- What are output devices?
Output devices receive signals from the Arduino and perform an action. Examples include LEDs, buzzers, motors, and displays. - How does Arduino send signals to outputs?
Arduino sends HIGH or LOW digital signals (or analog PWM signals) through its output pins to control these devices. - Which pins are used for output?
Digital pins (like pin 2, 3, 4…) are used for turning devices ON/OFF. PWM pins (marked with ~) are used for dimming LEDs or controlling motor speed. - Why are outputs important?
They show us that Arduino is working and reacting to inputs — like blinking a light to show a button was pressed.
