The controller also features a 2.33-inch touchscreen display, a 10A relay, a 12V to 24V DC screw terminal for power ... and external antenna LILYGO provides Arduino code samples for all features, ...

We started off talking about the early days of the Arduino revolution. Sure, folks have been building hobby projects with microcontrollers built in before Arduino, but the combination of a ...

The PCB within holds some alarming surprises, like the minimal physical isolation between the mains part of the circuit and the low-voltage section, but the real treat is the Schottky diode that ...

A relay module is also connected to the ESP32’s GPIO 13, providing the ability to control external devices like additional lighting or security systems using gesture commands. The WS2812 LED strip is ...

it features a 1.28” capacitive touch display (240×240), and a UI designed with LVGL/Squareline and the Arduino V2.3.4 IDE. The device relies on a BT139 Triac and a zero-cross detection circuit for ...

This project is an automated garden watering system using an ESP32, relay module, solenoid valve, and a Python backend with MQTT. The system allows remote control of a solenoid valve via MQTT messages ...
