This project transforms an Arduino Uno R4 WiFi into a WiFi-controlled motor system using the DroidPad app.

It enables joystick-based movement, button toggles, a speed slider, and even a self-driving mode using ultrasonic sensors. The Motors are controlled using the Arduino Motor Shield Rev3.

The system communicates over TCP, allowing seamless real-time control.

• WiFi Connectivity : Uses ESP32 (Uno R4 WiFi) to host a TCP server.

• Joystick Control : Control movement via an 8-axis joystick.

• Button & DPAD Support : Supports additional input actions.

• Slider for Speed : Adjust the speed dynamically.

• Self-Driving Mode : Uses ultrasonic sensors for obstacle avoidance.

• Motor Control : Smooth forward, backward, and turning motion.

• Easy Debbuging : Serial prints for DroidPad interaction with IDs.

• Customisability options : Easy layout adjust thanks to the DroidPad app with unique IDs for everything.

1. Clone the Repository

   git clone https://github.com/Klixxy/ArduTank.git
   

• Upload the Code to your Arduino using the Arduino IDE.

• Monitor Serial Output for the WiFi details.

• Connect & Control via DroidPad!

1. Download DroidPad: GitHub Repository

2. Connect your device to the Arduino's WiFi network.

3. Scan this QR code with the App to get a ready to use template:

3. Optional: manually enter the following settings in the app:

   • Type: TCP
   • Host: (Check Serial Monitor for IP)
   • Port: 8080

4. Add controls and give them IDs (only if you do it manually):

   • 1 D-pad (Default ID)
   • 1 Switch (Default ID)
   • 1 Joystick (Default ID)
   • 1 Slider (Default ID, Max. value 10)
   • 2 Buttons (changed IDs because there are two of them: button1 and button2)

5. Connect by pressing the small play icon.

6. Start controlling your car or tank! 🎮

Motor Pins as of the documentation of the Arduino Motor Shield Rev3.

Every Pin can be changed, if you have different Hardware.

In this version the Pins 1 and 2 are Outputs for Light and a Horn, hence the toggle on one Button.

• Arduino Uno R4 WiFi
• Arduino Motor Shield Rev3
• 2 x DC Motors
• 2 x HCSR04 Ultrasonic Sensors

• Check the Serial Monitor (9600 baud) for logs.
• Ensure DroidPad is connected to the same WiFi.
• If motors don’t respond, check wiring & power supply.
