Apparently, you can get curved bar graph LEDs, but only if you buy a fairly large quantity. Hand soldering discrete LEDs at the perfect angle would be frustrating, but with a 3D printed jig, it ...

The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for… ...

At a Glance If you are starting out with microcontrollers & electronics, breadboard-friendly switches & potentiometers come in handy. Discrete LEDs make great output devices, but LED bar graph & ...

The Mini Single Bar Graph Display is a universal display containing a 10-LED bar graph to indicate the vehicle’s battery status. The top or bottom LED’s blink to indicate HIGH VOLTAGE or LOW ...

I recently built a simple electromagnetic field (EMF) detector based on a code by Christian Figge that I found on the web. My design includes a 10-LED bar graph (from eBay), which I used to display ...

This Design Idea is a 1-dot bar graph display that provides a simple, compact, low-cost, and low-power alternative to the usual four-LED bar graph battery gauge [1]. It consists of a surface-mount ...

The blue, GaN LED bar graph dissipates 105 mW and requires a dc forward current of 30 mA, peak forward current of 200 mA and reverse voltage of 5V. KINGBRIGHT CORP., City of Industry, CA. (909 ...
