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.

What is PWM

What is PWM

While ADC is used to read Analog signals by a digital device like microcontroller. A PWM can be considered as an exact opposite of it, PWM is used to produce Analog signals from a digital device like microcontroller. In this article we will learn about what is PWM, PWM signals and some parameters associated with it, so that we will be confident in using them in our designs.

Thermal Printer interfacing with PIC16F877A

In this tutorial, we will interface a thermal printer CSN A1 with widely used PIC microcontroller PIC16F877A. Here in this project, a thermal printer is connected across PIC16F877A and a tactile switch is used to start the printing. A notification LED is also used to notify the printing status. It will glow only when the printing activity is going on.

AT89S52 8-bit Microcontroller

The AT89S52 comes from the popular 8051 family of
Atmel Microcontrollers. It is an 8-bit CMOS microcontroller with 8K as
Flash memory and 256 bytes of RAM. Since it is similar to the trust
worthy 8051 architecture these microcontrollers are as per industry
standard. It has 32 I/O pins comprising of three 16-bit timers, external
interrupts, full-duplex serial port, on-chip oscillator and clock
circuitry.

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.

Programming STM32F103C8 Board using USB Port

Programming STM32F103C8 Board using USB Port

In our previous tutorial we learnt the basics of the STM32 Development Board and also programmed it to blink an LED. But there was one huge drawback with it. In order to program the Board we utilised a FTDI programmer module and also had to toggle the boot 0 jumper between and 1 position while uploading and testing a code, which is surely a daunting task. Also the mini-USB port on the Development board was left totally unused. The reason for doing that is, when the STM32 development board is purchased it does not come with an Arduino ready boot loader and hence the board will not be discovered by your computer when connected through the USB.
