Introduction

  • In this article, I explain about Heart Beat Pulse checking through the Arduino Mega. It can easily display the wave on a PC monitor.
  • In the PC monitor, it displays the reading of the pulse.
  • The wave form can be displayed in the sine wave form.
Parts Of List:
  • Arduino Mega
  • Easy pulsev1.1 sensor
  • HRM-2511E
  • Hookup wires
  • PC.
Connection:
Step 1: Connection from the Easy pulsev1.1 sensor to Arduino mega.
Figure1: Easy pulsev1.1
  • Connect the Vcc in the Easy pulse v1.1 sensor to the Vcc of the Arduino Mega.
  • Connect the Gnd in the Easy pulse v1.1 sensor to the Gnd of the Arduino Mega.
  • Connect the Ao in the Easy pulse v1.1 sensor to the Ao of the Arduino Mega.
Figure2: connection of HRM-2511E to Easy pulsev1.1
Connect the HRM-2511E and Easy pulsev1.1 in the power cable.
Programming
  1. void setup()
  2. {
  3. Serial.begin(115200);
  4. }
  6. void loop()
  7. {
  8. int sensorValue = analogRead(A0);
  9. Serial.println(sensorValue);
  10. delay_x(5);
  11. }
  13. void delay_x(uint32_t millis_delay)
  14. {
  15. uint16_t micros_now = (uint16_t)micros();
  17. while (millis_delay > 0)
  18. {
  19. if (((uint16_t)micros() - micros_now) >= 1000)
  20. {
  21. millis_delay--;
  22. micros_now += 1000;
  23. }
  24. }
  25. }
  27. void setup()
  28. {
  29. Serial.begin(115200);
  30. }
  32. void loop()
  33. {
  34. int sensorValue = analogRead(A0);
  35. Serial.println(sensorValue);
  36. delay_x(5);
  37. }
  39. void delay_x(uint32_t millis_delay)
  40. {
  41. uint16_t micros_now = (uint16_t)micros();
  43. while (millis_delay > 0)
  44. {
  45. if (((uint16_t)micros() - micros_now) >= 1000)
  46. {
  47. millis_delay--;
