Tutorial: How to use Arduino HTV6-DC5V-SH Relay

The Arduino HTV6-DC5V-SH relay is ideal for controlling 5V electrical devices. It is useful for beginner and intermediate makers who want to automate circuits.

What you need

• Arduino UNO or compatible
• 5V power supply cable
• 1kΩ resistor
• Connection cable

Steps

1. 1. Install the relay on the circuit, ensuring that the metal part does not touch other components.
2. 2. Connect Arduino pin 7 to relay pin 1 (Common).
3. 3. Connect Arduino pin 8 to relay pin 2 (NO).
4. 4. Connect Arduino pin 9 to relay pin 3 (NC).
5. 5. Connect a 1kΩ resistor between relay pin 1 (Common) and ground.
6. 6. Connect a device to be controlled between relay pin 2 (NO) and relay pin 3 (NC).
7. 7. Connect ground to the relay.
8. 8. Load the source code onto the Arduino.

Example code

```void setup() { pinMode(7, OUTPUT);}void loop() { digitalWrite(7, HIGH); delay(2000); digitalWrite(7, LOW); delay(2000);}```

Mini project

Create an automatic lighting system. Connect an LED to relay pin 2 (NO) and 3 (NC), controlled by Arduino pin 7.

Common mistakes

• Do not check if the relay is properly installed.
• Do not use a compatible Arduino.
• Connect the relay directly to power supply without resistor.
• Neglect the order of connection.

Recommended accessories

• Arduino UNO
• LED
• 1kΩ resistor
• 5V power cable

Frequently asked questions

Can I use an Arduino Uno or compatible?
Yes, the Arduino UNO is compatible. Check the datasheet for other models.

Which resistor to use?
Use a 1kΩ resistor between pin 1 of the relay (Common) and ground.

Can I connect an electrical device directly?
No, connect the device between pins 2 (NO) and 3 (NC) of the relay.
