This project is a miniature Audio CRO. For those not familiar with the abbreviation “CRO,” it means “Cathode Ray Oscilloscope” and this is sometimes shortened to “SCOPE or O-Scope.” A “CRO” is a piece of test equipment with a screen. It produces a visual indication of a waveform, via a probe, when the waveform is […]
Servo motor driver tutorial. This tutorial uses the 12F675 microcontroller to drive a servo. The microcontroller generates the signals to control a standard servo using Timer 0 interrupts (I used a Futaba servo). It does not do anything clever just sets the servo position to predefined positions at one second intervals. A Timer 0 interrupt

Led indicators for on off status 5. Can be Rf controlled 6. Can be serially controlled 7. All code Flow charts
Based on the idea from http://www.josepino.com/pic_projects/?timebaseI have created a 1Hz Clock Generator. I use PIC12F675 as it’s available locally. Its price is just about US$1. The concept is using 32.768kHz crystal as a clock for the PIC. Therefor, the internal instruction clock is 32768/4 = 8192 Hz. By using the 16 bit Timer1 to count
Power Pic RGB with Infrared remote controlis a circuit that generates colors using a RGB LED and can be controlled using any infrared remote controller capable compatible with the Sony® Sirc code. This circuit is the third evolution of Pic RGB project [1] in which the goal was to control a RGB LED and randomly

This post provides the PWM code for PIC12F675 microcontroller using timer0. There are many uses for PWM signal, e-g you can control dc motor speed using PWM. Timer0 is initialized in the start of the main function and using timer0 interrupts, PWM is generated. This code is written in C language using MPLAB with HI-TECH C compiler. You
