Review on 4pcs MakerFocus ESP8266 ESP-01 WiFi Transceiver Receiver Module with 1MB SPI Flash, DC3.0-3.6V IoT WiFi Module Board, Compatible with Arduino by Frank Dubey

Doing small DIY projects I didn't realize I was missing something until I discovered them. If you want to control something wirelessly, such as For example, an LED, you typically buy a $20-$30 smart plug and a power supply to plug in, which will eventually control your LED or motor. With this module you can create a reliable and secure remote managed application in just a few hours. With Arduino Studio and other free software, you can quickly build all sorts of smart things and eventually connect them to any home automation hub (I have Wink), Alexa, or whatever. Another great advantage of these devices is that they don't need a specific manufacturer's cloud and app to work - just connect to your WiFi and get the job done.
