    • *Cons:* Can have auto-shutoff features that interrupt power, limited to 5V output.

Always calculate your total current draw (each LED can draw 20-60mA at full brightness) to size your battery appropriately and avoid undervolting.

Wiring and Connectors

Proper wiring ensures reliability and safety.

  • **Wire Gauge:** Use appropriate gauge wire (e.g., 20-22 AWG for typical LED strips) to minimize voltage drop, especially for longer runs or high current.
  • **Soldering vs. Connectors:** Soldering creates the most reliable connection. JST connectors (SM, XH series) are great for modularity but ensure they are rated for your current.
  • **Heat Shrink Tubing:** Essential for insulating soldered joints and protecting connections from moisture and shorts.

Bringing Your Lights to Life: Programming and Control

This is where your creativity truly takes flight.

Software Libraries

  • **FastLED:** A highly optimized, powerful library for addressable LEDs.
