I'm planning to do a simple DIY car that is controlled with a smartphone. I'm new to DIY electronics, and would like to get all of the needed electronic components with a single order. Could you check out this list and tell me if i'm missing anything essential?

  • RPi3B
  • 2x DC motors
  • Motor controller
  • Power supply or batteries
  • Non-electronic stuff (4x wheels, chassis etc.)
  • Wires (What type of wire should I buy?)

As i have understood the RPi3B comes with onboard WiFi and bluetooth and has the ability to setup a hotspot, so all I need is a smartphone and programming skills for a wireless connection (?)

  • Does your motor driver support controlling 2 motors?
  • Have you thought about talking to your motor driver(from the Pi)?
    • keep in mind the Bluetooth does use up the Pi's UART! (see comments for more information)
  • For quick wiring, those are great, either many of them, or in bulk like the one I just found(you could also tear them apart when needed)
  • For solid constructions, you should consider soldering classic copper wires as well as getting connectors, to not have to solder to your components directly
  • Yes, the Pi3 has WiFi and BT, but you only need 1 of them for your remote control, unless the Pi itself is supposed to be controlling the car remotely
    • e.g. Smartphone -> Wifi -> Pi -> Bluetooth -> RC car

Regarding programming, you would need to write both sides on your own, a smartphone app, utilizing either BT or WiFi and the Pi's response, which will be talking to your motor driver.

Every thing is fine just for a simple car. If you want you can add some LED's . And in case of wires use Jumper Wires
