Numato Lab’s 8 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 eight 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 ULN2803. The relay coil is rated for 12VDC.
Features
- Very compact and easy to wire up
- 1.6mm FR4 PCB with Green solder mask and white silkscreen
- Connects directly to TTL devices (Microcontrollers, Arduino, etc.)
- Eight Relays with three-pin screw terminals for easy connectivity
Applications
- Home Automation
- Industrial Automation
- Lighting Control
- Garden Equipment Control
- Test Fixtures
- DIY and Hobby

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.

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.
