"Sun-Tracking Robot Sunflower Harnesses Solar Power"
Originally Published 2 years ago — by Hackaday

A plastic sunflower, equipped with an Arduino, light sensors, and a servo motor, mimics the movement of a real sunflower by tracking the sun. This simple yet whimsical project could be a great school project to engage students in electronics and programming. The use of light-dependent resistors allows for analog readings to determine the sensor receiving the most light. While alternative circuitry could achieve the same effect, the versatility and affordability of microcontrollers make them a popular choice.
