Digital Clock Temperature Timer Relay Module / Cycle Delay / Timing / Self-Locking Switch Controller

Description

Temperature Timer Relay Digital Clock / Delay Cycle / Timing / Switch Controller

Tutorial: How to Use Digital Clock

The Digital Clock is a multifunction module ideal for projects requiring a digital clock, a timer, temperature control, and a relay. Suitable for beginners and intermediates, it allows you to monitor and control various aspects of your project.

What you need

• Arduino
• Connection Cable
• Resistor (10kΩ)
• Button
• 16×2 Display

Steps

1. 1. Connect the module to your Arduino using the indicated pins.
2. 2. Connect the relay to the output pin of the module.
3. 3. Connect the button to the input pin of the module.
4. 4. Connect the 16×2 display to the module.
5. 5. Add a 10kΩ resistor between the power pin and the display.
6. 6. Load the provided Arduino code.
7. 7. Configure the digital clock and timer using the dedicated pins.
8. 8. Test the module to ensure everything works correctly.

Example code

```
#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  lcd.begin(16, 2);
  lcd.print("Orario digitale");
}

void loop() {
  // Codice per il timer e il relè
}
```

Mini project

Create a simple 5-minute timer to turn on and off an LED. Start the countdown using the module and check the digital clock.

Common mistakes

• Forget to connect the relay to the output pin.
• Fail to configure the digital clock correctly.
• Leave the button unconnected.
• Do not use the resistor with the 16×2 display.

Recommended accessories

• LED
• 3V Battery
• Power Cable
• 16×2 Display

Frequently asked questions

How can I customize the digital clock?
Modify the pins used in the Arduino code to connect the 16×2 display differently.

Does the relay work with high currents?
Check the datasheet to confirm the maximum current supported.

Can I use a different display?
Yes, but verify that the display supports I2C or SPI communication.

Does the module support multiple timers?
Check the datasheet to confirm the timer management capability.
