This is a my second Digital Clock project.Which is having 5.5" height 6 digits seven segments.
Working with PIC16F876A microcontroller
Power : 12V DC / Ampere : 1.2A Max
Time Display : Hours / Minutes / Seconds
Length : 24 inch
Height : 7inch
I will add a fully completed clock picture with aluminium frame which I made. :-)
