Functions

CarDriverShield - library class name, use to declare a user class for using library.

begin(int led_num) - CarDriverShield initial function. Must be called in setup() of arduino. led_num=-32768 means no LED is needed.

forward() - car run forward

backward() - car run backward

decelerate() - car run decelerate

accelerate() - car run accelerate

turn_left() - car run turn_left

turn_right() - car run turn_right

evt_loop() - CarDriverShield event loop, handle speed refreshing and LED control.

How to

This is a quick start guide, which aims to teach you how to use this CarDriverShield library and tell you what you need prepare for using.

Prepare

Assemble

  1. Plug your Arduino Nano into Car Driver Shield.
  2. Fix Car Driver Shield in your Toy Car.
  3. Parallel connect the two left side wheels, anode to anode, cathode to cathode, then connect the anode(+) of the left wheels to the OUTA-1 and the cathode(-) to OUTA-2
  4. Just do as part 3, parallel connect the two right side wheels, anode to anode, cathode to cathode. Then connect the anode(+) of the right wheels to the OUTB-1 and the cathode(-) to OUTB-2.
  5. Connect the battery.

Upload

  1. Download CarDriverShield.

     #get through GIT tools :
 git clone https://github.com/elechouse/CarDriverShield.git

    or

     #download zip file

  2. Extract the zip file if you download the zip format file. Copy CarDriverShield to $ArduinoSketch/libraries .

    Note: $ArduinoSketch means your Arduino sketchbook location, you can find it by opening ArduinoIDE->File->Preferences or shortcut Ctrl+comma

  3. Restart your Arduino IDE.

  4. Open car_driver_shield_sample0. (ArduinoIDE->File->Examples->CarDriverShield->car_driver_shiled_sample0)

  5. Connect your Arduino Nano to PC, select exact Serial Port, select exact arduino Board.

  6. Hit upload button, wait to be uploaded.

  7. Now you can control you Toy Car through serial port(Default : 115200,8,N,1),

Most people may need to control your car by wireless way, here is some recommended way:

Run your car

Control your car by sending these characters:

  • w --> forward;
  • s --> backward;
  • a --> turn left;
  • d --> turn right;
  • e --> accelerate;
  • c --> decelerate;
  • z --> stop;
