Arduino Controlled Party Lights

Introduction: Arduino Controlled Party Lights


My name is AJ Udom and I am going to give you a step by step guide on how to make a micro-controlled party light.

This is the overview picture.

This will be a fun, and fairly simple project.

Step 1: Gather Parts

First step is to get all of the parts.


- 1 Servo Motor
- 6 LED's (various colors)
- 1 Microphone
- 1 Arduino Uno
- 1 Breadboard.
- 6 Resistors
- Breadboard Wires
- Download Arduino (It's Free!)

Step 2: Connect Circuit Together

Step 1) Connect the LEDs and Resistors to the output pins on the Arduino.
(For example I chose pins 13-7. Note: Pin 12 is broken due to a broken breadboard wire.)
Pin --> Resistor --> LED --> Ground

Step 2) Connect the Microphone to the ground, 5V, and an Analog Pin.
(For example, I chose Analog Pin 0)
OUT to Analog Pin, GND to Ground, and VCC to 5V.

Step 3) Connect the Servo to Ground, 5V, and a PWM Pin.
(For example I chose PWM Pin 5)
White Cord to Input, Red to 5V and Black to Ground.

Step 3: Type Out Code

The code is fairly simple. The hardest part is figuring out when you want a different sensorValue to become a different set of lights. Because the lights act as a volume meter, then you will only want positive values for sensorValue. If you consider the halfway point (512) as 0, then you want an absolute value function as part of your code. My code can be found at this site.

Step 4: YAY!!! YOU'RE DONE!!!!

You have now completed your party lights. This is my finished product.

    I like it. Nice to see someone add a servo to the party usually it is just lights. I will have to check it out. Thanks for the code.
