This experiment let's you: Use presets: Choose a button at the top to choose a number/letter and will be converted to segment display. You can play around. Choose clear to clear. Modify segments: Click on a segment or a binary digit at the bottom to turn on/off a segment, making a new digit. Change brightness: Click on the left to change brightness. Drag to the top for a full brightness. I'll have more features soon. FAQ ===== What are the letters A-F mean? - It stands for extra digits in hexadecimal, since we only use 0-9 by default.
