I have DC motors

Ok I have a dual-H driver, I don't know why I said quad,;)
and ok thanks for the help!
2  Using Arduino / Motors, Mechanics, and Power / Simple Hobby Motor Code? Help. on: May 04, 2013, 02:34:36 pm
Ok so here's the setup, I have 2 hobby or dc motors, 1 in the back for forward/backward and 1 in the front for steering left and right. I just started arduino so Im still in the noob range, but what I had in mind is to control how far or how long each motor will run and then repeat so it runs on a pre-programmed track almost. For example, I would like it to go forward using the forward/backwards motor for say 3 seconds on a certain speed and then turn left using the left and right motor for a certain time on a certain speed then going forward again to achieve that turn. Is there already a code like this? As well, I would like to use a Quad-Half H-driver or Quad-H bridge how ever its spelt.

Thanks!

3  Using Arduino / Project Guidance / Sharp Infared Proximity Sensor Robot? on: April 29, 2013, 07:36:58 pm
I recently bought 2 hobby motors, an H-bridge and a sharp proximity sensor, Is there any site or code already written to make a self-avoidance robot?
Thanks!

4  Using Arduino / Project Guidance / Thermoelectric Cooler with Arduino? on: April 22, 2013, 05:31:08 pm
I know I need a thermoelectric cooler and a n-channel MOSFET but do I also need a heat sink? I'm going to use it to heat stuff up to its limits 180•C and to do this do I need a heat sink? It's going to be in an enclosure so they purpose is to act like an oven.
5  Using Arduino / Project Guidance / Arduino+Sparkfun Heating Pad? on: April 21, 2013, 07:07:19 pm
I recently bought 2 sparkfun heating pads and a NexxTech voltage regulator +5VDChttp://www.flickr.com/photos/94589858@N06/sets/72157633296011815/
Sparkfun Heating pads:https://www.sparkfun.com/products/11289
I am a complete noob at arduino so I have no clue what the code would be to program the arduino to work with the heating pads or even if the voltage regulator will work, so does someone know if this will work and if so, how would I set it up and program it?
Thanks!

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

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.

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

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!

ok thanks!
11  Using Arduino / Sensors / Muscle Sensor? on: April 17, 2013, 07:58:35 pm
 For my next project, I want to use a sensor to locate or track a muscle say in your biceps so when you're working out, you know what muscle is being used by an led which is either green or red depending if you are working that muscle. What sensor is this called?

Thanks,

12  Using Arduino / Project Guidance / Arduino UAV or Quad copter? on: April 15, 2013, 04:55:50 pm
I want to make an arduino uav or quad copter but I don't know what parts I would need, could someone tell me what parts I must have to have a fully functionally quad copter? Also where you can find each part and could you make one with an arduino uno smd or Leonardo?

Thanks for all the help!

ok thanks(:
14  Using Arduino / Microcontrollers / Re: Arduino Leo compared to a computer. on: April 10, 2013, 07:49:11 pm
For most home computers around 1980s? not sure for laptops or any portable computer back then thou and I would agree with CrossRoads, Fungus, ianphil397 and tim7
