Constant current LED driver 8 channels (PT4115)

• Constant current LED driver with 8 channels based on PT4115.
• Controlled by ESP32, for use with ArtNet protocol.
• Power supply from 8V to 30V (use suitable capacitor voltage) allow connecting several LEDs in series on each channel.
• Change 0.13R resistor to set max current (Current = 0.1/R).
• Some pin headers for future extensions, like servo to make a tiny moving head projector.
