If you however wondered just how fast your car really is, you might be interested in this DIY Arduino G Meter which has been created using a Arduino with an accelerometer and a small LCD display to show the results.
Once attached to your car you can then see just how much G your experience at full acceleration. The creator of the Arduino project explains more about its inspiration and construction.
As an automotive enthusiast and a mechanical engineer, I had a poor physical understanding of G’s. Sure, I’m experiencing 1g as I’m standing upright, but how many G’s did I experience as I came to a quick stop in LA traffic? To gain a better physical understanding of G’s, I built this device. The accelerometer module was attached to a relatively level surface in the car using masking tape. The device is powered via the car’s USB port.
The device has two modes that can be cycled through using the push button. Mode 1 displays instantaneous values. Mode 2, shown in the picture, displays maximums. Maximums are reset by holding the push button for 2 seconds.
Braking from 25-0 mph, a maximum of 0.9g was recorded. Accelerating from a stop, a maximum of 0.49g was recorded (likely the initial “punch”). For cornering, I took a couple of quick turns in an empty parking lot and recorded a 0.65g without any tire squeal. Body roll contributes to these numbers.
The LCD Attachment Interface was cut from cardboard and glued to the Enclosure Lid. The LCD Module and the Arduino Nano were then glued to the LCD Attachment Interface. The Push Button was glued to the other side of the Enclosure Lid. After hooking up the jumper cables, the enclosure was closed and hot glued shut.
