Proximity Unlocker

  03/2011    Experiment

  •  Technologies: Arduino, Nike+ Dongle

Inspired by this project posted on SparkFun, I hacked a Nike+ receiver to unlock my car door when I got near the car.

It took a fair bit of tuning so that the car wouldn’t unlock from half a block away, but it worked quite well. The hardest part was remembering to carry the transmitter with me.
