How to Interface I2C External EEPROM 24LC64 to PIC Microcontroller

Leave a Comment / Using Pic Microcontroller / By Tech Master

Microcontrollers are standalone chips since they have memory and processor embedded. The integrated memory of microcontrollers store embedded code and other temporary variables for the execution of program. CircuitsGallery published many microcontroller tutorials and PIC microcontroller projects. Sometimes we may use non-volatile memories (i2c devices) with microcontrollers in case of storing permanent data. In this article I …

PIC USB HID (Human Interface Device) Interfacing

Leave a Comment / Using Pic Microcontroller / By Tech Master

For long time, UART is the only and best way to interface with PC. It is easy to adapt and handle. Though some devices (like: GSM modem etc.) have UART on themselves, but for interfacing with PC, there is only one thing now and that is USB Introduction The purpose of this article is to …

Interfacing DS1307 Real time clock with PIC16f877

Leave a Comment / Using Pic Microcontroller / By Tech Master

In any advance project we need real time clock synchronize with our work and for this purpose the best option is DS1307 (RTC Ic). Interfacing DS1307 Real time clock with PIC16f877 is done by I2C communication. To know I2C protocol you may refer my previous post “Interfacing external EEPROM with PIC Microcontroller”. To know about …

ATTiny2313 Multi-mode LED Matrix Clock

Leave a Comment / Using Atmega / By Tech Master

This is a mutli-mode clock project based on attiny2313. it employs a 8×8 led matrix as display. with the limited resolution, this 12 hour clock shows time in 6 different modes. The circuit employs row and column multiplexing to drive the leds, one row at a time, this gives a 12.5% duty cycle when “sets” of leds (8 of them …

LED Driver MAX7219 – clock Using Atmega

Leave a Comment / LED Projects / By Tech Master

Below is the schematic that shows how the IC is wired to the ATMEGA328 microcontroller and the 4 digit 7-segment display with comon cathode. Besides the MAX7219 you need only three other external components: two capacitors and one resistor. The capacitors are here to reduce noise signals and cannot be ommited. The resistor is used …

How to make an Arduino Pro Mini bare bones with Real-time Clock Using Atmega

Leave a Comment / LED Projects / By Tech Master

Recapitulation One thing I didn’t find clearly over the internet is how to make an Arduino Pro Mini bare bones, that is, from the scratch, and how to make one on the breadboard. This is really useful if you want to make a custom pcb/smd circuit, because you will be able to test your hardware …

GPS Clock Prototyping

Leave a Comment / Tech News Updates / By TechExpert

A while back I picked up a Spark Fun 128×64 LCD and an Ada fruit 66-channel GPS module to have a go at making a GPS clock. The great thing about setting the time and date via GPS is that I won’t have to put any buttons on the clock. It’ll set itself, and appear …
