About This Project

<br>

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.

<br>

📌 Features

<br>

• 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.

🔧 Setup & Usage

<br>

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!

<br>

App Setup (DroidPad)

<br>

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:

<img src="https://github.com/Klixxy/ArduTank/blob/main/images/DroidPad.png" width="300" heigth="300">

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! 🎮

🔌 Wiring & Pin Configuration

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.

| Component | Pin | | -------------------------------------- | ---------- | | Motor A Direction | 12 | | Motor A PWM | 3 | | Motor A Brake | 9 | | Motor B Direction | 13 | | Motor B PWM | 11 | | Motor B Brake | 8 | | Button 1 (only on if pressed) | 1 | | Button 2 (toggled if pressed) | 2 | | Ultrasonic Sensor 1 (Trigger/Echo) | 7 / 6 | | Ultrasonic Sensor 2 (Trigger/Echo) | 5 / 4 |

<br>

🛠️ Hardware used (can be adjusted as you need)

<br>

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

<br>

🛠️ Debugging Tips

INFO: for further configuration and usage of IDs please see the Documentation of DroidPad

• 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.
