WS2812B LED Wifi control with music visualizer Rev. 03
I designed this PCB to be used with a project from Instructables to build a sound reactive lamp. Take a look at the project if you want to build it for yourself: https://www.instructables.com/id/Wireless-Music-Reactive-Floor-Lamps/
As you see in the linked project, i changed the schematic a bit. I've added the sound detector to the lamp pcb and removed the controller completly. You have to modify the code to make it work. I've added a logic level shifter to get the signal up to 5V, which will suit the demands of the WS2812B logic.
The power supply connection is suitable for 1.5mm² or AWG16 wire. Solder them directly to the DC socket of your choice.
Mounting holes are for M3 screws. On the right side of the DC power supply pads are two additional M3 holes for securing the power wire with a cable tie.
Dimensions: 1.79" x 1.77" / 44.96mm x 45.47mm
Mounting hole seperation: 1.4" x 1.2" / 35.56mm x 30.48mm
I am using the following components:
1x 10V 4700uF electrolytic capacitor // example: https://bit.ly/2LRA8E6
1x 4 channel bi-directional logic level shifter // example: https://bit.ly/2F90OyY
1x 330 Ohm resistor 1/4W 5% // example: https://bit.ly/2AvTNFc
1x RobotDyn sound detector module // example: https://bit.ly/2FaPTED
1x single row 20 pin header 0.1" spacing // example: https://bit.ly/2AtS2bF
2x single row 18 pin socket 0.1" spacing // example: https://bit.ly/2TnzaSo
2x single row 6 pin socket 0.1" spacing // example: https://bit.ly/2scMWf2
For the LED and sound detector connection you have to split up the male pin header into pieces of 3 pins per header.
I recommend the use of max. 144 WS2812B LED. The maximum current draw is about 8.7 amps for the LED's.
