Linear bargraph LED scale module KIT
Linear LED scale module with 12 LEDs.
Can be used as a voltmeter in a scale with independently adjustable limits in the range 0 to 5V (like 1V to 2V scale, 0V to 0.5V scale, etc).

Power supply: 8V to 12V
Graph: 12 red LEDs **, in dot or bar configuration
Graph orientation: top or side of the module
Input scale low limit: 0 to 5V (manually adjustable)
Input scale high limit: 0 to 5V (manually adjustable)
Dimensions after assembly: approx. 78.5x38.5x19 mm (LxDxH) (LEDs excluded)

** Want other colors? Tell us how many of what colors you want up to 12, in the comments at checkout. The available LED colors are: red, green and yellow.

Constructing an electronics KIT is very fun but involves working with a soldering iron and therefore presents some risk. We assume you have a reasonable common sense and some basic experience! Feel free to contact us for further information, here.
