🔧 Introduction to Flood Alarm Project

The video begins with an introduction to a DIY flood alarm project by School Center Sekolah Pembangunan Jaya, featuring Mr. SQ. The main objective of the project is to create a simple flood alarm to detect rising water levels early. The necessary materials include a single battery, wire, scissors, a stick, string, a small and large diameter straw, aluminum foil, and a marker. The first step involves creating a box with dimensions of 3x4 cm. After making the box, specific points are marked at a distance of four centimeters apart. The video then proceeds to demonstrate how to make holes in the box using a cutter, emphasizing the need for adult supervision due to the potential danger of the tool.

📏 Crafting the Alarm Structure

The second paragraph details the process of cutting a large diameter straw to a length of 10 cm and a smaller one to 16 cm. The straws are then prepared to be inserted into the holes made in the box. The video demonstrates how to stand the straws upright using tape and a marker to ensure they are straight. Next, the largest straw is inserted into the hole, leaving about 1 cm of the straw exposed above the box. The edges are then sealed with tape. The video also shows how to attach a piece of styrofoam and aluminum foil to the structure, securing them with tape. The process is carefully explained, with reminders to wait for the tape to dry before proceeding.

🔌 Wiring the Flood Alarm

Paragraph three focuses on the electrical assembly of the flood alarm. It begins with the preparation of the electrical components, including connecting a black wire from the battery to the base and a red wire to the floor. The video instructs viewers to connect the red wire to the engineer, ensuring a complete circuit. The assembly is then tested by attaching the battery, and the video demonstrates how to attach the battery and wires to the styrofoam using tape. The process includes attaching the black and red wires to the bottom and top of the styrofoam, respectively, and securing them with tape. The video concludes with a test to ensure the alarm is functional and ready for use.

💧 Testing the Flood Alarm

The final paragraph demonstrates the testing of the flood alarm. It explains that the alarm works by detecting the rise of water levels. When the water level reaches the top of the styrofoam, the small straw will touch the longer straw, triggering the buzzer to sound, indicating a flood. The video shows a simulation of a flood by pouring water into the holes of the alarm. As the water level rises, the alarm is triggered, and the buzzer sounds, signaling that the alarm is working effectively. The video concludes with a reminder to always be prepared and to seek help when needed, and it invites viewers to join more experiments in future School Center videos.
