I want circuit diagram for controlling the Dc motors with remote control. Range of control can be about 5meters.
Lets assume you are using 2 arduinos and 2 X-bees:
That's it for wiring. Now, if you are using an arduino at 5v, it may be wise to add some 10k resistors to your connections or use an X-bee shield that does level shifting from 5v to 3.3v. Personally, I have always just used resistors and never had a problem.
From there, it is just a matter of writing code for each arduino so one is a transmitter and one is a reciever.
Thank you chris but what i am trying to make is a quadcopter which flies in air and its control is on the wireless remote.
Ok, to do what you want to do, you are going to need to learn quite a bit. You need to start very simply and then, as you learn, make things more complicated. No one here can "tell you how to make a remote" unless they build and code it for you. Before you go any further, you need to ask yourself a question:
Do you want to learn about the hobby of robotics and work to your goal, or do you simply want a remote control for your quadcopter? If you just want a quadcopter, great! Go buy one. If you want to get into electronics, Great! --But you are not going to be building remotes for quadcopters anytime soon. This is like asking someone to tell you "how to build a car". --There are MANY MANY small steps you must take to get to your goal.
Now, if I have not scared you off, welcome to the hobby of robotics. The first thing to do is get an Arduino, a breadboard and a LED. Get that LED to flash on-and-off and you are on your way.
Chirs! I am electronics engineering final year student an i am familiar with the electronics components and am able to design different instument as well. But here I am seeking help only for the remote control which should be wireless.
Ok, do you speak Arudino? Do you know Picaxe basic?
Have you ever written code for a micro controller before?
Yes, I can write codes for AVR Atmega
Have you ever send data via a serial connection?
yes ofcourse i have done LCD interfacing and manymore
Add an xbee on each end, add a couple joysticks to the transmitting Atmega and send off the values.
which sensor may i use to transmit the data from main PCB to remote control
