Each LED is connected to one of the Arduino's digital output pins through a 220Ω resistor. A push button is connected to each input pin and uses the internal pull-up resistor feature of the Arduino.

⚠️ Important: Connect the P10 module's power terminals to a separate 5V, 3A SMPS power supply, not to Arduino's power pins. Arduino UNO P10 LED Module +5V ────────────────────── VCC (via SMPS) GND ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...
