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

Picture of 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

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

Yes, but you would have to be more careful of weight balancing :(

Great project and you presented it well. You could easily get this published in a hobby magazine such as "Make" or "Nuts&Volts".

This has excellent documentation. Brings me back to my college lab project days. Nice job :)

BlueSMiRF is extremely expensive. If you look on ebay you can get a jy-mcu bluetooth module for less than 10$.
