Look Grove LED node setting. Check port number in node setting and connecting port number.

Generally the sample flow default port setting is D18. If your setting port is defferent from sample flow D18. Fit port your connecting port and node setting port number.

Click Node-RED inject nodes written 1 and 0. When inject nodes as 1, Grove LED will turn on. When inject nodes as 0, it will turn off.
