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 Electronic Coin Toss circuit is an electronic version of the classic coin flip — often used to make quick decisions, settle disputes, or play games. It mimics the randomness of a real coin toss using digital logic or a microcontroller to generate a pseudo-random result and display it using LEDs or a text display (e.g., “Heads” or “Tails”).

A Battery High-Low Monitor is an electronic circuit or device that detects and indicates the voltage level of a battery — whether it’s too high (overcharged), normal, or too low (discharged). It helps protect batteries from overcharging or deep discharge, which can damage the battery or reduce its lifespan.
These monitors often use comparators, voltage dividers, LED indicators, or microcontrollers to track and display battery status in real time.

A Morse Code Generator is an electronic project designed to convert text input into Morse code signals using Arduino, a keypad, and a buzzer. Morse code is a method of encoding text characters as sequences of dots and dashes, widely used in communication systems, especially in emergency signaling and amateur radio. This project demonstrates signal encoding, microcontroller programming, and interactive electronics.
