Hello,
I am new to this forum and am VERY slowly refreshing my apparently very poor electronic knowledge.
Part of the circuit is to display a number, it is actually counting the number of litres of water pumped along a water line. I would like however to display it using either a dot matrix or LCD display rather than an 7-segment LED, which will make me look like the amateur I clearly am! I have rediscovered the 4510 and 4511 that take the clock circuit from the 555 timer and convert it into the signal for the 7 segment display but cannot find anywhere that enables me to use a simple circuit for the display using a LCD or dotmatrix WITHOUT using a PIC? Is it possible to use a couple of chips and a dot-matrix display or do you have to go some more complicated method using something like a PIC?
I desperately don't want to use an 7segment - I want the finished article to look professional and would love to use an dotmatrix or some-such.
Any help would be greatly received.
Paul
