2V Delay Trigger Normally Open Relay / Time Circuit Module / Vibration Alarm Module

Description

What is the 2V Delay Relay ARD0011776? The 2V Delay Relay ARD0011776 is an electronic module that allows a circuit to be activated after a certain delay period. It’s useful for creating security alarms, timers or control systems with programmable response times.

Features:
– Supply Voltage: 2V
– Relay Type: Normally Open
– SKU: ARD0011776
– Price: £3.25

How to Use the Delay Relay Module? The delay relay is ideal for controlling electrical devices with programmable delays, suitable for beginner and intermediate makers.

Steps:
1. Connect the relay to an Arduino using the following pins: VCC to 5V, GND to GND, and control pin (COM) to a digital pin.
2. Connect a 1kΩ resistor between the VCC pin and the COM pin.
3. Connect the load to be controlled between the NO pin and GND.
4. Upload source code to your Arduino.
5. Configure desired delay from datasheet.
6. Verify power supply specifications on datasheet.
7. Test relay to ensure proper functionality.
8. Check operation specifications on datasheet.

Example Code:
“`
int relayPin = 2;
void setup() {
pinMode(relayPin, OUTPUT);
}
void loop() {
digitalWrite(relayPin, HIGH);
delay(5000); // Delay of 5 seconds
digitalWrite(relayPin, LOW);
}“`

Mini Project: Create a security alarm that activates a light after 5 seconds from activation.
Common Mistakes:
– Do not use VCC pin as control pin.
– Do not connect power directly to load without resistor.
– Don’t forget to set the pin as OUTPUT.
– Avoid using too long delays which may damage Arduino.

Recommended Accessories:
– Arduino UNO
– LED Light
– Power Cable
– 1kΩ Resistor
