Relay

The Relay Shield provides four high quality relay that can control high current loads to Arduino / Seeeduino boards. It also provides NO (Normally Open) / NC (Normally Closed) interface. It could be a nice solution for controlling devices that could not be directly controlled by Arduino’s Digital I/Os. Standardized shield form factor enables smooth….

Enables the Arduino board to turn on/off devices such as TVs, audio systems, lights and other electrical devices up to 10A/220VAC or 10A/30VDC. Suitable for home/office automation, or controlling other installed equipment.

A multi-purpose shield designed for classroom use and for quick prototyping of a wide variety of projects. Provides a significant prototyping area for custom projects, and a number of optional sub-systems that can be included or excluded as required: 20×4 LCD. XBee module. Button inputs. Analog inputs. Temperature sensor (DS18B20 on 1-wire bus) Light sensor…..

6 onboard relays, 6 digital inputs and 6 analog inputs. The digital inputs and relay outputs are equipped with an LED that indicates the status.

Drive up to 8 relays from your Arduino using just 2 I/O pins. Communicates with your Arduino using I2C, so you can stack several shields together to drive 16, 24, or more outputs. I2C connections are linked by default to Arduino pins A4 and A5, but can be switched to use the R3 headers using….

This Relay Shield v2.0 from Evil Mad Scientist is a simple Arduino add-on that gives your Arduino the ability to control a single electromechanical relay for switching loads of up to 24VDC or 40VAC. Each Relay Shield comes equipped with a single pole – double throw (SPDT) sealed relay which can handle a current load….

10 Amp power relay.

Combination of relay output and a 5-digit 7-segment display. Features: 5 RED 7 segment LED displays to display data up to 99999. Uses simple SPI interface for connecting with Arduino. Can be cascaded. Relay connected to pin D2 operates at 5VDC capable of switching up to 7A/250VAC. Note: this shield has female connectors on the….
