Our project was to create a double Tansducer that converted a magnetic field strength to a printed color output. To accomplish this, we chose two middle steps to convert the input signal to the output.<\/p>\n

Project Details<\/h2>\n
\"\"

This three-axis magnetometer senses the strength of a magnetic field in 3 dimensions.<\/p><\/div>\n

\"\"

Shown is the Stepper Motor Driver. This provides the “brains” of the stepper, controlling direction, rotation angle and speed the motor rotates at.<\/p><\/div>\n

\"\"

The Stepper Motor is attached to a rack and pinion system that slides back and forth depending on how strong the magnetic field is. The system slides on a piece of acrylic to reduce the kinetic friction between the 3-D printed material and the cardboard surface.<\/p><\/div>\n

\"\"

The Ultrasonic Ranger detects how far the rack is using sonar, and sends the signal back to the Arduino. The ranger is soldered to a soldering board with a screw terminal soldered on behind it, making it easy to connect wires since they don’t move around as our transducer is at work.<\/p><\/div>\n

\"\"

The Arduino maps the distance measurement to an angle and instructs the Servo Motor to rotate to the specific angle accordingly.<\/p><\/div>\n

\"\"

The rotation of the Servo Motor reveals a part of the color gradient as it rotates. This color output is then read by the next group’s transducer.<\/p><\/div>\n
