Connect the ESP32 to the relay module and the light source as described in the Wiring section. Upload the Arduino code to the ESP32 using the Arduino IDE. Observe the light source as it displays the ...

you need: esp32/esp8266 (at moment ESP32 S2 is used!), a relay module (2 relay module at moment), a (110/220V) micro powersupply, a case and 2 push buttons (3 push button at moment) you need connect ...

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 are using the transistor ...

Now take the two relay modules and connect the Vcc and ground of the modules to the Vin and ground of the ESP32 microcontroller board in parallel. Connect the in-pin of the relay modules to the pin34 ...

Waveshare ESP32-S3-Relay-6CH is a 6-channel WiFi and Bluetooth relay module based on Espressif Systems ESP32-S3 wireless microcontroller that also supports RS485 control and comes with headers taking ...

Materials Required. ESP32 Development Board; AC Load (Lamp) Relay Module . Hardware. The hardware for this ESP32 BLE Client project is pretty plain since most of the magic happens inside the code. The ...

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 ...
