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.
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
Insert the shield's male header pins in the matching female header pins on the Arduino.
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.
Build the circuit to convert 7.2V to 5V on the 1" round PCB as specified in the schematic.
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.
