250VAC 30VDC Arduino 2 Relay Module Expansion Board , Control Panel
In doing interactive projects using Arduino, a lot of high current
or high voltage devices usually can not be directly used the
Arduino digital IO port control
(Such as solenoid valves, lamps, motors, etc.), then you can
consider using the relay programs to address.
Arduino Relay Shield is the use of high-quality relay Songle
provides two inputs and outputs can be connected up to the exchange
Or 24V/10A DC device, thus can be used to control the lamps, motors
and other devices.
The modular design makes it easy to connect with Arduino expansion
boards. Relay output state by a light-emitting diode that
facilitate practical use.
