A 12hr/24hr LED Clock with display control using PIC16F628A microcontroller
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...

Countdown Timer using PIC16F84 microcontroller
It’s a kitchen timer. Use it to time spaghetti, or maybe an egg. It uses two PICs, one acts as a keyboard encoder, the other drives the display and supports the timer functions. You key in the desired...

Internal Oscillator Recalibration Utility for PIC12F629
Description The PIC 12F629 and 12F675 devices have an internal 4Mhz oscillator that enables the devices to be used without an external crystal or RC network. This frees up one or two pins for I/O use...

Digital alarm clock using PIC16F877 microcontroller
This is an alarm clock I built. It was very effective during the sort time I used it, because I programmed it to play a very annoying tune through a speaker. I actually started to wake up before the...

Propeller Clock Mechanically Scanned LED Clock using PIC16C84
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...

Gear Clock using PIC16F676 Microcontroller
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...

Build a digital clock with its digits levitating in the air using PIC16F84
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...
