I am in need of someone to write some code for me.
The sketch should be for an Arduino UNO with a SD-card module.
The program should compare the value which the user writes into the serial port, with the example text in the .txt file.
The text in the file will look something like XXX;X;123456789;123;123;
Every help is appreciated.
Is that the only text, or would you have to search 1,000 lines of a file to find it? Does the program do anything else? If so who will do the integration of this function with the rest of the functions? What happens when a match is found? What happens if it is not found? What remuneration range were you considering for this?
Does the user type something like XXX;X;123456789;123;123; exactly, or are they prompted to enter various values like XXX, 123456789, 123 etc and the data is combined to do the comparison?
The User has to write the exact thing like i have stated it. When its not found it should only display a message saying that it didnt find the value. For now it has to only go over like 10 of those variables. For the wage, its up to the person how much they would want and how fast they could do it.
Meaning, you want to consider bids privately?
I would say so, yeah.
What input device? A PC? Something else with a keyboard? A USB keyboard connected to a USB Host Shield? A custom keyboard controlled by the Arduino?
And if a match IS found?
Where is the message displayed?
So you expect the user to type exactly the full line
That needs to match a full line in the file?
If I enter only XXX it should not match?
If the capitalization is wrong, should it match?
If I forget the trailing semicolon, should it match?
Is speed a concern?
It’s pretty trivial to write but you need to be very precise on the expectations
Look up this tutorial Serial Input Basics - updated
then start by writing a very simple sketch which reads what has been entered in the serial monitor and tests to see if it is the same a known string in your sketch then outputs an appropriate message.
Progress from there. Hint: your test may have to deal with control characters at the end of the input string.
I'm guessing that this is leading up to interfacing a bar code or an RFID reader (or similar) up to an Arduino.
I'm further guessing that this is a school project.
