LCD Serial Terminal Introduction: In the 1980s a serial terminal was a big thing with a picture tube and keyboard. You used it to communicate with a computer by RS-232 cable or with a modem. In this century, we still sometimes have need for a serial terminal, and we’ll typically use a personal computer running […]

I was trying to think of a suitable name for this project, and after literally seconds of careful deliberation, I gave up and decided to call it Fluffy. Sorry. Anyway, Fluffy is a SX programmer for people who havealready experimented with PIC chips, and want to try out the Scenix SX family. I built Fluffy

Built using a PIC16F84, about 4 hours worth of code and a few bits on a breadboard. This was the first time I’ve worked with PIC’s so it was a learning exercise. I started with the ‘Hello World’ microcontroller equivalent i.e. Blinking LED, then tried the ‘Knight Rider’ sequencing LEDs, and then hacked this together.

This text describes how to build my PIC16F84 based game system, before you start you should read through the whole text one time. Note that many components are sensitive to too much heat and will get damaged if you heat them too much when soldering. The drawn placement images show components to mount in each

Background Most multimeters can measure frequency, but they are not sensitive and the max frequency is not always so high. The same problem can be found with older frequency counters. This project will describe a prescaler which will work up to 2.5GHz and with very high input sensitivity. The prescaler will divide the input frequency

The photo shows a PIC16F84 microprocessor board tethered, by ribbon cable, to a circuit having 8 LEDs and an 8-position DIP switch. Learning a microprocessor’s capabilities often demands such a setup where LEDs turn on/off, blink at desired rates and respond to switches. This tutorial serves to quickly accelerate your PIC16F84 development ambitions. Motivation and

Cheap PIC Programmer This programmer works only with PIC16F84 but it’s great because it never causes errors and works with almost all computers,unlike some other homemade programmers. Step 1: Step one : Materials For this programmer you won’t need many materials.In fact , you will find all you need in your local electronics shop 😉

Background My friend Arthur, in his lifelong quest for circuits that don’t really do anything useful, but are really neat nonetheless, built a really neat Lissajous pattern generator. This Lissajous pattern is not your traditional circle, oval, or figure-8, it is a circle with varying amplitude, in a pattern that makes it look like a

This is an old design. Some of the components may be difficult to buy. If you would like to build an even better and cheaper A/D converter, take a look at the new PICADC3 design. The PICADC is a simple 12-bit, 8-channel analog to digital converter (with 4 additional digital inputs), which may be connected

The 16F84 is deserves looking at because it is the GranDaddy of PIC Microcontrollers but you should not use it for new designs (see Below)… The PIC16F84 is a the most well known and most well used of all the PIC microcontrollers – it is used in numerous projects that you can find across the web.
