My Class @ NJIT Final Projects

I got an opportunity to teach Arduino to the BME graduate class this spring. It was a great experience. Since, it was a hands-on class, the students were expected to do a final project. Here are some of the projects that my students did.

1. Blind Aid

  • The basic idea was to use a ultrasonic trasducer as a transmitter and receiver to gauge the distance of the obstacle from the subject.
  • A piezo was used whose intensity and pitch increased inversely with distance of the obstacle.
  • A vibrating motor was also used to give the subject haptic feedback.
  • The entire setup was controlled using Arduino and was mounted on a Bandanna. 
2. Arduino-Based Ignition Interlock System
  • The project used an alcohol sensor to detect the alcohol content in the driver's breath.
  • Depending on the alcohol content Arduino allows or prevents the operator from driving the car by controlling a relay attached to the car's ignition system

 
 


3. Arduino Based R-wave detector for Heart -rate calculation
  • This project used arduino to count R-R interval of the ECG signal and displayed the instantaneous HR and HR averaged over 1 min on a 16 X 2 LCD screen.
  • Patient simulator was used for ECG and grass amplifier was used for amplification.



4. Arduino based Oral cancer detection system
  • Oral cancer largely caused due to excessive consumption of oral tobacco affects a large population of people especially in developing countries.
  • This project envisioned to estimate the chances of a person having a oral cancer by measuring amount of extension of the jaw and the speed with which the person can open his/her mouth.
  • Since these parameters are different between healthy and subjects with high risk of oral cancer it can be used as a preliminary test by the doctor before recommending further testing for the patient.
 
 


5. Heart Rate measurement using Electronic Stethoscope
  • Since the Electronic stethoscope is highly sensitive to body sounds it can be used to record the sound of the ventricle contraction ( R wave in ECG). This signal is filtered, amplified and fed to Arduino to calculate Heart rate.
  • Heart rate is displayed in 16 X 2 LCD.


Thank you class...it was a pleasure working with all of you.....
