The Shield features four relays, each relay provides 2 pole changeover contacts (NO and NC); in order to increase the current limit of each output the 2 changeover contacts have been put in parallel. Four LEDs indicate the on\/off state of each relay.\u003c\/p\u003e\n\n\u003ch3\u003eGetting Started\u003c\/h3\u003e\n\n\u003cp\u003eYou can find in the Getting Started section all the information you need to configure your board, use the Arduino Software (IDE), and start tinker with coding and electronics..\u003c\/p\u003e\n\n\u003ch3\u003eNeed Help?\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eOn the Software on the Arduino Forum\n\u003c\/li\u003e\n\t\u003cli\u003eOn Projects on the Arduino Forum\n\u003c\/li\u003e\n\t\u003cli\u003eOn the Product itself through our Customer Support\n\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Arduino","offers":[{"title":"Default Title","offer_id":39501293092898,"sku":"A000110","price":0.0,"currency_code":"VND","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0289\/0180\/2018\/files\/A000110_02.front.jpg?v=1790049631","url":"https:\/\/chanhvinh.com\/products\/arduino-4-relays-shield","provider":"CÔNG TY TNHH THƯƠNG MẠI DỊCH VỤ CHÁNH VINH (Vật tư công nghiệp)","version":"1.0","type":"link"}
