Aim
The aim of the project is to Construct a decorative sunflower with petals that open and close based on the sunlight, using a light sensor and a servo motor.
Problem statement
The system should incorporate solar panels with dynamic tracking capabilities, allowing them to follow the sun’s movement throughout the day. Address challenges such as precision in solar tracking mechanisms, energy efficiency, and durability in varying weather conditions. Develop a solar-powered Sunflower solution that offers an innovative approach to solar energy harvesting, suitable for both residential and commercial applications, contributing to increased efficiency in solar power generation.
Material used
Input: 2 Light Sensor
Brain: TinkerSpace Brain Board
Output: Servo Motor
Battery: 5V Lithium-ion rechargeable battery
Component description
2 Light sensor
Servo Motor
Servo motor is used to track the movement of the sun and rotate in a same direction where sun is detected
TinkerSpace Brain Board
TinkerSpace board acts as brain of this project, its function is to monitor Light Sensors and control LED LAMP, Servo Motor.
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case 1: When the light is detected in left, left light sensor turns ON and sends the signal to the brain board. The brain board oscilates servo motor to 0Degree .
Case 2: When the light is detected in right, right light sensor turns ON and sends the signal to the brain board. The brain board oscilates servo motor to 180Degree
Case 3: When the light is detected in both sides, both light sensor turns ON and sends the signal to the brain board. The brain board oscilates servo motor to 90Degree.
Case 4: When no light is detected in both sides, both light sensor turns OFF and sends the signal to the brain board. The brain board oscilates servo motor to 90Degree .
Circuit Design (DesignSpace)
Step 1: Connect 2 LIGHT SENSOR to input 1 and input 2
Step 2: Connect Servo Motor to output 1
Step 3: Connect supply and test project.
