PICList Projects

These projects have come from the PICList community. They are good general purpose usefull projects for beginners with lasting value for the experts and great code samples to augment the routine library.

Delay Code Generator

Brendon Archibald's Psychoanalytical (restarting countdown) Timer

Simple Bike Computer by Fred Maher

From the CHEAPIC tutorial:

• bincnt.asm - Count in binary on 4 LEDs
• swcnt.asm - Count switch closures.
• eggtimer.asm - Countdown timer, displays minutes and 10's of seconds on LEDs
• morsenbr.asm - Send numbers 0-9 out on piezo speaker
• binclock.asm - A clock which displays hours and minutes in BCD on LEDs at keypress
• combo.asm - a combination lock which remembers a selectable combination, even when power is removed
• alphabet.asm - Sends ASCII characters to the COM port of a PC for display
• worktime.asm - Uses a LCD to display a timer that can be started and stopped by pushbutton
• shotmr0.asm - Display TMR0 on a LCD atter counting pulses on RA4 for one second
• therm.asm - Display temperature on a LCD using a thermistor as the sensor

• http://www.sskteracon.com A small home controller based on PIC16F873A. With the appropriate sensors the controller can monitor physical variables such as pressure, temperature, light intensity etc, process the information and then use the result to control up to three physical devices such as motors, heaters, lights or other appliances around the home or office. You can program your appliances to operate automatically in conjunction with your weekly and daily schedule, manualy turn them on/off from your PC or use the controller as a process ON/OFF controller to regulate some kind of physical variable to the desired value.

Questions:

• imythili18 at yahoo.com asks: " I have seen the instruction set for a A/D converter for 16F873.
  Can i apply the same program for 16F88? Or if there are any changes what are they?" >> James Newton replies: Check the datasheet.
