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

This project by Joel Nadar demonstrates his journey to build a remote-controlled car using an Arduino Uno R3 and a TV remote. After we have noted the hex codes, we can upload them to the Arduino.

3D print and build an Arduino Pistol-grip Transmitter for controlling Remote Control cars.

This time, we’re building a 1:24-scale, fully-3D printed miniature RC Drift Car with cool underglow lights and a unique smoke effect. A fun, high-performance Arduino-based RC car that you can 3D print ...

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.

Assemble your own Arduino-based FPV headtracker to control a camera that moves with your head, letting you look around and observe your surroundings while flying or driving RC vehicles for a more ...

To some of us, hacking an RC Car to simply follow a black line or avoid obstacles is too easy, and we’re sure [Shazin] would agree with that, since he created an RC Car that follows your face ...

A perl script running on the iPhone will then send the command to the Arduino. When it receives the start command, the Arduino will ground the wire to the remote start and fire up the car.
