Create A Giant Meter Using Arduino

The Meter

The whole idea of this project was to create a giant meter to show website response time almost like a speedometer would. The result is something that’s both fun to watch and provides a meaningful ‘heartbeat’ of current status. After several revisions and different designs along the way, I ended up with what you see here.

Construction & Design

The meter is carved using my CNC machine from 1/4” bi-color HDPE (12 inches square). This is a great material to cut signs or other carvings with because anything carved out is the alternate material color, so there’s no painting/masking/re-painting needed. The needle is cut from 1/8” orange acrylic which worked great for the speedometer theme. For mounting the micro servo, I designed a hole matching the shape of the outer plastic casing which the servo I chose had (see parts list for a link). I designed the whole thing using Inkscape and Easel, mainly because they are free and fairly easy to use. Check out my bill of materials if you are interested in using the same HDPE and acrylic.


I decided to power the meter using the Arduino Uno microcontroller since it handles servo control really well. The Raspberry Pi would be another option, but I’ll detail the Arduino setup for now. My implementation also uses a few LED displays to display detailed metrics, but the servo is the main piece you need. Here’s a quick parts list:
