I'm astounded that some cars don't have a digital compass always visible. You either have to launch the navigation app each time which may even disappear when you adjust the radio. In this project, you'll create a digital compass that can be powered by by the cigarette lighter or another source (batteries make it handheld). You could buy one, but where's the fun in that?

TinyCompass

In this Instructable, we will be building a compass using the TinyShield Compass as well as the Circle Edge Led shield. Before starting, the proper drivers must be installed to detect the COM ports. These drivers must be installed before downloading any codes from the codebender plugin. The drivers needed can be found here. Lucky for us there are no downloads for this project, we can simply use the codebend ...

Steampunk Compass using Arduinio

Having built a few puzzle box games recently, and having some components left over I thought I would build a functional Steampunk Compass. Based around a Arduino Duemilanove this is a really quick and simple build. Taking reading from a digital compass the Arduino controls a servo to position a clock hand. Step 2: Connect the electrics. Couldnt be simpler. The digital compass connects; SCL to Arduino Analog ...
