Numato Lab’s 32 Channel Relay Controller Board is a smart choice for controlling higher current loads from your microcontroller development board or a PC parallel port. This board has thirty-two onboard relays which can switch up to 7A. 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 ULN2803. The relay coil is rated for 12VDC.
Features
- 32 onboard SPDT Relays.
- 7A Maximum Switching Current.
- ULN2803 Relay Driver.
- Very compact and easy to wire up
- Connects directly to TTL devices (Microcontrollers, Arduino, etc..).
Applications
- Home Automation
- Industrial Automation
- Lighting Control
- Garden Equipment Control
- Test Fixtures
- DIY and Hobby

A Visitor Counter automatically counts the number of people entering or leaving a room using an IR sensor. The count is displayed on a 16×2 LCD, and a buzzer can alert when a specific limit is reached. This project is widely used in shops, libraries, offices, and events to monitor occupancy. It demonstrates sensor interfacing, counting logic, and real-time display using Arduino.

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.
