Direct Digital Synthesis (DDS) using PIC16F84 microcontroller
Background DDS stands for Direct-Digital Synthesis. This synthesizer is simply a circuit that can create a sine- wave signal from a reference crystal and a programable frequency-register. All this circuit …
DDS/PLL based VFO synthesizer using PIC16F876
DDS (Direct Digital Synthesized) VFO seems to be very popular among amateurs in last few years, mainly thanks to cheap and easy available single-chip DDS synthesizers. There are plenty of …
Brushed Motor ESC using PIC12F675 microcontroller
Background There are a number of other projects that have been documented for brushed motor ESCs. The good starting point for other ESCs is this rcgroups thread. The information in …
GTP USB PIC PROGRAMMER (Open Source) using PIC18F252
GTP USB PIC PROGRAMMER (Open Source) This work includes, GTP USB (not plus or lite) . The schematic, photos and PCB have been developed by PICMASTERS based on some valuable …
VIRTUAL HOURGLASS TIMER
INTRODUCTION Time-keeping is inherently stressful, especially when you can see the seconds ticking down. The Virtual Hourglass Timer takes all the pressure away through its relaxing visual display. Inspired by …
Countdown Timer using PIC16F84 microcontroller
It’s a kitchen timer. Use it to time spaghetti, or maybe an egg. It uses two PICs, one acts as a keyboard encoder, the other drives the display and supports …
Grid Powered Battery Charger – The Plans using PIC16F676
You get a really good feeling when you plug in some lights and appliances and power them with your own electricity from the sun or wind. You get a really …
Infra/radio remote control transmitter/receiver with PIC16F630
description This is a general purpose remote control project with using programmable PIC microcontrollers. Schematics are shown for using infrared (RF) or radio (RF) media. If you are not familiar …
Writing Robot Arm
Introduction In this project, we built a writing machine using a 4-DOF robot arm. This robot arm is controlled by PIC32 and can write the 26 letters and ten numbers. …
NOPPP, the “No-Parts” PIC Programmer using PIC16F83
NOPPP is a simple programmer for PIC16C84, PIC16F83, and PIC16F84(A) microcontrollers. It attaches to the parallel port of a PC. Plans were published in Electronics Now Magazine, September, 1998, and …
