Introduction I always thought the clapper so cool. For those who are lazy like me, turn on or off the bedroom light without getting out of bed, simple clap your hands is amazing. Thinking about it I projected one for me. Several projects of clappers can be found on the Internet, and most of them […]

Abstract: A circuit and program listing for using the MAX6955 LED display driver with a PIC microcontroller and 14-segment displays. The MAX6955 is an LED display driver with an I2C™-compatible, serial interface capable of supporting Fast Mode speeds up to 400kHz. It is capable of driving sixteen 7-segment, eight 14-segment, eight 16-segment or 128 separate LEDs.

Introduction I have been using the toner transfer method for about 9 years with great results. Occasionally I would need a board with finer traces and I would use UV method. My exposure setup allowed only a single sided board to be made and it was composed of a 30cm UV tube, some holders, a

Smart Button This is a button a little bit smarter. (Microcontrollers and coffee, who doesn’t like) I i’m using it to fill my Coffeemaker with water. This way its a little bit more fun and i always get the same amount of water. Its a simple project, and it’s a good excuse to play with a PIC10F,

The intel 8051 series 8bit microcontroller, originally introduced in 1980, remains popular and has had perhaps the longest product life of all such devices. It has become the industry standard for real-time and Boolean control applications. While some (who should know better) have said that the 8051 is dead, it continues to be a viable

Introduction When working with microcontrollers that require a factory calibrated osccal value stored in memory, its very normal that once in a while this setting could be lost during an upload of a new program or when accidentally erasing the device. Im no exception and erased many times this value by mistake in several devices.

Microcontroller was invented by Intel sometimes in the 80s ever since that invention other Electronics companies such as Atmel, Microchip and Motorola etc have manufactured different brands of Microcontroller like AT89, PIC16F and 68H All microcontrollers performs specific task based on the set of instructions giving to them through a process called Programming language. Example
A large number of embedded project require some type of user interface. This includes displaying numerical, textual and graphical data to user. For very simple numerical display we can use 7 segment displays. If the requirement is little more than that, like displaying some alphanumeric text, we can use LCD Modules. They are cheap enough

Introduction USB is very common interface today. If you look around, many of devices today comes with a USB port. Computers, printers, routers, usb keys, etc. All this devices have a USB controller inside. These devices can be divided in two groups: USB Host (like a computer, routers, modern LCD TV’s); USB Device (like flash
