I dont know anything about arduino , my friend is asking something like this.
From what i understand, they want to creating something like reverse vending machine that would be using sensors for item detection if it is a can or plastic bottle, there will be equivalent points for thrown item (can/plastic bottles) so basically the quantity of thrown item is considered. Where should they store the equivalent points? is there something like SD cards on arduino for the storage of data?
For example the bottle/can thrown is 10 pieces then the equivalent points is 5points. Then the 5 points will be displayed on the TFT LCD.
My questions are:
-Can they store default data of equivalent points per item to SD cards? (something like a database?)
- How to retrieve and compare the equivalent points data from the arduino sensors? (If bottle is detected by the sensor, compare it to the equivalent points database and calculate the total points he will get and display to the TFT LCD screen)
