These 10 segment bar graph LEDs have many uses. With a compact footprint, simple hookup, they are easy for prototyping or finished products. Essentially, they are 10 individual green LEDs housed together, each with an individual anode and cathode connection.
Note: The pinout on these bar graphs may vary from what is listed on the datasheet. Rotating the device 180 degrees will correct the change making pin 11 the first pin in line. We have contacted our supplier to correct this mistake in the future.
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.
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.

Make sure Pin 1 is an anode and not a cathode.
I recently purchased one of these and have been using it with my Arduino. I'v already ordered more. It works great and has saves be the time and frustration of having to deal with individual LEDs. It works great with the 330Ω resistor network. Just plug two networks in with the LED bar and your set to go.
