Question

Using an Arduino, you _______ to/from inputs and _______ to/from outputs?

1) send, receive
2) connect, disconnect
3) write, read
4) input, output

Answer 1

In using an Arduino, you 'write' to outputs and 'read' from inputs to interact with the device's hardware.

Step-by-step explanation:

When programming an Arduino, you typically write values to outputs, such as LEDs or motors, and read values from inputs, like sensors or switches. This is the fundamental way you interact with the Arduino's hardware using its digital and analog pins. Consider a simple project where you have a button and an LED. When the button is pressed (input), you 'read' the button's state. Depending on this state, you might then 'write' a high signal to an LED to turn it on (output).
