How to Connect(Wire) DC Buzzer with 9V Battery & Switch | How to Make a Simple Electrical Circuit
The following items are required to build this circuit:
9-Volt Battery Snap
9-Volt Battery
Two wires
DC Buzzer
Breadboard
First, place the 9-Volt battery snap in the breadboard, the red wire going to the positive side, and the black going to the negative. Connect the black wire from the negative to the board. Next, place the buzzer right beside the wire facing horizontally.
Lastly, Connect a wire from the buzzer to the positive side. Now you have your circuit! The last thing you have to do is test it out.
This project can serve as an introduction to circuits for teenagers from approximately 14-16 years old. It involves the creation of a buzzer game. During the construction, learners develop basic knowledge of electrical circuits, base level engineering, sensors and design.
If you like puzzles, this whole project is a series of puzzles. But none of the parts are impossible, so get into it with confidence! It is a perfect engaging learning activity that is so much fun that it will feel like a hobby!
This activity was created in the context of a challenge I participated in at the Concordia University Innovation Lab under the supervision of Dr. Ann-Louise Davidson, in collaboration with Lower Canada College (Mentor: Alec Mathewson) and Chalet Kent (mentor: Karl-André Saint-Victor).
This activity was created alongside Sut Wing Mok, Tejas Patel, Ahmed Yasser and Leila Rhazi at Concordia University.
The best thing about this activity is the construction. Make sure you have all your supplies handy before you start! Here's a list of all the things you will need. Keep in mind these are just examples! Alternatives and workarounds are encouraged. You can use your creativity to replace them with items that you have at your own home or workplace or that you can dig out from broken electronics or appliances.
Now comes the first puzzle part. By the end of step 2, you’ll end up with 5 board pieces.
First, measure and mark the boards using the ruler and pencil to these measurements:
Board 1: Length x Width (50cm x 25cm)
Boards 2+3: Length x Height (x2) (50cm x 5cm)
Boards 4+5: Width x Height (x2) (25cm x 5cm)
Then, using these lines as reference, cut the boards along the measured lines.
You are now ready to glue the pieces together! Start from the bottom and work your way up from the base. Take your time, and make sure the glue sticks to the boards.
This is the most fun step, as you can use your creativity and challenge yourself or your friends for the best design! You only need to make sure that a stick tied with a wire loop can move around the whole design from the beginning till the end smoothly. The rest of it is totally up to you!
First, strip the wire by removing the outside plastic casing.
Second, bend and fold the wire to your design. You can use your hands, or pliers if it’s too difficult.
Step 4: Bringing It Together
Let’s get into the fourth step of this assembly. You are going to be drilling a lot of holes for everything to be put together. Using the drill, you will make:
- 1 hole for the buzzer
- 1 hole for LED (right beside the buzzer)
- 1 hole for switch (right beside LED)
- 1 hole for a thin wire (several cm from the switch)
- 2 holes for the thick conductor wire (one on each side, opposite ends)
Insert the thick conductor into the holes you created. Place the components (LED, buzzer, switch) as shown in the photo.
Note: make sure that the buzzer and LED are placed the same way for polarity! The longer pins of both components (positive) are one the upper side and the shorter pins (negative) are down!
Here is the whole idea: When the stick touches the thick conductor, it will close the circuit - the buzzer will ring and the LED will turn on. When it isn't, the circuit is open - the buzzer will not ring and the LED will not turn on.
Next you will use the soldering iron to do the following connections:
- Connect the negative side of the battery connector (black), to the (in) side of the switch and from the (out) side of the switch, connect it to either side of the resistor. From the other side of the resistor, connect to the negative side of the LED and the negative side of the buzzer.
- Connect the positive side of the battery (red) to a gauge wire (this will be the stick) and leave it there.
- Connect the positive side of the LED to the positive side of the buzzer. Then connect to either side of the thick conductor (the closer end) as shown.
Now, guess what happens! If the gauge wire touches the thick conductor, the circuit will close and the alarm and LED will turn ON. (Note: if the switch is open.)
From the same thick conductor that we previously shaped in Step 3, we’ll now create a circular stick as shown below. (Note: the smaller the circle, the more difficult the game will be!)
Use the soldering iron to connect the gauge wire to this stick and cover it with electrical tape or t tape. This is for safety and so that it’s easier to hold.
You may also duct tape the thick conductor from the two sides on top so that the circuit remains open even if the switch is ON and no one is using it.
Step 6: Let The Games Begin!
Play around and challenge your friends! The one with the least amount of buzzes to reach the end, wins!
Watch a little demo video of us playing the game.
Now that you have implemented all the previous steps, you have achieved the learning outcomes! Was it too simple?
If it was, then this section is for you!
You have learned how the circuit components can be implemented (positive and negative), the effect of high power on components and how to regulate them (resistors!), how different designs can change the whole thing (mini ties -> hard, bigger ones). -> easier.) and how a run through can show you the drawbacks of your design if it will work or not.
Use this knowledge to do something different. Solve an issue at home, such as... Do something more fun, such as... Learn about different components. Here are some ideas on how to go from what you have achieved and enhance your skills!
Extension ideas:
Arduino board to do some specific commands as programmed, ex:
- Buzzer to alarm for a few seconds continuously when the conductor is touched.
- Count how many touches and display them by the end.
- LED to blink when a specific number of tries are reached.
Insert some bigger obstacles on the conductor wire and adjust the design (of course they need to be electrical conductors too!)
