MikroElektronika’s “Ready for PIC” board talks to “Processing” using PIC16F887

“Ready for PIC“ is one of MikroElektronika‘s compact prototyping boards for 28 and 40 pin PIC microcontrollers. The board comes with PIC16F887 microcontroller which is preprogrammed with an UART bootloader firmware and thus eliminates the need of an external programmer. The on-board USB-UART module allows the serial data transfer between the PIC and a PC using an USB cable. It has also got a reasonable size ...

PBUS – an RS485-like multi-drop bus with half duplex serial protocol

overview There are three PIC source versions: PB12 is for 12-bit slave devices without interrupt PBUS is for slave devices with an interrupt, software UART implementation PB628 is for slave devices with an intterupt and a free hardware UART PBUS assigns a unique device ID in the range 1-f for every controller on the bus. The maximum number of slave devices on one bus is maximized in 15. Current protocol is ...

Chronograph for Air Cannon using PIC16F628A microcontroller

Intro: Chronograph for Air Cannon This chronograph project consists of a sensor assembly and timer circuit box that can be used to measure the muzzle velocity of a projectile fired from an air cannon. I originally built this setup for use with a large air cannon with a 3" bore. The sensor assembly is attached to the end of the air cannon barrel. It contains infrared sensors used to detect the passage of the ...

Poor man’s counter using PIC16F84 microcontroller

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 with either 1000 or 10.000. The divided output signal is 0/5 volt and can ...

The Talking Breathalyzer Mark II using PIC18F1220

The Talking Breathalyzer Mark II Hi Folks! Thanks for having a gander!  This is my second Breathalyzer project.  IT TALKS TO YOU, and gives you an idea of how much you've had to drink! I made it specifically for for this contest.  I hope you all like it.  From a block diagram point of view, it consists of a DC power regulator circuit, an analog alcohol sensor + driving circuit, an audio recording and playba ...

Rotating Sprocket Wheel Generator using PIC16F84

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 sprocket. Not satisfied with that, he also made it so that the sprocket ro ...

A modified version of the “Air diplay” adapted to be used in a bicycle using PIC12F629 microcontroller

Anthony from Cumaná, Venezuela, made his own "Persistence of vision" (POV) display, similar to my Air Display but it can be mounted on any bicycle wheels and it displays fifteen messages in Spanish. Here is the PCB with each part of the project. It uses a 12F629, works with a voltage of 3Volts This is the PCB top view to determine the location of each part. The yelow ones are the resistors, the red ones are ...

Daft Punk Table Replica Graphics Controller using PIC18f2550

Daft Punk Table Replica Graphics Controller This instructable presents a graphics controller card for something like the Daft Punk Table Replica. This should be used in conjunction with a driver board (output expander) like this one, which will drive the high loads presented by the table. This is a work in progress and collaborations on this instructable are welcome. *audio used under creative commons licen ...
