PIC microcontroller based fastest finger press quiz buzzer project

The fastest finger press quiz buzzer is very popular in school, Collage, different T.V. show, different quiz competition. Here in my pic microcontroller based fastest finger press quiz buzzer project you will find four tables with push button. For any instant if four teams on four tables press the push button then it will glow the light and blow buzzer of that table for fasted finger press. Project descript ...

The Annoy – A Tiny Intelligent Buzzer using PIC10F202

A while back I made a blog post about a PIC10F200 Project: The Annoy. In this project they combined the simplicity in design along with the creativeness that I always look for, into a project with no real use other than for fun. However, the project seemed a little too large and we felt we could improve upon it, so let's get to it! In this article we will take a look at the original, 'The Annoy' project, an ...

PIC sound player (PCM to PWM converter) using PIC18F1320

Description This project makes a PIC microcontroller play audio PCM sounds using PWM modulation! Pulse-code modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a digital (usually binary) code [1]. Pulse-width modulation (PWM) of a signal or power source involves the modulation o ...

DTMF Touch Tone Decoder Using Microchip PIC Microprocessor using PIC12F683

DTMF Touch Tone Decoder Using Microchip PIC Microprocessor This project contains the details of using a Microchip PIC12F683 8 bit microprocessor to detect DTMF tones. The completed program allows the processor to be programmed with a string of DTMF tones to detect. If the programmed string is detected in the audio applied the audio input, the output will turn on (go high), and can be used to control other c ...
