The ESP8266 WiFi module was presented at its introduction as a TTL "Serial to Internet" module. Handy to connect Arduino boards to the internet. It soon turned out that this ESP-01S module and its number of GPIO pins, outwardly carried, bigger brothers (ESP-7, ESP-12, NodeMCU etc.) can do much more than just supplement an Arduino. The processor is many times more powerful than the Atmel processor of the Arduino Uno and the memory is many times larger (1 MB!). The modules can be used as fully-fledged independent micro processors, with WiFi connectivity! "

Point of attention. There is NO RED POWER LED on this print. The only LED on it is a BLUE LED. This is not connected to GPIO1, but to GPIO2. Adjust the Arduino-Compiler option Buildin Led: "1" to Buildin Led: "2"
