Microchip PIC projects

list of projects

electronic combination lock

an electronic combination lock to use with an outdoor gate. It turns on a relay (usually to open a door) for a few seconds if someone enters the valid code. This relay can operate an electric strike or an electromagnetic lock. The code can be changed any time after entering the current code.

DIY wireless remote control

a general purpose remote control project using programmable PIC microcontrollers. Each channel can control a momentary or a toggle on/off output

infrared transmitter controlled by serial port

a programmable infrared (remote control) transmitter, which can be controlled from a PC serial port. It is capable of sending many remote control formats, including the Philips RC-5 standard

irrigation controller, timer

a simple one-valve irrigation controller made for a greenhouse. The code contains a software real-time clock (RTC) and a multiplexed 8-digit LED display and keyboard you can use in other projects

interface LCD with only 3 wires

interface a Hitachi HD44780 compatible LCD module to the PIC with only 3 pins used

Sona-PIC

measure distances with a Polaroid ultrasonic ranging module and send it over a serial port

stepper motor controller

control an unipolar stepper motor with 3 buttons: left, right, stop

ultrasonic range meter

measure distances with an ultrasonic transmitter and a receiver and display results on a 3-digit LED display

morse code decoder

decode morse codes from a microphone and print them on an LCD display
