Small LED dot matrix development board I was very busy for the past two months so this blog just didn’t move. As you may know, the LED dot matrix display is my favorite device. I have designed a small development board for testing my led dot matrix related programs. The PCB is single sided so […]

This PIC project uses an I2C Real Time Clock IC (DS1307) and a four digit seven segment display to create a standard desk clock. Note: If you typed DS1703 Real Time Clock to find this page you probably mis-spelled the chip type. Anyway you can find a DS1307 (RTC) Real Time Clock IC project and information

This post provides a simple digital clock implementation using PIC12F675 microcontroller and an LCD display. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom of this page. In this article, it is assumed that you know, How to interface LCD with

Remember those good old days when everyone had those giant sound systems in their living room? Besides the inconvenience of the CDs, the sound experience was extremely fun, and they’re always was a small star in the show: the small screen with the VU animations. Unfortunately, they fell into the pile of old electronics, often being

Red digits on this photo appear to float in the air in front of the clock. This illusion is based on inertia of a human eye. If LED-formed digits will periodically and frequently enough flash, they will appear solid and steady. And since the matrix of digits is formed by a mechanically scanned single line

I can’t take credit for the design of this one. I bought the gear as a clock a few years ago. It was mounted on a frame and had one of those cheap clock units running it. The gear is designed to be driven by the minute-hand shaft of the clock mechanism. The problem was

This is the first clock I ever built. I’ve built a few LED signs, but they get boring because I already know the message. How this clock works: A motor spins the “propeller”, and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7

This LED clock may not be the easiest to build but surely it is the one with fewer parts that you can find, for that reason I call it “The ANP LED Clock”. (ANP stands for Almost No Parts.) Using the micro controller PIC 16F84A or the 16F628 (same pinout), this clock have more and

LED Binary Clock This is the second revision of my PIC based LED binary clock. The original version was the first PIC project I attempted, it used a PIC16F84A to do both the timekeeping and control the display matrix, unfortunately it didn’t keep good enough time and gained about a minute every week. This second
