Internet controlled LED using Arduino and ESP8266 | Part 1
Internet controlled LED using Arduino and ESP8266 | Part 1 last week I've been into some IoT projects and thought of sharing them with you. Well this one contains very basic stuff about controlling hardware through a web server. I'll start from the beginning and continue to some real home automation projects step by step. Stuff we are gonna need. Arduino development board ESP 8266 Module USB to TTL converter. 3.7v Lithium polymer Battery. A web server ( 000webhosting is a good free service) Jumper Wires Note: If you are not using a battery, use a step down regulator. You can find one here .
