Due to the lack of Arduino components, I haven’t started using Arduino. I have done some researches for different functions of my prototype:
General resources for colour sensor
There are different approaches to achieve the function, and I will be focusing on using TCS230 to accomplish it.
The material is quite expensive and complex. However, with the Pixy2 Camera, colour recognition can also be achieved.
There are little arduino components that can identify shapes, and the suggestions from the tutor is to do image recognition through a software and send the data to the Arduino.
The simplest way to recognise voice
This method uses the software on the laptop to process the voice, instead of the material itself.
FTDI convertor (200inr) , arduino uno(400 inr) , Geetech voice recognition module (1800inr)
This approach is complex and requires many materials.
Elechouse V3 Voice Recognition Module
I will be focusing on this approach since it is relatively straightforward.
