Circular LED Bargraphs - Yellow

These circular LED displays are a lot of fun. Essentially, these are what you would get if you could 'wrap' one of our LED bargraphs around a circle. They consist of 16 yellow LEDs arranged so that each quarter of the circle has a common ground and four anode pins, resulting in 20 pins total on the device. Because they're simply a bunch of cleverly packaged LEDs, they're just as easy to use as our LED bargraphs. These are great for indicating the position of a rotary encoder!

  • 16 Yellow LEDs
  • Max Forward Voltage: 2.4V
  • Dominant Wavelength: 585nm
  • Continuous Forward Current: 25mA

Circular LED Bargraphs - Yellow Product Help and Resources

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    Why is this $1 less than the other colors?

      The red is even cheaper, actually. Might be price differentiation from the manufacturer, passed on to us :)
      ( This read 'is the same price' - I must be going blind, it's actually cheaper. )
