This post provides an example code to use PIC16F84A pins as inputs. After going through this example, you will understand how to make PIC16F84AÂ pins as inputs and how to read their value in the code. This code is written in C language using MPLAB with HI-TECH C compiler.You can download this code from the ‘Downloads‘

HOW DOES IT WORKÂ & CIRCUIT SCHEMATIC Everybody knows the speed of the sound in the dry air is around 340 m/s. Send a short ultrasonic pulse at 40 Khz in the air, and try to listen to the echo. Of course you won’t hear anything, but with an ultrasonic sensor the back pulse can be

The synchronizer ensures a contact-free, optical synchronization of external photographic flashguns. The triggering of the external flash is derived from embedded flashes of a camera. It can be used for both digital and “analogous” cameras or for a remote synchronization of the actual flash units. Its use is optimal especially with digital cameras (DC), where
For a while we have been sharing many electronic projects for engineering students and then we found out there was a huge demand for embedded projects, especially PIC microcontroller based projects. After a short break, here is another outstanding one that is not only suitable for electronics engineering but mechanical engineering students too. Now coming

This project has only a few modifications from the âSingle Chip, Four Channel Dataloggerâ article by Dan Gravatt in the 2008 January Issue of Nuts&Volts (page 42), so I wonât go into much detail. Below is the schematic. The changes from Danâs datalogger are that I used the PIC16F886, which is pin-compatible with the PIC

At the start of this series of posts, I said I did not want a PC to control my Milling Operations, so some local delivery method of supplying the gcode files is required. Having said that, the system is âopenâ, and a simple XON/XOFF terminal program running on a PC can be used if required.

Aurora 9 bar – The Essence of Aurora Since the introduction of Aurora 9×18, I received many requests for the kits and PCBs. I’m still quite undecided about making those available for a few reasons. However I really want other LED lovers (ok that might sound too much to be able to build one themselves.

The Compact Flash Library provides routines for accessing data on Compact Flash card (abbr. CF further in text). CF cards are widely used memory elements, commonly used with digital cameras. Great capacity and excellent access time of only a few microseconds make them very attractive for microcontroller applications. In CF card, data is divided into
