JK11-12V 100S Adjustable Delay Relay Module with Infinite Cycle

Description

What is the JK11-12V 100S? The JK11-12V 100S is an adjustable infinite cycle delay relay module. It allows setting a configurable delay before activating a connected device via the relay. Features: Power Supply: 12V Integrated Relay Adjustable Infinite Cycle Adjustable Delay Use Cases This module is useful for projects requiring a delay between the activation of an electrical device and its operation. For example, it can be used to turn on lights after a certain period or control devices at regular intervals, creating smart lighting systems. It is compatible with Arduino and other microcontrollers. Tutorial: How to use JK11-12V 100S Delay Relay Module The JK11-12V 100S module is a useful component for projects that require a delay between the activation of an electrical device and its operation. This module is ideal for beginners and intermediate makers who want to add delay functionality to projects such as smart lights, aquarium pumps or any other device requiring a timer. What You Need Arduino Uno or similar Header connections USB cable Battery or external power supply Compatible relay Optional sensors Steps Connect the JK11-12V 100S module to the Arduino using header connections. Configure the module’s power supply (12V) through the power source or battery. Connect the relay to the JK11-12V 100S module following the instructions in the datasheet. Program the Arduino to send commands to the JK11-12V 100S module. Adjust the delay time using the module’s buttons. Test the module’s operation with a simple device like a light bulb. Verify if the JK11-12V 100S module responds correctly to the Arduino commands. Add sensors to conditionally activate the JK11-12V 100S module. Example Code void setup() { pinMode(2, OUTPUT); } void loop() { digitalWrite(2, HIGH); delay(1000); digitalWrite(2, LOW); delay(1000); } Mini Project Create a smart lighting system that turns on a light after 5 minutes from activation and turns it off after 5 minutes since the last movement detected. Common Mistakes Not correctly adjusting the delay time. Incorrectly connecting the relay. Improperly configuring power supply. Failing to test the module before integrating it into a larger project.
