Randy Sarafan, who also happens to be the Technology Editor over on Instructables, gutted a remote-controlled car and swapped the parts for an Arduino board.

The setup requires an Avatal 3117 remote start, an iPhone breakout board, an Arduino, a switching supply cell charger and a handful of transistors, resistors and diodes.

The Arduino code tells us that the valves will be opened as long as the remote up/down channel is above/under given values.

Witness how to create a powerful long-range remote control using Arduino technology. This guide takes you through the process of building a customizable, multi-channel RC system that offers ...

The infrared remote control might not hold the seat of honor in the average home theater setup that it once enjoyed, but it’s not quite out to pasture yet. After all, what are you going to us… ...

The system makes it feel as though you are sitting behind the wheel of the smaller remote control car and is powered by an Arduino Uno along with an IBT-2 H-Bridge to control the 24V motors.

But if your car doesn't have a remote ignition, you can build your own remote start system that responds to a text message from an iPhone.
