Introduction: How to Make an LED Input/clip Indicator (plus Light Show) for Speakers in 3 Insanely Easy Steps. (CRAZY Easy)
Don't you just hate when you can't tell if your speakers are overloaded or not. this can tell you if they are! (this is very dynamic to the speaker, as the bigger the speaker, the less power that goes to the LED)
Step 1: Materials
you will need few materials for this.
1 high power large LED. if you don't have that then use two or three regular LED's (depending on the power of your transmitter, computer LED's suggested)
LED wire (optional)
a stereo or some audio transmitter
Step 2: Connecting the Led (s)
Get your speaker and LED's and connect the positive side of the led to the positive side to the speaker input. do the same for the ground side of both. (if you don't know what side of your LED is positive or ground, test it with a battery or low power power bank. you may have to soldier some wires to the LED(s))
if you have a bookshelf speaker, do the same for the terminals of your speaker. MAKE SURE ITS FIRMLY CONNECTED!!!!!!!
Step 3: Connecting the Speaker to Your Stereo
im pretty sure you know how to do this
Step 4: TEST IT!
turn on your transmitter and turn it up!
if the LED's blow or get darker, this means your clipping. (you really need to turn your music down if it blows the LED's)
Step 5: Why Does This Work
Sound signal is actually just a highly fine tuned version of AC current. And LED's are built to handle high stress situations (such as strobing and fast changing power input, aka audio) on a low power input (aka audio... again), so an LED is perfect for situations like this. and remember, the size of the speaker depicts how much is going into the led (a bigger or more high power speaker takes more energy so less power goes into the led and vice versa.) making it accurate with any speaker, it also provides for a cool light show in the dark.
