PIC based WWVB clock

Introduction There are many DIY versions of WWVB clock designs available on the web. Commercial "atomic" clocks are inexpensive and widely available, but I wanted to try my hand at designing one to gain insight into WWVB reception and to learn a little about programming a PIC microcontroller. My version is not the simplest available, but it works well and I think it offers a few unique features. WWVB Clock ...

PIC Based Message wand

The project uses flashing LEDs to present shot message in the air by swinging a wand around above the head. A perfboard is used to construct the circuit that is powered by 2 coin cells type CR2016. The power fluctuations from excessive load on the coin cells can be prevented using the electrolytic capacitor. A toothbrush holder is used to make the message wand since swinging around the exposed sharp edges o ...

PIC10F200 based dice

This page describes a PIC10F200-based electronic dice. The reason I made this was that I got a small corner left over when ordering a panel with a couple of other PCBs and thought I would rather use the corner for something fun than leave it unused, so I made a dice. The PCB is quite small, so it is hard to etch yourself even the layout is available in the zip-file if you want to try, so to make it easier f ...

Two-Channel PC Based Oscilloscope USB

Inroduction More and more experiments are now ‘PC-assisted.’ Also conventional acquisition systems are very expensive. Since portable  PCs are today common and a USB link is a better solutionhere we present an oscilloscope using USB port of the PC that operates at up to 10 kHz with ±16V input voltage. It has much more improved features than the PC-based oscilloscope . The oscilloscope uses IC PIC18F2550 fro ...

PIC Based Oscilloscope Clock

For those are not into electronics, you must know that an oscilloscope has basically only one timebase to move the spot horizontally from left to right with the same intensity. The vertical deviation is function to the input voltage. You understand immediately that you can't directly display 7 segment digits, because you can't move the spot from right to left. By using X/Y mode, where the spot is controlled ...

Ways to Select a Best Microcontroller for Microcontroller based Projects

Do you know how to select the best microcontroller for microcontroller based projects? Selecting the proper microcontroller for a given application is one of the most critical decisions, which controls the success or failure of the task. There are different types of microcontrollers available and if you have decided on which series is to use, you can easily start your own embedded system design. Engineers m ...

Microcontroller based Morse Code Generator with Applications

The term Morse Code generator is an ancient language, used to transmit the data or information in the form of a series of ON/OFF buttons. This language can be directly understood by a skilled observer who knows the Morse code without any special devices. Understanding of this language is very difficult for the people. Because, this code is denoted by a unique series of dots & dashes or dahs & dits. ...
