What features can I add to my RC car?

In this tutorial we're going to look at some basic want

 

  • How to add control to an rc car
  • How to add LED lighting to an rc car

 

This is useful for people who want to modify an existing RC car too as it shows you how to add head lights, indicators, brake lights and revese lights to your radio controlled car. There are simpler way's to do all these things with basic components and without the need for the pic microcontroller. 

There are many other features which can be added to your car such as linear actuators or servos to make the car jump or hop like in this video lowrider '75 Caprice RC hopper car

If you've any ideas for rc car mods post in the forum and we might be able to help. 

Why would I want to make an radio controlled car from scratch?

The main reason in my view is that it will be unique, the only one of it's kind in the world. Your the one who decides what kind of lights you want on your rc car and how you want them orientated and controlled. so you have the satisfaction of knowing you built it and it does exactly what you want your RC car to do.

RC Shelby Cobra

As you may have guessed the plan here is (well supposed to be) simple. I've got a revell model kit of a 1967 Shelby Cobra 427 S/C and I plan to build a control system using an old radio controlled aircraft controller along with a PIC microcontroller to control the car and hopefully some LED lights if we haven't run out of power by the time we get that far.

Components used

 

  • Shelby Cobra 427 S/C Plastic Model Kit
  • Old RC controller, receiver and servo. I took mine from a radio controller plane.
  • pic 16f627
  • SN754410 = Motor Controller
  • 74HCT04N = Inverter Gate
  • 74HCT4066N = Analogue Switch
