Analog to Digital Converter

Using ADC of PIC Microcontroller – MPLAB XC8

In this tutorial we will learn, how to use the ADC module of a PIC Microcontroller using MPLAB XC8 compiler. For demonstration we will use the commonly available PIC 16F877A microcontroller. Every physical quantity found in nature like temperature, humidity, pressure, force is analog. We need to convert these analog quantities to digital to process it using a digital computer or a microcontroller. This is done by using Analog to Digital Converters. An Analog to Digital Converter or ADC is a device...

Monostable Multivibrator using Transistors

Multivibrator is a non linear oscillator or function generator which can generate square, rectangular and pulse waves. Monostable Multivibrator or One-Shot Multivibrator has only one stable state. By default monostable multivibrator will be in its stable state, but when triggered it will switch to unstable state (quasi-stable state) for a time period determined by the RC time constant in the circuit.

PWM - Pulse Width Modulation

Generating PWM with PIC Microcontroller – MPLAB XC8

Pulse Width Modulation (PWM) is the one of the simple and most commonly used technique to produce analog voltages from digital signals. It has a wide variety of applications such as Digital to Analog Converter (DAC), DC Motor Speed Control, Sine Wave Inverters, Brightness control etc. PWM signals are ON - OFF signals (HIGH or LOW) (hence the name Pulse) whose HIGH or ON duration is changed (hence Width Modulation) in accordance with our requirements. The fraction of time period for...
