Output Devices
Group assignment:
Measure the power consumption of an output device.
Document your work on the group work page and reflect on your individual page what you learned.
Individual assignment:
Add an output device to a microcontroller board you've designed and program it to do something.
Electronic component output devices are components that receive signals or power from a circuit and convert them into a usable form of output, such as
light, sound, motion, or display. Here's a categorized list of common electronic output devices:
Types of OutPut Devices
Motion Output Devices
DC Motors
Motion Output Devices
DC Motors
Produce rotational motion.
Used in fans, toys, pumps.
Servo Motors
Precise position control.
Used in robotics, RC toys, animatronics.
Stepper Motors
Precise control of rotation in steps.
Used in CNC, 3D printers.
Solenoids
Linear motion devices.
Used for locks, punches, valves.
Visual Output Devices
LEDs (Light Emitting Diodes)
Indicate power, status, etc.
Can be single color, multi-color, or RGB.
7-Segment Displays
Display numbers (and some letters).
Available in common anode or cathode types.
LCD (Liquid Crystal Display)
Used for alphanumeric or graphical output.
e.g., 16x2 character LCDs, graphic LCDs.
OLED Displays
Thin, high-contrast displays.
Can be I2C or SPI based (like SSD1306).
TFT/IPS Displays
Full-color displays with better resolution.
Useful in GUIs for embedded systems.
Audio Output Devices
Buzzers (Piezo or Magnetic)
Emit a tone or beep.
Used in alarms, notifications.
Speakers
Used for complex sound or music.
Needs audio amplifiers to drive them.
Other Output Devices
Relays
Electrically controlled switches.
Used to control high-power devices with low-power signals.
Used in soldering irons, 3D printer beds.
Vibration Motors
Used in phones, handheld gadgets for haptic feedback.
Electromagnets
Generate magnetic fields for holding/lifting applications.
