Activity 5 conducted at 13th Aug 2022.

Required Material:-

  1. Arduino UNO
  2. Pressure Sensor
  3. Jumper Material
  4. Arduino IDE
  5. 1K resistor
  6. LED bulbs
  7. Breadboard
  8. Aluminium foil
  9. Paper Tape

In Pulse Detector firstly we have demonstrated how to make pressure sensor. Which is made by using aluminium foil and paper tape. Also we have showed in video.

Activity Outcomes:-

  1. Student will understand the concept of pressure sensor.
  2. Student will understand how to connect pressure sensor to arduino.
  3. Student will learn the polarity of LED’s.
  4. Student will learn connection between led’s and arduino.
  5. student will learn interface of arduino ide.

In this Activity, students learned to detect the pulse using finger clips as sensors and Arduino UNO.

When the two finger clips with aluminum foil are put up on the index finger and middle finger it becomes a conductive material and sends the pulse towards Arduino in analog form, being a Microcontroller Analog data received from finger sensors is processed and uploaded on Serial Plotter. Therefore the data given by the fingers is seen on the Serial Plotter and also blinks the LED (as red, blue, green)according to the pulse rate with the help of Arduino Programming.
