Introduction
In this tutorial, we will show how to make a powerful alarm using a DC motor for your science project in easy-to-implement steps. The DC motor is a device that helps to convert direct current into mechanical energy.
Supplies
To make this alarm, we will need the following tools and materials.
Tools
- Dc motor
- Battery
- Wire
- Screw
- Hot glue gun
Material
- Cardboard box
- White or Color chart paper
- Steel vessels glass
Steps To Make A Powerful Alarm Using A DC Motor
Step 1: First, take a screw and connect it with a wire.
Step 2: Now take the DC motor and with the help of the coupling screw, connect the wire and screw with it.
Step 3: Now stick this DC motor in a bottle cap.
Step 4: Now stick a steel vessel and DC motor, and batteries in cardboard.
Step 5: Now connect the battery wires (red with red and left black one) and connect them with the DC motor using the soldering iron.
Step 6: Now, take an old syringe and cut it into two parts.
Step 7: Now connect a screw with the black wire and put it in one part of the syringe.
Step 8: Now, stick both the syringe with a plastic straw and stick them in cardboard.
Step 9: Now connect the battery’s wire with another screw and put it in the upper part of the syringe.
Step 10: Now, as soon the screw touches each other, the screw starts beating the vessel, and a powerful working alarm is ready!
Students can add a piece of card between the screws to turn on and off the alarm, as add the card, the alarm stops, and however remove the card between screws, the alarm starts ringing! Now the powerful alarm science model is ready for science exhibition.
Recommendation
By doing this project, students understand the concept of working DC motors and how the alarm works.
Things To Remember
- Working slowly and carefully during cutover.
- To protect your work surface, use a self-healing mat.
- Learn all you can about the materials and techniques you’re using.
- Work carefully during wire attachment.
- The battery will be warm during the experiment, so be careful with it.
- Be careful during work with soldering iron.
