This project was a huge leap forward for me. I intended on using it as a tool to inspire youth in the local area to get into STEM. However, it advanced my knowledge of 3D print and design a ton.

3D Printing the STLs:

• Print the chassis face down. It looks better if you print it on painters tape. You get a matte finish.
• Print the motor mounts upright, it reduces the amount of supports needed
  
  

Code:

The code as well as the circuit is broken into multiple layers.

• Mechanical Layer
  • Arduino Uno R3 and Motor Shield
    • Responsible for controlling the motors
• Communications Layer
  
  • Arduino Uno R3 and Bluetooth
    • Responsible for accepting coms from RC Car remote and setting pins that communicate with the mechanical layer
• Controller Layer
  
  • Windows Phone
    • Windows Phone app that communicates via bluetooth with the Arduino communication layer.
