A Digital Clock can be made easily by using PIC Microcontroller, DS1307 and a 16*2 LCD. I have already posted about Interfacing DS1307 RTC with PIC Microcontroller. The DS1307 RTC can work either in 24-hour mode or 12-hour mode with AM/PM indicator. It automatically adjusts for months fewer than 31 days including leap year compensation […]

I decided to build a device to permanently display accurate time received from a cheap GPS module installed in my workshop. Having obtained a PIC18F1320 microcontroller for experimentation, I wanted to learn about the new features of the PIC18F range using only minimal hardware to control the display. I am currently using it with the

This is a simple countdown-timer-on-a-chip project – you program the PIC, attach some buttons and a pair of 2-segment LEDs, and you are done. I used this timer for one of my projects, but I tried to make that timer as generic as possible, so it can have other applications. On this site I describe

Here is 0 to 99 minutes relay timer using PIC16F628 microcontroller and 16 character LCD display. The microcontroller is PIC16F628A running at 4.0 MHz clock using an external crystal. An HD44780 based 16×2 character LCD is the main display unit of the project where you can watch and set the timer duration using tact switch

You can use a PIC microcontroller and an LED matrix to create a binary clock (or if you prefer you can wire up individual LEDs). This project uses an LED matrix block as it saves lots of wiring. So what is it ? Its an led clock that displays the time information as binary numbers…

GPS satellites and GPS Ground Segment need extremely accurate timing to allow GPS users to know their own position on the Earth. Rubidium and Cesium clock generators are extensively used and maintained to synchronize and generate the signals that our inexpensive navigator gets from the GPS satellites orbiting at 20000 Km. Many commercial systems use

In this post I’m going to show you how to interface an I2C Real Time Clock – RTC with PIC microcontroller. Only a basic hardware configuration and a communication protocol are presented here. I’m planning to extend it to a more advanced design in a near future. Although PCF8573 was used a similar IC’s like

Build a timer with Motorola Nitron MCU and using ICC08 to develop c program. Loader schematic also included. New s-record for 8-pin 68HC908QT2! My son got his fan in the bedroom. The fan has mechanical timer for 0-180mins. One day it broken. So I got the idea to use Nitron chip to replace the mechanical
