Breadboard LED Indicator

Introduction: Breadboard LED Indicator

Another LED board? - YES!

While I was testing a LED driver board I needed something to quickly test the chip on a breadboard. I came to the conclusion that wiring up 8 or even 16 LEDs with individual resistors on a breadboard is a major nuisance. And we all know how easy it is to accidentally rip those cables out or how easily this grows into a bad mess of wires.

No more!

This board holds 16 LEDs + resistors. They're wired up in such a way that it can work in either common-anode or common-cathode configuration. Connect pin #9 to either +5V or GND. The 8 channels will then light up if they're connected to either GND or +5V. This board therefore works with push-pull outputs on microcontrollers, as well as with open-collector outputs.

Step 1: Schematic

Step 2: Make It

The 0805 LEDs are very easy to solder, just like the two resistor networks (1206) on the back side. Use plenty of flux and thin solder.

    Clever idea. I'm planning a general purpose "control panel" to go with a breadboard, this is an ideal way to include LED's. I'll definitely be using your schematic!
