Description This circuit can be used to operate an electric strike or an electromagnetic lock on a door. It is not the door being opened/closed, but a small electromagnetic strike which unlocks the door. The opener has the following features currently programmed in software: automatic operation when a guest pushes the doorbell, the strike is […]

10 tricks for interfacing to the PIC16C508
Most of the ideas in this chapter can be found on the pages of this website, but just in case you want to go over the capabilities of the ‘508A, we have brought them together. Quite often when you are programming, the first thing you will run out of is output lines. Many projects need […]
EMDP1 — Extensible Multiple Device Programmer 1 (Rev. C) using pic microcontroller
Table of Contents Table of Contents Introduction Schematics Printed Circuit Board Issues Introduction This is revision C of the EMDP1 mother board. It differs from revision B in that a 40-pin ZIF (zero insertion force) socket and an 80-pin `universal’ plug have been added. This allows many chips to be programmed without requiring an adaptor […]
Very Accurate LC Meter based on PIC16F628A
About Accurate LC Meter This is one of the most accurate and simplest LC inductance / capacitance Meters that one can find, yet one that you can easily build yourself. This LC Meter allows to measure incredibly small inductances starting from 10nH to 1000nH, 1uH to 1000uH, 1mH to 100mH and capacitance from 0.1pF up […]
DIY MIDI controllers using PIC microcontrollers and Basic Stamps using pic microcontoller
Introduction By combining a PIC microcontroller or Basic Stamp II with a few passive components it is not difficult to construct your own knob box, trigger box, or other MIDI input device. A knowledge of electronics may be required for interfacing to some sensors. Both the Stamp and PIC provide an economical (under US$100) entry […]

Obstacle Sensing Walking Stick for Visually Impaired Persons : Block Diagram
From the block diagram given above you can see that this project has four major parts. The Power Bank Finding a good power source for this project was a challenge, the power supply should have to be mobile, so that we cannot use power adapters. Also it had to be rechargeable so that it is […]
GPS-based universal clock generator using PIC16F628
GPS satellites and GPS Ground Segment need extremely accurate timing to allow GPS users to know their own position on the Earth. Rubidium and Cesium clock generators are extensively used and maintained to synchronize and generate the signals that our inexpensive navigator gets from the GPS satellites orbiting at 20000 Km. Many commercial systems use […]
