The ESP32 Web Relay is a simple yet effective device for controlling a single relay switch via a web interface. It's built using an ESP32 microcontroller and allows for easy network-based control and ...

Transistor as a switch. In the above figure, connect the Vin port to the pins of the ESP32, connect the port Vcc to the external 5V supply and connect Vo to the relay module. The main reason that we ...

Note that like many of LilyGo boards, T-Relay-8 does not come with an on-board USB-to-TTL chip, and instead, users would need to connect the T-U2T dongle based on the CH9102 chip to program the ESP32 ...

Code Explanation. We explained Face Recognition with ESP32 in the previous article; here we will modify the same code to control a solenoid door lock. The complete code is divided into four parts. One ...
