Topic: Cheap Arduino RC Car? (Read 983 times) previous topic - next topic

I want to make an anonymous arduino car with no ping sensor just arduino, however the car I have or got is cheap and I got it from the dollar store and it has a 2007 New Bright R288-2 chip but it also says 0502 after R288-2 but there is a gap between these two numbers so its R288-2      0502 . Here's a couple of photos of the circuit http://www.flickr.com/photos/94589858@N06/8662186116/in/photostream/ and http://www.flickr.com/photos/94589858@N06/8661087627/in/photostream I can change the code that some else already made http://www.instructables.com/id/Autonomous-Control-of-RC-Car-Using-Arduino/step8/The-FUN-Part/ to work with my car or just wire it up to match the code. However this is my first time doing something like this so I don't know what to do with wiring it up, I know to wire the car's GND to the arduino's GND but how do I hook up the other things so that I can make it go forward, backward, left and right?

All help is extremely grateful!

You need to either make a H-bridge (motor driver) or buy one online. Look up Arduino motor driver, or Arduino H-bridge.

Or could I wire the H bridge from the circuit board itself?

Do you know where on the circuit board are the connections to the H bridge?

What does the circuit board do? Is it the complete radio receiver and controller all in one?

What are you planning to use the Arduino for? You used the word "anonymous" in your first post, but perhaps you mean "autonomous"? Will the Arduino replace the radio receiver and control the car as a robot? If so you will also need to control steering and, presumably, detect the car's position.

Yes sorry I meant autonomous;) The circuit board transmits the radio signal from the controller to control to servos, 1 at the top is to turn the wheels and the bottom one is to make it go forward and backwards. I don't care for the remote controller, I want to ditch it and just use it with the arduino and make a program to automatically do a preprogrammed course. I'm planning to use the arduino to just tell the motors where to go with a preprogrammed track. I plan to use the car as a robot and for the steering I can add a second motor in the code and create custom turns to do.

Are you going to measure the time (preset delay) in which the car turns or use an encoder to track the distance of how far the car goes to then decided when to turn?

Im going to measure the time(pre-set delay) instead of an encoder
