This DIY HF antenna preselector drastically improves the listening experience on your shortwave radio, especially with a long wire antenna.

In this Visuino project, you will learn how to use the ESP32-C3 LCD kit to control an RGB LED’s brightness with a rotary encoder. Turning the encoder adjusts the brightness in steps from 0 to 1 with 0.1 increments, and the current brightness level is shown directly on the LCD display. Pressing the encoder’s button instantly sets a random LED color, making the project both fun and interactive. This tutorial is perfect for learning how to: Configure and Use the rotary encoder on ESP32-C3 Display live brightness values on the LCD screen Randomize LED colors with a simple button press Use Visuino Visual Programming to quickly design interactive IoT projects Bring your ESP32-C3 LCD kit to life with this engaging RGB LED brightness controller!

Create a secure Arduino RFID Door Lock using Visual Programming in Visuino! Learn how to connect the MFRC522 RFID module, verify card IDs, and control a magnetic solenoid lock. When a valid RFID card is detected, the door unlocks and a green LED confirms access. Swipe again to lock the door. No coding needed — perfect for beginners and smart home security projects.

In this step-by-step tutorial, you’ll discover how to create sequences that control your actuator with precise timing (in milliseconds or even microseconds).

In this Visual Programming (Visuino) tutorial, we’ll use a High Brightness Lighting LED Module and a Rotary Encoder to control LED brightness and blinking modes.
