Step 1: Watch the Video!
I have explained everything in detail in this video from the basics to the build. There is even a light show at the end which looks completely awesome!
Step 2: Order Your Parts!
You will need these for the build:
2 LM324 ICs.
7 N channel Mosfets. (I used 55NF06)
2 Solderboards of the same size.
LEDs (the number depends on your choice of word, I used 60 LEDs.)
IC sockets.(not mandatory but better if used).
1 47uF capacitor.
9 10K resistors.
1 51K resistor.
3 4.7K resistors.
2 100 ohm resistors.
6 1K resistors.
1 6.8K resistor.
1 2.2K resistor.
2 3.3K resistors.
1 Buck Converter / 500 ohm resistor(not recommended).
Step 3: Build the Circuit!
Complete the LED sign first and test it. Next do the electronics part keeping everything jam packed. Firmly fix the 2 PCBs together with nuts and bolts. Make sure no solder connects with the solder on the other side.
Step 4: Enjoy!
That's it! You have made your very own VU Meter!
