Roles
- Yaad Aulakh - I made the covering of the micro:bit to cover the device and wiring by cutting of cardboards and also helped in putting the device and sensors in place, making sure that the sensors are placed in proper positions so they can detect chips and cards. I helped in gluing of layers of table. Moreover, I helped in decoration by putting cards and pokerchips on the poker table. Futhermore, I built the webpage for project showcase.
- Keya Sital - I helped cut the bottom and top boards into the circle shape and I glued multiple layers of cardboard together to achieve the correct height and ensure the structure was durable. Also, I painted the board with multiple layers to create a realistic finish and colored the wiring black for to help make the wires easy to identify. Moreover, I helped decorate the table for the project presentation. Futhermore, I helped in the content for the webpage.
- Chijioke Nwagwu - I helped with cutting of the cardboards into shape of different parts and helped to decorate the table and wired the components I developed the code on the makeCode application. I designed the positioning and dimension of the magnets and hall sensors to ensure alignment. Futhermore, I helped in the creation of the documentation for the webpage.
Information
Components Used:
- Microcontroller: BBC micro:bit
- Hall Effect Sensors: Connected to pins P0 and P2 to detect magnetic fields
- Built-in Speaker: Produces a sequence of beeps
- LED Display: Shows sensor readings and alert codes
- Magnets: To introduce magnetic fields into the system
Inputs:
- The device reads values from two Hall Effect sensors connected to P0 and P2
- These sensors detect the presence or absence of a magnetic field.
- If both sensors register a value below 50, the system initiates a countdown sequence.
Outputs:
-
The LED matrix displays:
- The current sensor readings from P0 and P2.
- The number 321 when the condition is met.
-
The built-in speaker plays a specific beeping pattern:
- 3 short beeps
- Pause
- 2 short beeps
- Pause
- 1 short beep
- Pause
- 1 long beep to mark the end of the sequence
Purpose:
- This system is designed for magnetic field detection and notification. It is a part of a lager Casino Heist system. It's implementation is to detect the presence of a magnetic field then transmit a signal accordingly. The value of this signal could be manipulated to carryout a function and in the case of our project, it displays a secret code (321) with a corresponding beep pattern.
- This principle could be used in a variety of ways. Take for instance, in an alternating current generator, a magnetic field is generated based on the flow of current through a rotor. This device we built could also be integrated to detect if the magnetic field is being generated or not. It could also be used to display the value of the magnetic field. The possibilities limitless. They could also be integrated into security devices to detect the movement of objects that have some magnetic properties.
