Question

I am coding and making a stopwatch using an LCD module and I am using buttons to stop and start the stopwatch. I was wondering when I start the code do I start coding the LCD module or with the buttons? Also, do I need an Arduino nano? Does it matter where you put something on a breadboard?

A) Start coding the LCD module first.
B) Start coding the buttons first.
C) You don't need an Arduino nano.
D) The placement on the breadboard can affect the circuit's functionality.

Answer 1

Starting with the LCD code in a stopwatch project can be more efficient for debugging, an Arduino Nano is suitable but not mandatory, and correct placement on a breadboard is crucial for circuit functionality.

Step-by-step explanation:

When creating a stopwatch using an LCD module and buttons, the approach to start coding depends on your preference and the specifics of the project. However, an effective strategy can be to start with coding the LCD so you can immediately see outputs and debug easily, then adding the button input functionality afterward. While you don't necessarily need an Arduino Nano, it is a suitable choice due to its compact size and sufficient capabilities for such projects. Finally, where components are placed on a breadboard is essential, as incorrect placement can prevent your circuit from working properly or even cause short circuits.
