Arduino

Arduino is a family of inexpensive microcontroller boards that are widely used for custom electronics projects. They are well suited for controlling relays, motors, servos, sensors, LEDs, and other hardware commonly found in animated holiday displays.

Although many modern Christmas displays use ESP8266 or ESP32 controllers because they include built-in Wi-Fi, Arduino boards remain an excellent choice for stand-alone prop control, motion systems, and learning embedded programming.

Common Uses

• Relay control
• Servo control
• Stepper motors
