Fan Blade (Pack of 20)

Description

A small, durable plastic fan blade engineered to attach directly to the rotating shaft of standard 3V-6V hobby direct current (DC) motors. In an educational STEM environment, it serves as a highly visual and engaging accessory used to demonstrate the conversion of electrical energy into kinetic energy and airflow. It is frequently utilised in hands-on projects such as building miniature desktop fans, constructing simple hovercraft models, or exploring basic aerodynamics. When paired with a DC motor controlled by development platforms like the Arduino UNO or Magic Board, students can write code to adjust the fan’s rotational speed using Pulse Width Modulation (PWM) or trigger its activation based on environmental inputs, such as temperature thresholds detected by a DHT-11 sensor.
