This bundle provides essential components for various electronic projects, particularly those involving microcontrollers like Arduino. It includes a set of multicolored Dupont wires and a 4-channel DC 5V relay module.
1.1 Dupont Wires
The ELEGOO 120-piece Dupont wire kit consists of three types of jumper wires: male-to-female, male-to-male, and female-to-female. These wires are flexible and can be separated to form custom assemblies, supporting both standard and non-standard pin configurations. They are ideal for connecting components on breadboards, prototyping shields, and microcontrollers.

1.2 4-Channel DC 5V Relay Module
The 4-channel relay module allows a microcontroller to control high-power devices that operate at AC 250V 10A or DC 30V 10A. This module is designed to be controlled by 5V logic signals (active low), making it compatible with popular microcontrollers such as Arduino, AVR, PIC, and ARM.

2. セットアップ手順
2.1 Connecting the Relay Module to a Microcontroller
- 電源接続: Connect the VCC pin of the relay module to the 5V output of your microcontroller (e.g., Arduino). Connect the GND pin of the relay module to the GND pin of your microcontroller.
- Control Signal Connection: Connect the IN1, IN2, IN3, and IN4 pins of the relay module to digital output pins on your microcontroller. These pins will control the individual relays.
- 負荷接続: For each relay, identify the Common (COM), Normally Open (NO), and Normally Closed (NC) terminals. Connect the device you wish to control to the appropriate terminals. For example, to switch a device on when the relay is activated, connect one side of the device to the power source and the other side to the COM terminal, then connect the NO terminal to the other side of the power source.

2.2 Using Dupont Wires
- Breadboard Connections: Use male-to-male wires to connect components to a breadboard.
- Microcontroller to Breadboard: Use male-to-female wires to connect microcontroller pins to components on a breadboard.
- Component to Component: Use female-to-female wires to connect two components with male headers.
- カスタム長さ: Wires can be pulled apart from the ribbon to create individual jumpers of desired lengths.
3. 操作手順
The ELEGOO 4-channel relay module operates with an active-low logic. This means that to activate a relay (close the circuit between COM and NO, and open between COM and NC), you must send a LOW signal (0V) to its corresponding IN pin from your microcontroller. To deactivate a relay (open the circuit between COM and NO, and close between COM and NC), send a HIGH signal (5V) to its IN pin.
- リレーのアクティベーション: Set the microcontroller pin connected to INx to LOW.
- Relay Deactivation: Set the microcontroller pin connected to INx to HIGH.
Ensure that the load connected to the relay does not exceed the maximum ratings of AC 250V 10A or DC 30V 10A.
4. メンテナンス
- ストレージ： Store the Dupont wires and relay module in a dry, dust-free environment to prevent corrosion and damage.
- 取り扱い： Handle electronic components with care. Avoid excessive force when inserting or removing wires and modules.
- クリーニング： 必要に応じて、柔らかく乾いた布でモジュールを優しく拭いてください。液体や研磨剤入りの洗剤の使用は避けてください。
- 検査： Periodically inspect wires for frayed insulation or bent pins. Replace damaged wires to ensure reliable connections.
5。 トラブルシューティング
- リレーが作動しない:
- Verify power connections (VCC to 5V, GND to GND).
- Ensure the control signal is active-low (sending LOW to IN pin to activate).
- Check if the microcontroller pin is correctly configured as an output.
- Inspect Dupont wire connections for looseness or damage.
- 断続的な接続:
- Ensure Dupont wire pins are straight and fully inserted into headers or breadboard holes.
- Check for bent or corroded pins on the relay module or microcontroller.
- デバイスが切り替わらない:
- Confirm the load is correctly wired to the COM and NO/NC terminals of the relay.
- Ensure the load's voltage and current requirements do not exceed the relay's maximum ratings (AC 250V 10A, DC 30V 10A).
- Test the load independently to ensure it is functional.
