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 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.

This project involves controlling a DC motor’s direction using an 8051 microcontroller, with a buzzer and LED indicating the motor’s rotation state. When the DC motor rotates forward, the microcontroller keeps the buzzer and LED off. However, when the motor is rotated in reverse, the microcontroller triggers both the buzzer and LED to turn on as a visual and audible indication of the motor’s reverse rotation

A Security Alarm Circuit using the LM358 IC is a simple yet effective system designed to trigger an alarm when unauthorized access or movement is detected. The LM358, a dual operational amplifier (Op-Amp), is used as a comparator to detect voltage changes from sensors like LDRs, IR sensors, or switches, and then activate a buzzer or relay.

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.
