The main component is ESP8266 board which allow to run script in LUA language. This ESP8266 board is connected with relaen-USTelligent Community 12https://community.element14.com/challenges-projects/project14/portable-electronics-kit/b/blog/posts/control-an-relay-from-web-server-using-nodemcuTue, 06 Mar 2018 01:12:46 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:83398e5d-31bf-473b-81e3-65242c85ed6brcaste531<p>The connection of 1N4148 diode es wrong.
