Quick answer

The LED Diamond block is a snap-in module that lights up when placed correctly in a Circuit Blox circuit. Pay attention to polarity and secure connections to avoid flickering.

Why polarity matters with the LED Diamond

Like most LEDs, the Diamond block has a positive and negative side. Reversing it won't damage the module, but the LED won't light. Look for the small polarity markings on the block and match them to your circuit board's orientation.

If you're using the block in a larger build, double-check that the power source is turned off while inserting or removing the module. This prevents accidental shorts and extends the life of the component.

Common build scenarios

The LED Diamond works well as a status indicator or decorative light in any Circuit Blox project. It pairs naturally with sound-activated or motion-triggered blocks for interactive effects.

Because it's a single-piece module, you can swap it in and out quickly during testing. Keep a spare on hand if you're experimenting with multiple layouts.

How to use the LED Diamond block

  1. Check polarity: Look for the + and – marks on the LED Diamond block. Align the positive side with the positive terminal on your Circuit Blox base board. If the LED doesn't light, flip the block 180 degrees and try again.
  2. Snap into place: Press the block firmly onto the board until you hear or feel a click. Ensure all prongs are fully seated in the slots. A loose connection causes intermittent flickering — reseat the block if needed.
  3. Power on and test: Turn on your circuit's power source. The LED should glow steadily. If it flashes or stays dark, check the battery level and all connections. Dim light often means low batteries; replace them before troubleshooting further.
  4. Combine with other blocks: Add the LED Diamond to a sound-activated or touch-sensitive block for interactive effects. The module works with any standard Circuit Blox base. Always turn off power before rearranging blocks to avoid accidental shorts.
