Abstract

Park is a green open space widely used by the community to carry out various activities ranging from recreation, playing, sports, and other passive activities. Current weather conditions are often uncertain. This makes people inconvenient when it rains suddenly, especially when outdoors such as in parks. Because if they don't immediately take shelter when it rains, it can make the body sick, besides that, rainwater can damage the non-waterproof gadgets they carry. In other conditions, when the weather is bright, and the sun is shining hot, it can make people feel hot and lazy to do outdoor activities in the park. Therefore, an automatic umbrella tool was made that functions as a shelter in the garden. In this tool, there is a light sensor module and also a rain sensor, which is controlled with the Arduino Uno microcontroller as an input data processor and an L298N motor driver, which functions to regulate the speed and direction of the DC motor rotation (to the right and left) as an umbrella drive. When the motor rotates to the right, the umbrella will open, while when the motor rotates to the left, the umbrella will close again.

Abstract

Cattle cage is a term that refers to a structure used to house farm animals or animal homes. The structure might be in the form of a container, a building, or something else entirely, depending on the type of animal being farmed. Because most cattle shed doors are slotted or padlocked, there is a high rate of theft from irresponsible individuals seeking to take livestock without permission. The primary objective of this research is to devise a security system capable of keeping cattle pens secure and free of thieves or burglars that cause livestock loss. The author chooses the Atmega 328 microcontroller because it features a Harvard architecture that separates program code and data memory to maximize work and parallelism. Additionally, this circuit may be connected to an Arduino Uno to create a variety of electronic circuits ranging from simple to complicated. LED control, helicopter control, servo drive control, and robot control can all be implemented by adding specific components. Thus, a prototype was created for an automatic door safety system that employs an infrared sensor to detect the presence of animals and automatically opens the entrance, locking it with a password and ringing a buzzer in front of the farmer's house if the password is incorrect. This tool was created to help minimize cattle losses due to theft.
