Whadda WPK05 I/O Module Instruction Manual

Introduction

The Whadda WPK05 I/O module is a versatile, stackable shield designed to expand the capabilities of your Arduino UNO (not included). It provides 6 relay outputs and 6 analog/digital inputs, enabling a wide range of automation projects. This module is suitable for both beginners and experienced makers. An example program is available for download to facilitate immediate use. The WPK05 is designed for easy self-assembly and seamless integration with your Arduino UNO.

Setup Instructions

Unpacking and Inspection

Carefully unpack the Whadda WPK05 I/O module. Inspect all components for any visible damage. Ensure all parts listed in the product packaging are present.

Assembly (if kit version)

If you have the kit version, follow the detailed assembly instructions provided separately with the kit. Ensure all solder joints are clean and secure. The WPK05 is also available as a fully assembled module.

Connecting to Arduino UNO

The WPK05 is a shield designed to stack directly onto an Arduino UNO board.

1. Align the header pins on the underside of the WPK05 module with the corresponding female headers on your Arduino UNO board.
2. Gently press the WPK05 module down until it is firmly seated on the Arduino UNO. Ensure all pins are correctly aligned and inserted.
3. Connect your Arduino UNO to a power source and your computer via USB.

Operating Instructions

Software Setup

To operate the WPK05 I/O module, you will need the Arduino IDE and the appropriate libraries.

1. Download and install the Arduino IDE from the official Arduino website.
2. Connect your Arduino UNO with the WPK05 shield attached to your computer.
3. Install any necessary libraries for relay control and analog/digital input handling. Refer to the Whadda product page or documentation for specific library recommendations.
4. Download the example program (sketch) provided by Whadda for the WPK05 module.
5. Open the example program in the Arduino IDE, select your Arduino UNO board and the correct COM port.
6. Upload the program to your Arduino UNO.

Using Relay Outputs

The WPK05 features 6 relay outputs. These can be used to control higher voltage or current devices (e.g., lights, motors) that cannot be directly driven by the Arduino's digital pins.

• Connect the devices you wish to control to the green terminal blocks associated with the relay outputs. Observe proper wiring and safety precautions for the voltage and current ratings of your devices.
• In your Arduino code, use the appropriate digital pins to activate or deactivate the relays.

Using Analog/Digital Inputs

The module also provides 6 analog/digital inputs. These can be used to read signals from sensors, switches, or other input devices.

• Connect your input devices to the designated input terminals.
• In your Arduino code, read the state of these pins using digitalRead() for digital inputs or analogRead() for analog inputs.

Power Considerations

Ensure your Arduino UNO and connected devices receive adequate power. The WPK05 module itself draws power from the Arduino. If controlling high-power devices with the relays, ensure the external power supply for those devices is sufficient and correctly isolated.

Maintenance

• Keep the module clean and free from dust and moisture.
• Avoid exposing the module to extreme temperatures or direct sunlight.
• Regularly check connections for looseness or corrosion.
• If the module is part of a permanent installation, consider housing it in a protective enclosure.

Troubleshooting

Module Not Responding

• Verify that the WPK05 module is correctly seated on the Arduino UNO.
• Check all wiring connections for continuity and correct polarity.
• Ensure the Arduino UNO is powered on and connected to your computer.
• Confirm that the correct board and COM port are selected in the Arduino IDE.
• Try uploading a simple "blink" sketch to the Arduino UNO without the shield to confirm the Arduino itself is functioning.

Relays Not Activating

• Check the power supply to the devices connected to the relays.
• Verify the digital pins controlling the relays are correctly defined and toggled in your Arduino code.
• Ensure the relay coil voltage matches the output voltage from the Arduino (typically 5V).

Input Readings Incorrect

• Check the wiring of your input sensors or switches.
• Verify that the correct analog or digital pins are being read in your Arduino code.
• Ensure the input signal voltage levels are compatible with the Arduino (e.g., 0-5V for analog, 0V/5V for digital).
