Blynk IoT (Blynk 2.0) App w/Arduino Uno R3, ESP8266 ESP-01 Module, Blynk Cloud & 4 x LED [TUTORIAL]

Note (18/6/2022): Seen at 4:33, the AT command for checking UART/Baud Rate on your ESP8266 ESP-01 only appears to work if the module is flashed with SDK 2.x or above. In other words, if your module has the older 1.3.0 SDK the 'AT+UART?' command will simply give an 'ERROR' message on the serial monitor. However, you can still set the UART/Baud Rate using 'AT+UART=38400,8,1,0,1' regardless of which SDK your module has. If you're not sure which SDK version your ESP8266 ESP-01 module has, simply type 'AT+GMR' in the Serial Monitor and it will tell you. Note (8/5/2022): We are using Blynk IoT / 2.0 and NOT the deprecated Blynk Legacy. The ESP8266 ESP-01 module should be set to 38400,8,1,0,1 (from the default 115200,8,1,0,1) for UART/Baud Rate.
