JK11-12V 1S-15mins Adjustable Delay Relay Module with Infinite Cycle

Description

What is the JK11-12V? The JK11-12V is a multifunction delay relay module for electronic projects. This module allows you to adjust the activation delay of the relay from 1 second to 15 minutes. Features Adjustable Delay Relay Module JK11-12V Power Supply: 12V Adjustable delay from 1 second to 15 minutes Compatible with Arduino and other microcontrollers Multifunction relay module Adjustable infinite cycle What is it for? This module is ideal for creating custom timers, presence counters, and automatic lighting systems. It can be used in DIY projects such as home automation and other electronic control systems. It is compatible with Arduino and other microcontrollers. Tutorial: How to use the JK11-12V Delay Module The JK11-12V delay module is an electronic component useful for controlling the activation time of a relay. Ideal for DIY projects like home automation, presence counters or custom timers. What you need Arduino Uno Power connections Control connections Steps Connect the JK11-12V module to 12V power Supply Connect the JK11-12V module to an Arduino control pin Set the delay using the adjustment knob Verify relay function with a connected LED Test infinite cycle of the relay Example code void setup() { pinMode(2, OUTPUT); } void loop() { digitalWrite(2, HIGH); delay(10000); digitalWrite(2, LOW); delay(10000); } Mini-project Create an automatic lighting system that turns on and off a light after a settable delay. Common mistakes Setting the delay too low Connecting the module to voltages other than 12V Not verifying relay function before using the final project Recommended accessories Arduino Uno LED Resistor Connection cable Frequently Asked Questions How do you adjust the delay of the module? Use the adjustment knob on the JK11-12V module to set the desired delay. Can it be used with voltages lower than 12V? Check the datasheet for compatibility with voltages other than 12V.
