In this lesson, we will use Mobile to control our robot car and make an imitation driving. Since is a mock driving, we will use a virtual steering wheel and gear in our APP to imitate their counterparts in real car.
You must complete lesson 2 Basic Movement before you continue on with this lesson.
If you don’t complete the frame of car, please review lesson 1
If you don’t complete the basic wire connection, please review lesson 2
Connection:
Insert Bluetooth Module (VCC,GND,D2,D3) into OSOYOO motor shield as following graph (Remember: DO NOT remove any existing wires installed in Lesson2):
STEP 1:
Download https://osoyoo.com/driver/2022008400/lesson4.zip , unzip it, you will see a folder called lesson4
STEP 2:
Connect UNO R3 board to PC with USB cable, open IDE, choose corresponding board/port for your project.
Notice: Shut off your battery or Unplug your power adapter when upload sketch code to OSOYOO Basic Board for Arduino.
STEP 3:
Click file -> click Open -> choose code “lesson4.ino”, load the code into OSOYOO Basic Board for Arduino, and then upload the sketch to the board.
Notice: Servo Alignment
Please change the default value 90 in the following line as the FRONT value in the option 2 in Step 5 of lesson2. If you align the wheel direction manually as the option 1 in Step 5 of lesson2, please skip this step.
#define FRONT 90 // steering to front

Explanation of APP UI (UI is different between Android and IOS)
-
- Connect HC-02 bluetooth in Android phone. There is a BT Search button in Android APP: When click this button, you will see a Bluetooth device list which has been paired with your APP. Select HC-02 device to connect the car. Once HC-02 is connected, Bluetooth Status will change from Disconnected to Connected. You can only control your car when Bluetooth is connected.
- Connect HC-02 bluetooth in iPhone/iPad , simply click Connect button, a HC-02 device will show up in a pop-up list. Click that HC-02 device will connect Bluetooth module to your iPhone. Then the Connect button will change name to Disconnect.
- Engine toggle : When Engine toggle is set to OFF(white), car will stop and all buttons in the APP will be disabled. When Engine toggle is set to ON(red), car will start to move. All other movement control buttons will active.
- Forward/Backward gear switch: This gear switch can control the car is moving ahead or reverse like real car gear.
- F1,F2,F3,F4,F5 customized button. In this lesson, we only use F5 which pause the the car movement. The difference between F5 and Engine OFF button is that Engine OFF button when touched, all other buttons will be disabled. You should toggle Engine button again to enable other button. On the other hand, when F5 is clicked, the car will stop but all other buttons is still active. Even you do not touch any button just change your cell phone angle position(like you move the steering wheel), the car will move again.
- Direction Steering Wheel : When you rotate your mobile phone angle, the steering wheel will change angle as per your mobile phone rotation angle. This will make your car change direction. For example, when steering wheel make clockwise rotation, car will move to left. Remember, the steering and Forward/Backward gear should work together same as you are driving a real car. For example, when you want back your car to a right side packing lot, you need set Gear to R position and rotate your steer to count-clockwise direction.

- Speed+: Make the robot car speed up
- Speed-: Make the robot car slow down
Connect APP to HC-02 Bluetooth Module
- Connect with Android device:
If you use Android device and have not paired Bluetooth module with your cell phone, please pair the bluetooth module first before open the APP. In your cell phone Setting->Bluetooth ,find a Bluetooth device called HC02, pair it with password 1234.After bluetooth HC02 device is paired, open the APP. Click BT Search Button to connect APP to HC02 device.
- Connect with iOS device:
If you use iOS device, simply open the APP, click Connect button, you will see a Bluetooth list, select the HC02 device .
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, click Speed+ to make the robot speed up as the robot car is very slow at first. When you rotate your mobile phone angle, your car will change direction.
Enjoy your driving!
