nodemcu作为client，连接程序，远程点亮小灯

cl = net.createConnection(net.TCP, 0)		--创建一个tcp
cl:connect(19660, "192.168.1.4")			--19660为端口号
gpio.write(0, gpio.HIGH)					--将0脚和1脚都置为高电位，小灯都熄灭
gpio.write(1, gpio.HIGH)
cl:on("receive", function(sck, c) print(c)if(c=='0')then							--如果接收到tcp数据为0，0灯点亮，1灯熄灭gpio.write(0, gpio.HIGH)gpio.write(1, gpio.LOW)else gpio.write(0, gpio.LOW)gpio.write(1, gpio.HIGH)endend)
cl:on("disconnection", function(sck, c) print("disconnection!") end)
