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 […]

Build your own “2-Wire LCD Interface” using the PIC16C84 microcontroller
2-Wire LCD Interface for the PICMicro Alphanumeric LCD displays have become very popular for microcontroller applications because they can add a lot to a project in a variety of different ways. A text message giving the user instructions as well as feedback can make the application seem much more “professional” and easy to use. I […]
8 Channel PWM LED Chaser for 16F628A and 16F88
Description This neat little circuit provides 8 LEDs directly driven from the PIC along with a single mode control switch. The firmware elsewhere on this page drives the LEDs with a 5 bit PWM signal providing each of the 8 LED channels with four levels of intensity; off, dim, mid, bright. A number of sequences […]
Rubidium Atomic Clock
Introduction In the 1970s I worked for a while for the UK Atomic Energy Authority (UKAEA) at a site in Winfrith, Dorset. Amongst a lot of other interesting work, I used a gamma ray density gauge that amounted to a caesium-137 source, in its castle and collimator, the target (various), a sodium iodide detector (from […]
SMS Based Device Control using GSM Modem
It has been a while since we published electronic engineering projects here due to the busy schedule we had in the past weeks, and this time we’re up with another interesting project. Before going through the details of this one, you may as well check our latest electronics projects for engineering students. GSM based device […]
0-5V LCD volt meter using PIC16F877A
This PIC LCD volt meter project uses a PIC micro and an HD44870 LCD display. The analogue input is taken directly to the analogue input pin of the microcontroller without any other processing. So the input range is from 0V to 5V – the maximum source impedance is 2k5 (for testing use a 1k pot). […]
How to interface LEDs with PIC18F4550 Microcontroller
It is necessary to understand basic I/O operations of PIC18F4550 before dealing with its complexities. This article presents a way to take simple output from a PIC microcontroller. This learning would also help in interfacing of external devices with the controller. Here the output from the microcontroller is taken on a set of LEDs which […]
Simple Digital GPS Speedometer Using PIC16F877A with LCD Display
Speedometer is a speed measuring gauge used to calculate the speed of motor vehicles. They are mainly of two types- electronics and mechanical. Digital speedometer measures the speed and mileage in vehicles. Normally both types work on the principle of electromagnetism, however they have a disadvantage that they cannot be used if there are no […]
Electronic Die using PIC16F84 microcontroller
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. […]
Servo Motor Control using Microcontroller PIC16F877A
Servo motors are widely used in robotics and industries for motion control. They can be controlled by PWM signals where the required angle of rotation can be located by a particular PWM signal. So In this article we’ll see in detail on PWM servo control and how servo motor control using pic16f877a is possible. Servo […]
