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 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.

An Electronic Dice is a digital version of a traditional dice, which generates a random number (1 to 6) and displays it using LEDs or a 7-segment display. It uses components like a 555 timer, counter IC (like CD4017), or microcontrollers such as Arduino to simulate dice rolls electronically.

The Conveyor Belt Object Counter using LDR and 7-Segment Display with the 8051 microcontroller is designed to count objects passing in front of an LDR (Light Dependent Resistor) sensor. The system works by detecting light interruptions when an object crosses the sensor, causing a change in the LDR’s resistance. The microcontroller processes this change and increments an object count. The count is then displayed on a 7-segment display.
