Скачать или смотреть Using an Arduino Uno to control and flash LED Lights on a LEGO Fire Engine

Short story:
We take a look at both commercial and completely DIY lighting for your LEGO models, and control them with an Arduino Uno.

Longer story:
We have a look at different ways to light your models, firstly with commercially available set-specific lighting kits. After that, we cover some of the commercial plug-and-play DIY options, then have a look at completely DIY methods, involving soldering your own SMD LEDs and working with some very fine wire.
All of these had their advantages and disadvantages, which we also cover. Even the very installation of lights into your LEGO set has pros and cons. The lights can make a set look better, highlight details, or even put on a show. The flip side is that the model tends to be relegated to the shelf, with play being difficult. It also involves wires which will likely be visible at some point, and bricks which may no longer fit perfectly where the wires go.
We’ve chosen the Harry Potter Whomping Willow Set No. 75953 and The Pirates of Barracuda Bay Set No. 21322 to demonstrate the commercial kits.
After that, we use commercial DIY options to light the Vampyre Castle Set No. 9468, and fully DIY options to light the Haunted House Set No. 10228, and even give it a sound and light show with tour.
Finally, we get ambitious and make a full set of working warning lights for fire and other emergency vehicles, with multiple flash patterns using an Arduino Uno. Regardless of your electronic or LEGO skill levels and knowledge, there will be something in here for you.
