The Internet Controlled RC Car allows you to remotely drive around a small rc car from wherever you may be and see where it is going. This is fun because you can remote explore whatever space you leave it in, or hand over the keys - so to speak - and allow someone to drive around your space. This is also a great building block for a telepresence robot.

This project is also a great beginner project for someone who has made a few simple things and is looking to get slightly deeper into the world of microcontrollers. It starts to incorporate more advanced skills like circuit building and networking, but is not dauntingly complex.

Schritt 1: Materials

You will need:

(x1) RC car (RadioShack #60-875)
(x1) Wireless camera (RadioShack #55056398 - web only)
(x1) Arduinio Uno (RadioShack #276-128)
(x1) Seeed Ethernet Shield (RadioShack #276-241)
(x1) Rectangular PCB (RadioShack #276-150)
(x1) 1" round PCB (RadioShack #276-004)
(x1) 7805 5V regulator (RadioShack #276-1770)
(x1) 10uF capacitor (RadioShack #272-1013)
(x1) 0.1uF capacitor (RadioShack #272-135)
(x1) M-type jack (RadioShack #274-1582)
(x1) K-type plug (RadioShack #274-1567)
(x4) 5V SPST relays (RadioShack #275-232)
(x1) 6" x 4" x 2" project enclosure (RadioShack #270-1806)
(x1) 7.2V rechargeable battery (RadioShack #23-2183)
(x5) AA batteries (RadioShack #23-2212)
(x1) Ethernet cable (RadioShack #55058573 - web only)
(x1) USB cable (RadioShack #26-713)
(x1) Assorted zip ties (RadioShack #55066143 - web only)
(x1) Shrink tube (RadioShack #278-1627)
(x1) M3 nut, bolt and washer

Schritt 2: Insert the Shield

Insert the shield's male header pins in the matching female header pins on the Arduino.

Schritt 3: Remove the Cover

Remove the four screws from the bottom of the RC car keeping the top plastic cover in place, and put the screws aside for later reassembly.

Remove the top cover.

Schritt 4: Power Conversion Circuit

Build the circuit to convert 7.2V to 5V on the 1" round PCB as specified in the schematic.

Schritt 5: Plug

Attach a red wire between the 5V output on the power conversion PCB and the K-type plug's center pin.

Attach a black wire between ground and the outer jack connection.

Twist the cover on the jack shut to insulate it.

<p>so i searched for the wiring diagram, and figued out one that would work.</p><p>--------------------------------3----</p><p>1--------------------------------------4</p><p>---------------------------------2------</p><p>1 goes to the ground of what the RC remote uses for that functions ground. I.E. when you go forward, all the controler is doing is connecting a middle contact with another, and that same middle is used for reverse. so connect 1 to that common ground. then 4 will go to the contact that is specifict for that function. 2 goes to the ground on the audrino, i just connected them all together and poped it in the extra ground pin for the audrino. 3 goes to the designated pin on the audrino that gets the calls of High or Low. Feel free to send me a message if this isnt clear enough.</p>
<p>Hi, randofo.</p><p>Nice instructable. It's so good idea. I think also Ethernet to IR gateway solution as you. Because I have always been found where is TV remote-controller. </p><p>Your intructables will help me for making Ethernet to TV romote-controller.</p><p>Thank you.</p>
Smart idea! Do I have to use the same ethernet shield as you use? I have the original arduino ethernt shield, can I use it? And do I have to do any wiring differently?
<p>is this car is wireless ??? and if yes then how ??? i dun want to use Lan cable, it will b be its drawback</p>
<p>Do you have an electrical plan of the connection of your arduino, components and wifi shield? And also something like a H- bridge of your project? </p>
<p>is this car is wireless ??? and if yes then how ??? i dun want to use Lan cable, it will b be its drawback</p>
<p>IS this car without cable ??? or if not, then how to make it wireless ? with use of arduino wireless shield or what ?<br>please suggest i want it to b wireless, dun wan lan cable with it..it is its drawback</p>
<p>wiring diagram?</p>
<p>where is wiring diagram?</p>
<p>Hey man,were you able to get that wiring diagram? I kinda need it too, tnx!</p>
did you guys get the relay wiring diagram?
thanks i will try and send a result <br>
thanks i will try and send a result <br>
<p>is there any alternet option for ARD124B2P ethernet shield??????????????</p><p>should i use another ethernet shield</p><p>nd what will be change in program???????</p><p>plzzzzzz reply its very urgent</p>
<p>A quick question. where is the diagram mentioned in step 12 Wire it Up?</p><p>&quot;Wire the remote control board to the relay board as specified in the wiring diagram.&quot;</p><p>A really good solution with off-the-shelf parts!</p>
<p>Hey bro, were you able to get that wiring diagram you were looking for? I kinda need it too, tnx!</p>
<p>What if I use Aceduino aside from Arduino?Would that be okay?</p>
<p>What if I use Aceduino aside from Arduino?Would that be okay?</p>
<p>What if I use Aceduino aside from Arduino?Would that be okay?</p>
<p>I just read it out and really felt pleasure that such things can be made also . I'll try my best to make this for my brother he love toys and this is a advanced one </p>
<p>Question! I have a GoPro Hero 3 Black, can I use this as my camera or do I have to have a webcam? I want to find a small enough camera to fit in the RC I have without too much modification to the body of it as well as aesthetically pleasing to the eye. </p>
<p>you could use the gopro app for streaming</p>
you could but you would only be able to record and store to the go pro sd card. wouldnt be able to stream like a web cam
<p>Another question as well. Is there a way to change the Java script so that I may use my Keyboard instead of the page. I would like the driving to be pretty smooth. </p>
<p>Great project ! </p><p>Finally get to play with the Ethernet Shield I've had for a while.</p>
<p>This is an awesome project! The only thing I would recommend would be to cut and reconnect battery wires one at a time to avoid sparks and damaging batteries. Still this is a really great project, keep up the good work!</p>
<p>this is awesome. I can keep watch of my apartment while I'm away. Plus looks fun to mess around with. I'm gunna find a WRX remote car to match my Subaru. Thanks for the project post :)</p>
Roughly how much did everything cost?
<p>Just made a quick total of all said parts. It comes to $235</p>
<p>This is so cool man!</p>
<p>Thanks for sharing!!</p>
<p>非常棒!我想可以通过IO口和三极管还有上拉电阻 代替继电器。</p>
<p>How much lag do you get with that camera?</p><p>I tried making something like this once with a digital camera, but I had to replace it with an analog one to get rid of the lag on the video.</p>
<p>awsome project</p>
<p>Nicely done. </p>
<p>Wow man so cool brilliant stuff dude this really is a master piece, I am also going to build one by following the above steps, I am pretty much a disaster when it comes to creating something on my own, but lets hope my effort is a lot more fruitful this time around.<br><br>Robert From--- http://www.westcables.com/</p>
I want to drive it too! lol... nice job!
Really nice! I'm going to make this :)
