The tutorial details the operation and preparation of a device for communicating with a smartphone, allowing you to open a gate with a simple touch of the screen. For basic testing, you will need the following items:

1 ESP-01s Module (ESP-8266)
1 USB recorder with socket for ESP-01s

For residential installation, in addition to the items mentioned above, you will also need:

1 Relay module with socket for ESP-01s
Basic knowledge of residential electrical installations
To program the ESP-01s microcontroller, it is necessary to have basic to intermediate knowledge in the Arduino IDE, but implementation following the tutorial is simple. This is an initial basic version that demonstrates how the system works. In the future, we will launch a more robust application, full of functions to provide more practicality for technology enthusiasts. Follow the step by step and enjoy!
