Introduction: Safe and Sound Security System
For my first ever instructable I've decided to create a sound reactive light security system for the Deaf and Hard of Hearing. It is meant to be adjustable with its parts as well as placement. You will be able to place it anywhere viewable. It works as a backlight but when there is a loud and abrupt sound it will alert you.
Step 1: Step 1: Gather Your Materials
Arduino Uno Board & USB Cable
9V Battery Clip with 5.5mm/2.1mm Plug
Sound Impact Sensor
Lots of Velcro Patches
Step 2: Set It Up on the Breadboard
You will want to follow this code from GraziCNU's Sound Reactive LED Strip.
Step 3: Move It Over to Your PCB
I moved the parts to mimic how they were set up on the Breadboard over to the Circuit board. I soldered the positive charges together on the LED and all of the negative charges together making sure I did not intersect the two charges. My desire was to make it as interchangeable as possible hence the velcro for easy assemblage.
Step 4: Watched It Go
Made sure everything was in working order once I plugged in the battery. If everything is working properly the LEDs will react to louder volumes. Adjust the sound sensitivity to your desired setting.
Step 5: Placed It in the Right Setting
You can place it virtually anywhere! I chose to put mine behind the television.
We have a be nice policy.
Please be positive and constructive.
