Arduino Based Hobby Robot Project

First you need to download the documentation and base source codes from http://www.elegoo.com website for Elegoo Smart Robot Car.

Elegoo Smart Robot Car

Lesson 0 Assemble The Car

Lesson 1 Make The Car Move

Note: I use steps instead of continuously moving.

Lesson 2 Bluetooth Car

Bluetooth remote control with node.js app by SerialPort package, it use standard input/output for communication.

Arduino sketch: bluetooth.remote.control
Nodejs app: bluetooth.remote.control.nodejs

Turn on the vehicle,
Connect the HC-06 bluetooth device to your Macbook (System Preferences/Bluetooth, Default password: 1234)
Install dependencies - npm install
Start the node script by node index.js command
Now you can control your car by W,S,A,D + ENTER commands.

Lesson 3 Infrared Remote Control Car

Arduino software: Sketch -> Include library -> Add .ZIP library -> IRremote.zip

Moving by steps: infrared.remote.control.ino

Linux issue fix:

// avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied
$ sudo usermod -a -G dialout <username>
$ sudo chmod a+rw /dev/ttyACM0

Lesson 4 Obstacle Avoidance Car

Lesson 5 Line Tracking Car

Arduino Uno

Bluetooth

Tutorial: Cheap 2 Way Bluetooth Connection Between Arduino and PC

Sketches: /arduino.uno/bluetooth/

Tested with HC-06 bluetooth device on OSX. Follow above instractions from tutorial and when you connected your HC-06 bluetooth device to Arduino Uno and the sketch is uploaded. Open iTerm2 app on OSX.

Check your serial devices: ls /dev/tty.*
