Remember following tips restore your motor control system to lesson 1:

I suggest you run the sketch code in Lesson 1 and make sure motor connection is correct. This is very important for next steps.

Step 1: Connect the Uno board, model X motor driver board according below connection diagram.

Connect ENA wire from D3 to D9, keep wiring in D6,D7,D8,D11,D12 at the same position.

Step 2: Connect B_TX (in wifi shield)to D4 (in Arduino) and and B_RX(in wifi shield) to D5 (in Arduino) as per following picture.

Step 3: Insert Bluetooth Module into Osoyoo WIFI Shield Bluetooth slot as following graph.

Osoyoo WIFI Robot APP Search Google Play or Apple Store with the Keywords “OSOYOO WIFI UDP Robot Car Controller APP”

Step 1: Install APP into your mobile phone:
Go to your   Apple APP store and search APP name “OSOYOO imitation driving”, Download the APP as following and install it in your smart phone.

If you are using Android cell phone, please Download the APP from following link :


Step 2: Please download sketch from following link: ,Unzip the file and you will see a folder named tankcarV2.0-lesson7, then load the tankcarV2.0-lesson7.ino code into Arduino. (Notice: Shut off your battery or Unplug your power adapter when upload sketch code to Arduino.)

Step 4: Choose corresponding board/port for your project, upload the sketch to the board.

Drive your Robot Car

Now you have installed your hardware and software for this lesson, let’s drive our car!

Step 1)Put your robot car onto the ground and turn on the battery switch.

Step 2)Go to your mobile phone ->Setting ->Bluetooth setting and search a Bluetooth device called HC-02, pair it with code 1234

Step 3)Open OSOYOO imitation driving Robot APP, Click BT Search button and find the bluetooth you have paired

Step 4)Turn on Engine toggle, and When you rotate your mobile phone angle, your car will change direction.

Enjoy your driving!
