Arduino Controlled Relay
Using a relay allows an Arduino microcontroller to power a high voltage object. This kit contains what you need to build a relay that can be used to control a grow light or a sprinkler in an aeroponics system. Use this system to replace the timer included in the SpaceLite (Plant Light) Kit and the Classroom Aquaponics Kit. Order this kit online from agclassroomstore.com.
