Hi everyone, its Barry here I haven't been here for a while as I have been very busy working on a tough project.
Well I'm calling out for your help again, I am trying to build a circuit that has a circular matrix of about 40 traffic light LED's (green, amber, Red) the LED's are supposed to light up in sequence (green to amber to red) in response to a signal but as a relative novice I simply cannot figure out how to make this happen, I've looked at counters, I have looked at A-stable vibrators and even the good old 555 and nothing seems to work, does anyone have a chip or a particular chip configuration (with a clear explanation) that could solve this problem ?
The second problem is I need a simple wireless switch to initiate this sequence, more specifically I need a switch that will trigger the sequence above when it detects the correct radio frequency (that is the signal). I understand that this is quite a detailed problem so I would be very grateful to anyone who has the expertise and would be good enough to take the time to share their knowledge and give a detailed answer, theoretical or practical.
Thank You all so much.
Barry
