Robot Sunflower Follows the Sun
Originally published on hackaday.com by Al Williams on 3 November 2023
The article highlights the creation of a plastic sunflower that mimics the sun-tracking behavior of real sunflowers. While it may not be classified as a full-fledged robot, the project uses an Arduino, a light sensor, and a servo motor to achieve its sun-tracking capability. The simplicity of the electronics makes it a great project for educational purposes, potentially engaging students in both electronics and nature-inspired engineering. The use of light-dependent resistors enables analog readings to determine the sensor receiving the most light.
The sunflower project employs a pair of light sensors, adding a layer of redundancy to ensure precise tracking. The sensors are not binary on-off devices but are light-dependent resistors, allowing for nuanced analog measurements. While it’s possible to implement the sunflower’s behavior without an Arduino, the versatility and affordability of microcontrollers make them a suitable choice for such projects. This whimsical creation showcases a fusion of technology and artistry, providing an interesting and accessible entry point for educational activities.
