Summary of LEDs sync to music (with pics of my awesome computer case mod)
Summary: The article describes a quick, free project to sync LEDs to speakers using spare parts. In about 15 minutes the author built a simple transistor-based circuit powered from a computer molex connector, connected to audio via 3.5mm jacks, and controlled LEDs or 12V LED strips to flash with music.Parts used in the LEDs sync to music project:
- TIP31 transistor
- 4 LEDs or 12V LED strips
- Wire
- On/off switch
- 3.5mm jacks (1 male and 1 female)
- Solder
- Spare molex connector from computer power supply (for 12V)
- Soldering iron (tool)
- Wire strippers/cutters (tool)
Step 1: Materials
-TIP31 transistor
-4 LEDs or 12v led strips
-wire
-on/off switch
-3.5mm jacks (1 male and 1 female)
-solder
Tools:
-soldering iron
-wire strippers/cutters
Step 2: Build the circuit
Here is the circuit i used. For the 12v power supply i found a spare molex connector from the computer power supply and cut it. I used a multi meter to find which 2 was the positive and negative. (for me the yellow was positive and the black wire beside it was negative). Be careful when doing this and make sure the computer is off to prevent the risk of electric shock. (im not responsible if you get shocked or hurt). If you have any questions just comment below.
