Summary of Make a Mini LED Siren powered by Arduino
This beginner Arduino project creates a mini LED siren with a fading and blinking LED alongside a speaker. It involves soldering wires to a button and speaker, drilling a hole in a ping pong ball to house the LED, and wiring everything on a breadboard connected to an Arduino Uno. The project demonstrates basic electronics concepts like controlling LEDs and generating sound with a speaker, making it ideal for those new to Arduino.
Parts used in the Mini LED Siren:
- Arduino Uno
- USB cable for Arduino
- Solderless breadboard
- Breadboard jumper wires
- LED (any color)
- Small resistor(s)
- Small speaker
- Ping pong ball
- Button
- Soldering iron
- Electrical solder
- Pliers
This is one of the first projects I have made with Arduino. It’s a little siren with a LED that fades and blinks on and off. It demonstrates basic use of LEDs and speakers. Also check out this article: 8-Pin Programming Shield
Constructive criticism is appreciated!
Let’s get started!
Step 3: Drill a hole in the table tennis ball
Step 4: Wiring it up
Get power to the breadboard:
Run a jumper wire from the Arduino GND pin to a breadboard “-” row.
Run a jumper wire from the Arduino 3.3v pin to a breadboard “+” row.
Wire the button:
Run one of the buttons wires to anywhere on the breadboard’s “+” row.
Run the other wire to an empty column on the breadboard.
Run a resistor from the button wire column to an empty column.
Run a wire from the resistor column to Arduino pin 7.
Wire the LED:
Stick the LED on to the breadboard. Slide each pin into a different column.
Run a wire from the positive LED column to Arduino pin 5.
Run a wire from the negative LED column to breadboard “-” row.
