As a fan of taking my dihydrogen monoxide in straight, uncut, uncorrupted liquid form, I purchased a six stage reverse osmosis filter some years ago. My filter is a few years old now, and the super calcium enriched water we have in Michigan has taken its toll. The filter used to shut off when the […]

MintLite Part I

MintLite – The Luxeon Powered Mint Tin Flashlight! This idea has been rattling around in my head for more than a month now, and I finally have thought it out enough to do some doodling in Eagle. The basic idea is built around a six watt Luxeon K2. I plan to use a pair of

Interfacing of PIC16F84A with i2c based 24LC64 EEPROM

Interfacing of PIC16F84A with (i2c based) 24LC64 EEPROM (Code + Proteus simulation)

This post provides the code for interfacing 24LC64 EEPROM with PIC16F84A microcontroller. This 24LC64 EEPROM has i2c based interface and PIC16F84A doesn’t have any built in i2c modules, so software i2c module is created in the code. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section

LED Matrix Backpack schematic
