What is it?

This is a shield for an Arduino that makes building a TWANG super easy and robust. TWANG is an LED game inspired by the original Line Wobbler by Robin Baumgarten. This product includes all the unique hardware items you would need.

Complete details for building TWANG are on this blog post.

You can buy it in the following ways...

• As Partial kit as explained below.
• Fully assembled with 3D printed parts and programmed Arduino (you add power supply and LED strip)
• Ready to play will all parts and a 144 LED 1m Strip (WS2812b type)

Included With Basic Kit

• Fully assembled shield
• Door Spring
• Fully soldered, wired and labeled accelerometer module.
• Fully soldered and wired speaker.

Not included With Basic Kit

• The 3D printed parts
• an Arduino Mega
• an LED strip

What is new in version 2?

• Added audio output connector - The built in speaker works great for most environments, but at noisy events, the sound could use a boost. You can connect a powered, external speaker to this connector.
• Added large power capacitor - Some LED strips, like older WS2812, are very sensitive to lower quality power supplies that might spike the voltage on turn on. They recommend using a capacitor to reduce voltage spikes. This capacitor was added to the PCB so you don't have to add it externally.
• Removed life LEDs - Life LEDs were never installed on the version 1 PCB, but there was a place for them. The firmware uses the LED strip to show remaining lives. It also allows changing the lives per level without hardware changes.

Why did you make it?

The LED Line games are amazingly fun and challenging. They are a huge hit at parties and events. The game is easy to learn and very hard to master. My first one was hand wired and soldered. It worked great, but it was messy and prone to problems. I made the shield to make it super robust.

What makes it special?

It is very easy to build. You don't need an electronics or soldering skills. All soldering is already done. The board is clearly labeled and so are the wires.
