#003 LED Chaser

Blinks a series of 12 LEDs in a continuous loop.

The Build

Notes

There seems to a general mis-conception that resistors should be connected to the anode of a LED: not true.

This circuit simplifies things with a single resistor (1k is about right for the LEDs I used) on the common cathode part of the circuit. That’s fine in this case because we’re only going to have one LED on at any time.

LEAP is just my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know (or send a PR!). See the individual projects for credits where due.

For a while I have also included various scale modelling projects here too, but I've now split those off into a new repository. Check out LittleModelArt if you are looking for the modelling projects!
