Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that’s just out of the box)! The ESP8266 module is an extremely cost effective board with a huge, and ever growing, community. It is designed for smart home Automation, Internet of thing and other DIY project. After opening the Arduino IDE, head over to preferences. You can check the specs of the relay here. edu and/or orally in person at the meeting. On-board SPDT relays are ideally suited for control of low to medium power loads up to an absolute maximum 10 Amps at 240VAC depending on relay chosen during purchase. Is is attached to a string of Neopixels (WS2812 leds) of which you can control loads with just 1 pin of your controller. Until now I. Those were originally used to provide low cost WiFi connectivity to a master MCU, such as an Arduino compatible board.
