I need an Arduino code that is capable of keeping 3 different times. I'm using Arduino Pro Mini 328p 3.3V, an SD shield (I have represented them in the block diagram) and a Nokia 5110 LCD.
Users should select one option from the 3 option menu, and then stopwatch starts to keep time (in hours and minutes only) and writes to SD card.
The code must fetch the previous time data and adds on until the user presses the reset button. If the user presses the reset button, the code must reset the timer and also update the data on the SD card.
You don't need to write code for LCD, I need only the timekeeping and SD card code.
Waiting for your bids.
