Numato Lab’s 4 Channel Relay breakout module is a smart choice for controlling higher current loads from your microcontroller development board, PC parallel port, or your favorite Arduino. This board has four on-board relays which can switch up to 10A. All relay terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The relays are driven by popular Darlington array ULN2003. The relay coil is rated for 12VDC.
Features
- Very compact and easy to wire up
- 1.6mm FR4 PCB with black solder mask and white silkscreen
- Connects directly to TTL devices (Microcontrollers, Arduino, etc..)
- Four Relays with one three-pin screw terminals for easy connectivity
Applications
- Home Automation
- Industrial Automation
- Lighting Control
- Garden Equipment Control
- Test Fixtures
- DIY and Hobby

An Automatic Room Cooling is an electronic system designed to maintain a comfortable room temperature automatically. It uses a DHT11 temperature sensor to monitor the room, a DC fan for cooling, an LCD to display real-time data, and a buzzer to provide alerts. The system activates the fan automatically when the room temperature exceeds a set threshold, making it an efficient solution for homes, laboratories, and small offices.

A Flip-Flop LED Flasher is a simple electronic circuit that alternately turns two LEDs on and off in a continuous loop, creating a blinking or “flashing” effect. It’s commonly built using transistors, resistors, capacitors, and LEDs, forming an astable multivibrator — a basic circuit that oscillates between two states without any external triggering.
It’s often used for decoration, indicators, or learning basic electronics.

A Touch ON/OFF Switch is an electronic circuit that allows a device to be turned on or off by simply touching a sensor pad or wire, instead of using a mechanical switch. It works by detecting a small electrical signal from the human body (capacitive or resistive touch) and using that to toggle the output state.
These switches are commonly used in modern electronics, home automation, and DIY projects due to their durability, aesthetic appeal, and user-friendly operation.

A Digital Lock System is an electronic security project designed to control access using a password entered via a keypad. It utilizes an Arduino, keypad, LCD, servo motor, and buzzer to provide a safe, automated locking mechanism. When the correct password is entered, the lock opens; if the wrong password is entered, an alert is triggered. This project is widely used in home security, lockers, safes, and access-controlled systems.
