Heart Beat Monitoring using PIC Microcontroller and Pulse Sensor

Heart Beat rate is most important parameter in monitoring any person’s health. In the modern era of wearable devices, there are lot of devices which can measure heartbeat, blood pressure, footsteps, calories burnt and lot of other things. These devices has pulse sensor inside them to sense the pulse rate. Today, we will also use a pulse sensor with PIC Microcontroller to count heart beat per minute and the Inter-Beat Interval, these values will be further displayed on 16×2 character LCD. We will use PIC16F877A PIC microcontroller in this project.

RFID Interfacing with PIC Microcontroller

RFID Interfacing with PIC Microcontroller

To read the Passive RFID cards and tag, we need a microcontroller with UART hardware. If we select a microcontroller without UART, we need to implement software UART. Here we are using PIC Microcontroller PIC16F877A for interfacing RFID. We will simply read the unique identification no. of RFID tags and display it on 16×2 LCD.

STM32F103C8 ADC Tutorial – Measuring Analog Voltage

The ADC embedded in #STM32 microcontrollers uses the SAR (successive approximation register) principle, by which the conversion is performed in several steps. The number of conversion steps is equal to the number of bits in the ADC converter. Each step is driven by the ADC clock. Each ADC clock produces one bit from result to output. The ADC internal design is based on the switched-capacitor technique.

ESP32 Internet Clock

To minimize hardware requirements we will make Internet clock without using RTC module. This is more accurate as compare to RTC clock. ESP32 is a Wi-Fi module and can be easily connected to the internet so we will use NTP (Network Time Protocol) and UDP (User Datagram Protocol) to fetch Time from the internet using Wi-Fi.

DIY Speedometer using Arduino and Processing Android App

In this project we make a Cool Speedometer for bikes or any automotives by using Arduino which broadcast the speed using Bluetooth to an Android application that we created using Processing. The complete project is powered by an 18650 Lithium cell and hence highly portable along with your vehicle. To spice it up a bit more I have added the option of charging your mobile phone as it displays your speed. Yes, you can also use this as a power bank for your mobiles on the go as the 18650 has high charge density and can easily be charged and discharged.

PIC Microcontroller PWM Tutorial

In this tutorial, we learn How to generate PWM signals using PIC PIC16F877A. Our PIC MCU has a special module called Compare Capture module (CCP) which can be used to generate PWM signals. Here, we will generate a PWM of 5 kHz with a variable duty cycle from 0% to 100%. To vary the duty cycle we are using a potentiometer, hence it is recommended to learn ADC tutorial before starting with PWM. PWM module also uses timers to set its frequency hence learn how to use timers beforehand here.  Further, in this tutorial we will use a RC circuit and a LED to convert the PWM values to Analog voltage and use it for dimming the LED light.
