AURDINO :- The Arduino microcontroller has communication ports and input / output ports. with which we can connect different types of peripherals on the board. DC MOTORS:- When kept in a magnetic field, a current-carrying conductor gains torque and develops a tendency to move. |
scarecrow, device posted on cultivated ground to deter birds or other animals from eating or otherwise disturbing seeds, shoots, and fruit; its name derives from its use against the crow. |

OPTICAL FIBER:-Optical fiber uses the optical principle of "total internal reflection" to capture the light transmitted in an optical fiber and confine the light to the core of the fiber. SPANNER:- A spanner works by gripping a fastener and twisting it clockwise or anticlockwise to tighten or loosen it. |

SOLAR PANELS:-When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow. GEARS:-Gears use the principle of mechanical advantage, which is the ratio of output force to input force in a system. |
The common form of a scarecrow is a humanoid figure dressed in old clothes and placed in open fields to discourage birds such as crows or sparrows from disturbing and feeding on recently cast seed and growing crops. |

Beeper:-Buzzer is an electrical device that is used to get a buzzing or beeping sound when a potential difference is created or voltage is applied. SPANNER:- A spanner works by gripping a fastener and twisting it clockwise or anticlockwise to tighten or loosen it. |
Humans have taken the (scarecrow) as a protector for these crops from the birds. |

REGULATORY CIRCUIT:- A voltage regulator is a circuit that creates and maintains a fixed output voltage, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other electrical components. DC MOTORS:- When kept in a magnetic field, a current-carrying conductor gains torque and develops a tendency to move. |
A Smart scarecrow is used to scare the birds and to the animals to save the crop in the fields. A farmer put the smart scarecrow within the middle of the sector to save lots of his crop from the birds and animals. |

PROXIMITY SENSOR:-Inductive Proximity Sensors detect magnetic loss due to eddy currents that are generated on a conductive surface by an external magnetic field. An AC magnetic field is generated on the detection coil and changes in the impedance due to eddy currents generated on a metallic object are detected. SPANNER:- A spanner works by gripping a fastener and twisting it clockwise or anticlockwise to tighten or loosen it. |

LED:-LEDs work on the principle of Electroluminescence. On passing a current through the diode, minority charge carriers and majority charge carriers recombine at the junction. On recombination, energy is released in the form of photons. DC MOTORS:- When kept in a magnetic field, a current-carrying conductor gains torque and develops a tendency to move. |
