Solar panel, battery, charge controller |
Motor stand, rotating pole, gears |
Law of Conservation of Energy: Solar energy is converted to electrical energy and stored in a battery to power the model |
The energy from sunlight is harvested using a solar panel, stored in a battery, and then used to power both the rotating panel and the moving gondola. |

Light-dependent resistor (LDR), Arduino |
DC geared motor, mounting gear mechanism |
Solar Panel Rotation: Based on LDR feedback, the motor rotates the panel to face the sun for maximum efficiency (solar tracking system). |
LDRs detect the direction of maximum sunlight. Arduino compares the values and triggers the motor to rotate the solar panel for optimal exposure. |

Esp32, motor driver, DC motor |
Spur gears, shafts |
Gear Mechanism: Gears convert the rotary motion from the motor into controlled motion for the panel or cable car using mechanical advantage. |
DC motor controlled by esp32 rotates the gears, which convert high-speed rotation to controlled and directional motion in the panel and gondola system. |

Battery (charged by solar panel), ESP32, motor driver |
Pulley cable system, tower frame, gondola car |
Movement of Gondola: DC motor turns the pulley via ESP32 control to move the gondola between two points, demonstrating electric motion control. |
The gondola moves along a wire using the energy stored in the battery, powered and automated by ESP32. |
