What is the Analog Style LED Clock and how does it work?
The clock was originally designed as my Senior Project to complete my Electrical Engineering Degree. This project generated a lot of interest while I was developing it. As a result, I have decided to offer the project as a kit that you can build yourself. An assembly, operation, and technical manual is included, complete with theory of operation, schematics, and drawings. Get your Analog Style LED Clock Kit today!
The goal originally was to independently drive 180 LEDs, read two pushbuttons and monitor the 60Hz line, all with an 18-pin processor. But then the instructor said that I needed to add an alarm function. I decided that I would add a buzzer for the alarm, an “Alarm” LED, a “PM” LED and two more pushbuttons … and not increase the pin count of the processor!
How was this made possible? The picture above shows the completed clock. All of the components are visible. There are no hidden components, no other driver circuits. The LEDs are regular high-intensity LEDs; nothing special about them. A total of 182 LEDs, 4 pushbuttons, a buzzer and monitoring the 60Hz line … all ran by just the 18-pin controller in the center of the board! Check out the manual for a complete explanation of how it works!
