This little project will demonstrate how you can use NEC IR protocol based TV, DVD or VCR remote control to control you home appliances like fan bulb or virtually anything. There are lots of projects out there to accomplish this task but i have to write my own code because of too many requests on […]
Description This project is a 3 button mini IR remote control which transmits 12-bit SIRC IR signals as used by Sony remote controls. It has been designed to work with both the 2-channel relay driver board and 3-channel relay driver board projects also on this website. The board uses Microchip’s low cost PIC10F200 microcontroller along […]
Description This project uses a MicrochipPIC microcontroller, a serial EEPROM and a thermistor to create a temperature recorder. Performance The temperature is measured and stored at user programmable intervals; this can be from 1 second to 256 seconds. The time interval is set by programming it and the start time into the EEPROM. Most of […]
BOOTLOAD PIC18F4550 – FIRMWARE UPDATING SETTING THE PIC18F4550 IN RD/WR ( BOOTLOAD ) MODE FOR BOOTLOADING Loading / updating new code into the USB INTERFACE BOARD can be done with a Bootloader Software. While searching for good bootloader, I found some nice tutorial on eegeek.net and piccoder.co.uk for BOOTLOADING the USB INTERFACE board. The tutorial […]
Introduction The idea of this project is to control (switch off/on) two power sockets with a computer by using its USB port. I’ve chosen USB in first place because I wanted to experiment with the PIC18F4550 microchip’s microcontroller, and secondly because the power supplied by this port (500mA) is enough to activate a relay without […]
Intro Here you can find all resources you need to build your own in-circuit serial PIC16F87X programmer. After experimenting with the PIC16F84, time had come to move on to more powerful devices, such as the PIC16F871. These devices offer a low voltage progamming (LVP) mode. This basically means that it is possible to modify the […]
PIC18F4550 USB DEMO INTERFACE BOARD PROJECT This project / USB hardware is quiet easy to make at home with few components, this piece of hardware will be detected by your computer like any other external device once it’s completed. This is a Simple USB demo interface development board project and demonstrate excellent USB interface to […]
Description Schaer is a generic programmer circuit capable of uploading and downloading firmware to/from several electronic devices like microcontrollers and eeproms. This and other programmers came to my attention when I was working in CAMBADA, the robotic soccer team from the University of Aveiro, and since all other programmers available there were too expensive for me to buy […]
Stepper Motor Tutorial In this tutorial we are going to drive a Single unipolar stepper motor using PIC18F4550 Microcontroller in various different stepping modes. The source code and Project files are free to download at the end of this page. Stepper motor due its excellent features is very famous in between hobbyist for various robotic […]
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 […]
