Hi,
Am sure there is a very easy answer to this! I'm getting back in to electronics and need some help with how to construct a circuit.
Essentially I am looking to build an LED clock which has an "analogue" look to it. I've done a normal clock a few years back using 4017 ics (so have a basic electronics understanding) but they're not of use this time.
If I take the seconds display which will explain this best, what I want is to, over the course of 1 minute, light 60 LEDs around a clockface. Each LED will remain lit until second "zero" is reached again when the display resets.
Thus:
time display
0 blank
1 LED 1 illuminates
2 LED 1 remains illuminated and LED 2 illuminates
.
.
.
59 LEDs 1, 2..., 58 remain illuminated and LED 59 illuminates
0 LEDs reset
With minutes and hours I will do something similar though with only one LED lit at any time.
My question is, is there an easy way to achieve the above either with transistors or basic logic gates? I'd like to build this using readily available chips without having to go down the PIC/programming route.
Any help greatly appreciated.
