PIC16F
Simple PIC programmer
10. August 2008 - 12:38 — adminIt is a modification of a JDM-Programmer. This PIC-programmer has to be connected with the serial com port of your computer.
PIC-based real-time clock with DS1307
27. July 2008 - 12:02 — adminThis PIC project uses an I2C Real Time Clock IC (DS1307) and a four digit seven segment display to create a standard desk clock.
Nano GPS logger
28. June 2008 - 13:19 — adminThis is a small GPS logger based on the San Jose Navigation FV-M8 GPS module that stores coordinates, altitude, and speed into an EEPROM.
LCD display for GPS module
27. June 2008 - 15:57 — adminA cool and creative way to combine the PIC Programming with the GPS LCD display.
DC motor speed control using PWM
25. June 2008 - 20:20 — adminDC motor speed control based on PIC16F867.
The circuit is using PWM with frequency about 10kHz, which does not make a noise in the motor. This project can drive motor with 1A current without heat. The motor speed is controlled by potentiometer which is connected to ADC input of PIC16F867.
LM75 Temperature Sensor
24. June 2008 - 17:59 — adminSimple LM75 temperature sensor on the breadboard
Tiny PIC bootloader
12. June 2008 - 13:57 — adminThis is a bootloader for the Microchip PIC microcontrollers.It is the smallest bootloader, taking less than 100 words of program space and Supports families of PIC devices: 16F, 18F, dsPIC30.
EnerJar - DIY power draw meter
11. June 2008 - 14:19 — adminThe EnerJar is an easy-to-build device that accurately measures the power draw of electrical appliances.
PIC MIDI controller
31. May 2008 - 11:55 — adminThis MIDI Controller uses a PIC16F877A Micro and a 2 pin LCD Character Display.
