3.3V version is preferred.


8)   DHT11 Humidity sensor modules (温湿度传感器模块)        


Ref: http://pan.baidu.com/share/link?shareid=388339&uk=322357029    ;      Google drive sample codes/info

Demo of Intelligent fall detection using TI mmWave radar sensors: YouTube video demo



14) Camera Modules
Actually, it is difficult and not recommended to add a camera for Arduino Nano RP2040, because of a lot of wire connections to troubleshoot, although it is still possible, using SPI or parallel bus.
a) Reference project: ECE4760 final-year project: rp2040 Camera



b) OV7670 camera used with RP2040

15) Additional Communication Modules
15a) NB-IoT Wireless Communication Modules (supporting MQTT, TCP, UDP, CoAP, etc)

NB-IoT service is available for only commercial customers in Hong Kong but we have sim cards that can be borrowed (quantity: ~ 50 units). We have some test programs and lab materials using BC28 / BC35 modules. One of the advantages is its low power and to access Internet without WiFi, especially in the outdoor area.
Please feel free to come to contact our technical staff (Patrick) in office hours.


15b) 4G / 5G Wireless Communication Modules 
e.g. 4G module from 01Studio:


To find the location (like GPS) and access the Internet.     YouTube demo videos

With Camera modules: MicroPython boards and custom-made AI (not using chatGPT)

5G Wireless module: RM500U5G (note: very high power consumption. Good to use low-power NB-IoT modules)
