Numato 2 Channel Relay breakout module is a smart choice for controlling higher current loads from your microcontroller development board or a PC parallel port. This board has two 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..)
- Two 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 XOR (Exclusive OR) gate is a digital logic gate that outputs true (1) only when the number of true inputs is odd. For two inputs, the output is high when the inputs are different. XOR gates can be constructed using basic logic gates or directly with transistors (BJT or MOSFET). Using transistors, we can design compact, efficient circuits for custom digital logic applications.

A Reaction Time Game is an interactive electronic project designed to measure a user’s response speed. Using an Arduino, keypad, buzzer, and LCD, the system tests how quickly a player can respond to a visual or auditory signal. This project is widely used in educational setups, gaming, and psychology experiments to study reflexes and reaction times.

A Traffic Light Signal is an electronic project designed to manage vehicle and pedestrian traffic at intersections. Using Arduino, LEDs (Red, Yellow, Green), and an LCD, the system simulates real-world traffic light behavior, displaying signal changes with appropriate timing. This project demonstrates traffic management, embedded system programming, and microcontroller-based automation.
