Hi guys! So for my electronics class this year we were tasked with creating some kind of electronic gadget in order to demonstrate what we learned over the semester. Being a car-loving type of guy, I decided to get a cheap RC car and see in what ways I could hack it using an Arduino Leonardo I had leftover from lab. Having an infrared proximity sensor handy, I thought It would be nice to use the sensor to brake the car whenever It got too close to crashing into a wall. I'll try to be as clear as possible in case you guys want to build something similar or in case it'll help with one of your projects. 

Step 1: What You'll Need

Here's a list of what I ended up using for this project.

• Arduino Leonardo (or equivalent) with mini-USB cable
• Computer with proper Arduino programs installed
• Remote Controlled Car
• Sharp Distance Sensor 2D120X  (Infrared Proximity Sensor)
• SN754410 H-Bridge
• Heat Sink for the SN754410 H-Bridge
• Oscilloscope (plus Voltage Probe) or Multimeter
• Breadboard (for prototyping)
• Philips Screwdriver
• Wire Cutters
• Wire Strippers
• Electrical Wire
• Perfboard (for the final circuit)
• Solder and Solder Gun
• Hot glue gun
• 2x 9v Batteries (one for the Arduino and one for the Remote Control)
• 4x AA Batteries (for the car)
• Helping-Hand tool (optional)
• Alligator Clips (optional)
• Zipties (optional)
Can i so the same thing with a Ping))) sensor
Would I be able to use a Raspberry PI in this project? If so can you do a tutorial
Use a lipo (2s) instead of the 9v
thanks for sharing this here it's really informative soon I am going to fix it into my <a href="http://www.nitrotek.se/radiostyrda-bilar.html" rel="nofollow">RC car</a>,
Could you also make this mod for a RC helicopter?
This link may give you a good track to change the controls of a helicopter<br> <br> <a href="http://www.instructables.com/id/Nunchuk-controlled-Helicopter/" rel="nofollow">http://www.instructables.com/id/Nunchuk-controlled-Helicopter/</a><br>
Yes, but you would have to be more careful of weight balancing :(
Great explained thank's
Well done!
Great project and you presented it well. You could easily get this published in a hobby magazine such as &quot;Make&quot; or &quot;Nuts&amp;Volts&quot;.
This has excellent documentation. Brings me back to my college lab project days. Nice job :)
Since you built this on a low-end RC, I have to wonder if it would still be effective at moderate or high speeds.
Very well written and well explained looks like you enjoy electronics
BlueSMiRF is extremely expensive. If you look on ebay you can get a jy-mcu bluetooth module for less than 10$.
