IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller

Introduction This little project will demonstrate how you can use your old NEC IR protocol based TV,DVD or VCR remote control to control you home appliances like fan bulb or virtually anything. Consumer IR protocols There are a number of consumer Infrared protocols out there and they have been used for every single purpose possible i guess, like PDA laptops and other consumer appliances. RC-5 & RC-6 by Phillips , RCA are few examples of consumer IR protocols. In this demonstration we will stick the to NEC protocol by NEC corporation, NEC Protocol Based Remote Control for this Bord Remote Control for This Board NEC Infrared Protocol

Pickit 2 clone The Universal Microchip PIC Programmer /Debugger

About The programmer The PICkit™ 2 Programmer/Debugger is a low-cost development tool with an easy to use interface for programming and debugging Microchip’s Flash families of microcontrollers. The full featured Windows programming interface supports baseline, mid-range, PIC18,8-bit, 16-bit, and 32-bit microcontrollers, and many Microchip Serial EEPROM products. With Microchip’s powerful MPLAB Integrated Development Environment (IDE) the PICkit 2 enables in circuit debugging on most PIC microcontrollers. In-Circuit-Debugging runs, halts and single steps the program while the PIC microcontroller is embedded in the application. When halted at a breakpoint, the file registers can be examined and modified. Features 1. This device will work like the normal pickit2. 2. This wll work for any pic (5 and 3.3V devices) 3. No mosfets no complex, only one voltage boost circuit. 4. you can program the target without PC. ...

USB 8051 (89 series) & AVR Microcontroller Programmer

About the programmer This simple microcontroller programmer can progam most of the 89 like Atmel's AT89S51, AT89S52, AT89S53, AT89S8252, AT89S8253 including the Atmel AVR series of microcontroller , it does not support 89C series . It simply consists of an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed. Features Works under multiple platforms. Linux, Mac OS X and Windows are tested. No special controllers or smd components are needed. Programming speed is up to 5kBytes/sec. SCK option to support targets with low clock speed (< 1,5MHz). if you have all ready have your USBasp programmer, which is previously posted on my blog as USB AVR PROGRAMMER then there is no need build new hardware you just need to change the firmware of the programmer microcontroller. Simple Steps to made This programmer Step ...

60 Mhz Frequency Meter / counter

Introduction This is 60 MHz frequency meter / counter for measuring frequency from 10 Hz to 60 MHz with 10 Hz resolution. The meter provides very stable readings and has excellent input sensitivity thanks to on board amplifier and TTL converter, so it can even measure weak signals from crystal oscillators. With the addition of prescaller it is possible to measure the frequency of 1GHz and above. The basic idea comes from the AN592 Microchip application note: "Frequency counter using PIC16C5x" where you may find a simple software wich implements a frequency counter using a PIC microcontroller.I wrote a specifically designed software to improve the counter resolution, to handle the IF mode and value by means of an operating menu, to decode and edit the read frequency on an LCD display. The result was a simple and effective device.
